Accessory load sensors A load cell (or loadcell) is a transducer which converts force into measurable electrical output. Although there are many varieties of force sensors, strain gauge load cells are the most commonly used type. Knock sensors. A car knock sensor is located on the intake manifold, cylinder, or engine block. The purpose of the knock sensor is to sense unusual pulsations caused by the engine detonation. 16. Describe the key features of electronic control units (ECU’s) listed in the table below. Read only Memory (ROM) Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM is electronically modified after the manufacture of the memory device. Programmable read-only memory (PROM) A programmable read-only memory (PROM) is a form of digital memory where a fuse or anti-fuse locks the setting of each bit. (e- FUSEs are also used) It is one type of ROM (readonly memory). The data in them are permanent and cannot be changed. Electronically erasable programmable read-only memory (EEPROM) EEPROM (electrically erasable programmable read-only memory) is user-modifiable readonly memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than usual electrical voltage. Unlike EPROM chips, EEPROMs do not need to be removed from the computer to be modified Random access memory (RAM) Random-access memory is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. Multiplexing Multiplexing is a way of sending multiple signals or streams of information over a communications link at the same time in the form of a single, complex signal; the receiver recovers the separate signals, a process called demultiplexing Adaptive learning Adaptive Learning is a strategy used by O.E.M. automotive manufacturers to maintain long term tuning accuracy. This strategy allows for continuously changing climate conditions to be always compensated for by the ECU. This strategy is vastly different from closed-loop type control systems J:\VET\Automotive\AUR30620 - Cert III Light Vehicle Mech Tech\AURETR123\STUDENT ASSESSMENT GUIDE\AURETR123 Student Assessment - Theory v1.1.docx

18. Describe the purpose and operation of ignition systems and components in the listed in the table below. Spark plugs A spark plug is essentially two electrodes that are mounted such that a high-voltage spark leaps over them. Ignition leads. It transport energy from the coil to the spark plug Ignition coils, including electromagnetic induction. The coil is the focal point of the ignition system. Its sole function is to transform 9-12 volts into thousands of volts so that there is enough voltage to make the spark plug move between the electrodes. Ignition timing, including variable ignition timing according to engine load, speed and knock sensor input. Ignition timing controls when the spark plug fires during the Compression Stroke. Ignition timing is measured in degrees of crankshaft rotation before top dead centre (BTDC). Dwell period In ignition systems, Dwell refers to the period of time that the coil is turned on. That is, it is the length of time that current flows through the primary winding of the coil. In old points systems, it is time the points are closed 19. Describe the purpose and operation of ECU control of ignition coil switching and methods of generating timing signals, listed below: a) Crankshaft position sensor signals including inductive pick-up, Hall effect and light emitting diode (LED). Profile Ignition Pick-up (PIP) is a Hall Effect magnetic sensor that triggers the TFl and injectors, There is a shutter wheel alternately covers and uncovers a fixed magnet as it rotates. The change in the magnetic field activates the sensor. The purpose of a TFI module is to control the spark output of the ignition system. A signal is sent from the TFl to the ECU, where the ECU processes the received signal and correspondingly outputs the correct spark control for engine timing. b) Waste Spark Ignition Systems. The wasted spark system is an ignition system used in some four-stroke cycle internal combustion engines. In a worn spark system, the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke. c) Coil-on-plug ignition systems.

7. Describe the operating principles of the following vehicle dynamic control systems and associated components listed in the table below. Active roll over protection Active rollover protection is a system which prevents a vehicle from rolling over from excessive lateral force. There are two ways to control this: 1 Electronic stability program (ESP). Comprising traction control, anti-lock braking and yaw control. 2 Active suspension. Adjusts the suspension if the yaw sensor detects a possible rollover. Anti-lock braking ABS works by releasing and then reapplying or 'pumping' the brakes to a motorcycle wheel or car wheels in heavy braking situations. Sensors on each wheel are used to detect 'locking' or when a wheel stops moving and starts to skid. Brake assist Brake assist is a passive safety technology, meaning the driver does not actively apply it. These systems automatically kick in whenever extra brake force is deemed necessary to prevent an accident. Brake assist kicks in when a driver applies their brakes suddenly and with a great deal of force. Descent control The hill descent control (HDC) system allows a controlled hill descent in rough terrain without the driver needing to touch the brake pedal. With the system on, the vehicle will descend using the ABS braking system to control each wheel speed through sensor input. If the vehicle accelerates without driver input, the system will automatically apply the brakes to slow down to the desired vehicle speed. Control buttons can adjust the speed to a comfortable level. Applying pressure to the accelerator or brake pedal will override the HDC system. Electronic brake force distribution Electronic brake-force distribution occurs ahead of anti-lock braking. Its electronic program operates the inlet valves to the rear brakes. The valves will be opened and closed, as required, to control the fluid pressure applied to the rear wheels. EBD uses its computer program to operate the ABS components. The anti-lock braking function of the ABS will not be in operation (it will only come into operation if required for the particular driving or braking conditions). Electronic park brake On vehicles with an electronic parking brake (EPB), the electronic control unit operates the parking brake. Some systems apply and release with a driver-applied button. Others utilise sensors which have the ability to apply automatically /var/filecabinet/temp/converter_assets/32/3c/323c2e08502a15722d53e6ada32e00ee471661d2.docx

when the vehicle comes to a full stop. Sensors can also provide incline detection, backward motion detection, boot, bonnet or doors being opened and the driver's seatbelt not being latched. From the driver's seat, the EPB can only be released when the brake pedal is being pressed. It also can be used as an emergency brake and as a hill start assist. With the vehicle stopped and the brake pedal pressed, pulling the EPB switch applies the parking brake. The driver can release the switch and brake pedal, and the EPB will release automatically when the accelerator is pressed. Hill-start assist Hill-start assist prevents the vehicle from rolling backwards when starting on an uphill slope by maintaining the brake pressure while the driver shifts from the brake to the accelerator pedal. This can be performed by either the ESP or EPB. Stability control The electronic stability program (ESP) is an active safety system. It uses additional electronic controls to operate the brakes, in conjunction with ABS, to provide vehicle stability. This is applied particularly during cornering. ABS senses the need to apply or release the brakes on each wheel independently and ESP makes use of this facility. A brief comparison of an electronic stability program (ESP) with the other systems is: the anti-lock braking system (ABS) prevents the wheels from locking and skidding; the traction control system (TCS) prevents the wheels from spinning and the electronic stability program (ESP) provides steering stability. ESP can stabilise steering by intervention in two different ways: by braking selected wheels, or by accelerating the driving wheels. This helps to keep the vehicle stable on the road. Traction control Traction control operates by reducing engine torque, and this reduces traction between the tyres and the road. It can also use ABS to apply the brakes to reduce wheel spin. Engine torque can be decreased in three ways: 1 By reducing or cutting off fuel from the injectors. 2 By retarding the ignition. 3 By closing the throttle valve. Where traction control is fitted, the ABS electronic control unit has extra programming for traction control and often extra valves in /var/filecabinet/temp/converter_assets/32/3c/323c2e08502a15722d53e6ada32e00ee471661d2.docx

the modulator. When driving conditions are such that traction control is needed, the ABS/TC electronic control unit sends a signal to the engine PCM, telling it to reduce engine torque. The engine ECU then reduces the fuel from the injectors, retards the ignition or, in some systems, closes the throttle valve. Active and passive collision avoidance Active safety features prevent accidents from happening. Passive safety features lessen the chance of death and serious injury in instances where an accident is unavoidable. Active: Adaptive Cruise Control: More preventative than reactive, these systems use radar or lasers to adjust your cruise control speed via throttle to maintain an appropriate distance from the vehicle in front of you. Automatic Emergency Braking (AEB): Brakes are automatically applied based on feedback from sensors in order to prevent a collision or minimize collision speed Rear Automatic Emergency Braking: Brakes are automatically applied to prevent the vehicle from backing into an object using a cross-traffic monitoring system or sensors like radar or lasers. Passive: Electronic Stability Control (ESC): An extension of antilock brake technology, ESC automatically applies your brakes to help steer the car appropriately during a loss of traction. An onboard computer monitors various sensors to determine which wheels to brake and which to accelerate. Parking Assist: Feedback from ca Lane keeping assist Lane keeping assist uses a video camera to detect the lane markings ahead of the vehicle and to monitor the vehicle's position in its lane. If the vehicle's distance to the lane markings falls below a defined minimum, the system steps in. Occupant detection systems The Occupant Detection System, or ODS, is an important safety system that detects the presence of a child, infant or small adult in the front passenger seat, and for their safety suppresses airbag deployment. /var/filecabinet/temp/converter_assets/32/3c/323c2e08502a15722d53e6ada32e00ee471661d2.docx

Adaptive cruise control Adaptive Cruise Control: More preventative than reactive, these systems use radar or lasers to adjust your cruise control speed via throttle to maintain an appropriate distance from the vehicle in front of you. Roll-over protection. Rollover protection system is a system or structure mean to protect equipment operators and motorists from injuries caused by vehicle overturns or rollovers. Like roll cages and roll bars in cars and trucks, a ROPS involves bars attached to the frame that maintain a space for the operator's body in the event of rollover. 8. Describe the purpose and operation of vehicle dynamic control systems and components listed in the table below. ABS, including system inputs, electronic control unit (ECU), ABS modulator and system outputs. ABS is a system that modulates brake pressure in an emergency stop to keep the wheels from locking up. This allows the driver to maintain control of the steering wheel and stop the car as quickly as possible. How it works: 1. Brake pedal is pushed 2. Wheel sensors detect skidding or 'locking' 3. ABS pumps the brakes TCS, including system inputs, electronic control unit (ECI), ABS modulator and system outputs including associated throttle and braking system controls. The anti-lock braking system can operate in conjunction with traction control. With ABS, the hydraulic modulator uses its internal hydraulic pump to boost or reduce the master cylinder pressure. For traction control at lower speeds, hydraulic pressure from the pump is used without the driver applying the brakes. The ABS/TCS electronic control unit processes inputs from the wheel sensors and applies a brake when needed. The ABS/TCS hydraulic modulator has extra valves for traction control. These are the priming and switching valves. They are opened and closed by the ECU to control the brake fluid flowing to and from the master cylinder. Electronic throttle control, or drive by wire, is a device that can be used with traction control. This does away with the conventional throttle linkage or cable. The accelerator pedal is connected to an electronic sensor which signals the throttle position to the engine ECU (or PCM). The engine ECU then operates a servo motor connected to the throttle valve. For normal operation, when traction control is not working, /var/filecabinet/temp/converter_assets/32/3c/323c2e08502a15722d53e6ada32e00ee471661d2.docx

signals pass through the engine ECU and the servo motor opens the throttle valve in proportion to accelerator pedal movement. With the traction control in operation, the engine ECU takes into account signals from the anti-lock braking system/traction control ECU and adjusts the throttle valve opening accordingly. Electronic stability control (ESC). Including system inputs, including yaw and steering angle sensors, and ECU and system outputs, including associated throttle and braking system controls. Electronic stability control works by manipulating both the engine throttle and each wheel's brake. Similar to other driver aids, ESC turns on when you start your car. It operates in the background as it monitors steering wheel activity along with speed sensors on each wheel. 9. Describe the testing procedures for vehicle dynamic control systems including accessing and interpreting scan tool system data as listed in the table below. Diagnostic trouble codes (DTC) DTC is a code used to diagnose malfunctions in a vehicle or heavy equipment. DTC identifies what and where the issue is. Waveforms Determine any issues according to waveforms. Unstable waveform means abnormal and vice versa. Live Data Live data refers to reading information as it is being produced. This can be given in a numeric value or as a graph on a screen. 10. Describe the testing procedure for vehicle dynamic control system including using flow charts. Test vehicle dynamic system by OBD II scan tools. 1. Plug in vehicle. 2. Select vehicle information. 3. Select option which you want to check. 4. Follow scan tool’s actions to diagnose. 5. Find DTCs and clear. 6. Retest again. 7. Replace or repair if DTC not could be clear. 8. Recheck again. /var/filecabinet/temp/converter_assets/32/3c/323c2e08502a15722d53e6ada32e00ee471661d2.docx

11. Describe the testing procedures for vehicle dynamic control systems listed in the table below. Accessing electrical terminals and using probes without damaging connectors, fuse holders or wiring Although many low-cost test lights come with pointed probes, never use them to pierce the insulation of wiring systems as this can cause wiring to corrode. The probe is there to allow you to 'back probe' connecting plugs. There may be more than 50 different types of connecting plugs used on one vehicle. They will vary in terms of the number of wires they can accommodate, be of different colours to assist in identification and be waterproof or not waterproof. For this reason, consulting manufacturers' wiring information is vital when diagnosing system problems. Each manufacturer will provide details on how to remove the connecting pins from the plugs and how to disconnect the male from the female connecting plug. Many of the modern connecting plugs used in automotive applications will require special tools to remove the male and female pins. Each connecting pin has a locking mechanism to hold it in the plug body and a special tool is required to release the locking pins. Determining damage to system wiring and connectors The correct way to test circuits with a multimeter when tracing a wiring system is to "back probe' at the plugs. This can be very difficult with waterproof plugs. To back probe a plug, it is best to use a fine metal probe. If such a probe is not available, use a large straightened paper clip to probe from the back of the connector past the rubber seal. Care must be taken to not damage any seals. 12. Describe the repair procedures for vehicle dynamic control systems, including those in the table below. Connector removal and replacement procedure Power off first. Each connecting pin has a locking mechanism to hold it in the plug body and a special tool is required to release the locking pins. Ensure pin in correct plug without damage. Ensure connect properly not loosen. Removal and replacement procedures for vehicle dynamic control system components Removal 1. Turn the ignition switch to the OFF position. Apply the parking brake. 2. Place blocks under the front and rear tires to prevent the vehicle from moving. 3. If necessary, raise the vehicle off the ground and place safety stands under the vehicle. /var/filecabinet/temp/converter_assets/32/3c/323c2e08502a15722d53e6ada32e00ee471661d2.docx

4. Disconnect the wiring harness connector from the ESC module. 5. Remove the two mounting cap screws and nuts. Remove the ESC module Replacement 1. Install the ESC module with the two cap screws and nuts. Tighten the cap screws per the manufacturer's recommendation. 2. Connect the wiring harness connector to the ESC module. Hand tighten only. 3. Remove the stands and blocks. 4. Test the installation. Calibration and resetting procedures - After replacing parts, check all of the mounting nuts and bolts to ensure that they are all correctly tightened. It could save you and your customer a lot of time and money. - Inspect the vehicle for any clues. If you see any damage, cracks, and broken boots or if something just does not look right, it may need to be serviced and replaced. - Torque: The replacement of engine parts should be torqued according to the manufacturers’ specifications. If these are not adhered to, the loose assembly may result in poor handling and performance. You can compare the procedure used to the torque specifications they provide for your car. Checking the ABV Installation Checking the ABS Valve Installation Testing the ECU, SAS Installation Testing the ESC module Installation To test the brake pressure sensor Before road test: Wheel Speed Sensors ABS Power & Ground Connections Steering Wheel Angle Neutral Position setting (VDC / ESP only) Calibration of Decel G Sensor Correct Adjustment / Setting of Brake Pedal & Brake Pedal Switches Gear Position Inputs Road test 13. Describe the post repair procedures for vehicle dynamic control systems including those listed in the table below DTC Clearance procedures The only way to clear a PDTC is to fix the underlying problem with the vehicle that originally caused the PDTC and its corresponding DTC to set, and then allow the vehicle sufficient drive time to re- run the monitor that identified the problem in the first place. Check, record and clear DTCs Check systems and confirm they are functioning correctly Check that the key is initialised to the systems if required /var/filecabinet/temp/converter_assets/32/3c/323c2e08502a15722d53e6ada32e00ee471661d2.docx

Check for any DTCs after testing all functions Check the vehicle for cleanliness Checking for electrical connector mating When checking electrical connectors for mating, make sure that the retaining device has latched properly so that the connector cannot come apart. If there is any doubt that the connecting pins are making proper connection, carry out a resistance test by back- probing the plug from each side while wriggling the connector plug to check for poor fitting pins. Many electrical faults are caused by bad earth connections. Technical manuals will show the location of earth connections on a particular vehicle. Earth connections to the body are not generally waterproof and thus can cause a fault through rust or corrosion.

Airflow meters Monitors the flow of air entering in the engine Intake air temperature sensors It monitors the temperature of the air entering the engine. The engine computer (PCM) needs this information to estimate air density so it can balance air/fuel mixture. Crankshaft position sensors A crank sensor is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters. Camshaft position sensors The Camshaft Position Sensor detects camshaft rotation and is mounted near the cylinder head so that the sensor is opposite to the timing rotor attached to the engine camshaft. The engine ECU detects the camshaft angle and performs cylinder recognition based on the signals detected by the camshaft position sensor Battery voltage Give the appropriate supply in voltage to the ignition coils or distributor J:\VET\Automotive\AUR30620 - Cert III Light Vehicle Mech Tech\AURETR123\STUDENT ASSESSMENT GUIDE\AURETR123 Student Assessment - Theory v1.1.docx

Accessory load sensors A load cell (or loadcell) is a transducer which converts force into measurable electrical output. Although there are many varieties of force sensors, strain gauge load cells are the most commonly used type. Knock sensors. A car knock sensor is located on the intake manifold, cylinder, or engine block. The purpose of the knock sensor is to sense unusual pulsations caused by the engine detonation. 16. Describe the key features of electronic control units (ECU’s) listed in the table below. Read only Memory (ROM) Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM is electronically modified after the manufacture of the memory device. Programmable read-only memory (PROM) A programmable read-only memory (PROM) is a form of digital memory where a fuse or anti-fuse locks the setting of each bit. (e- FUSEs are also used) It is one type of ROM (readonly memory). The data in them are permanent and cannot be changed. Electronically erasable programmable read-only memory (EEPROM) EEPROM (electrically erasable programmable read-only memory) is user-modifiable readonly memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than usual electrical voltage. Unlike EPROM chips, EEPROMs do not need to be removed from the computer to be modified Random access memory (RAM) Random-access memory is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. Multiplexing Multiplexing is a way of sending multiple signals or streams of information over a communications link at the same time in the form of a single, complex signal; the receiver recovers the separate signals, a process called demultiplexing Adaptive learning Adaptive Learning is a strategy used by O.E.M. automotive manufacturers to maintain long term tuning accuracy. This strategy allows for continuously changing climate conditions to be always compensated for by the ECU. This strategy is vastly different from closed-loop type control systems J:\VET\Automotive\AUR30620 - Cert III Light Vehicle Mech Tech\AURETR123\STUDENT ASSESSMENT GUIDE\AURETR123 Student Assessment - Theory v1.1.docx

Short-term fuel trim (STFT) Short Term Fuel Trim. Short Term Fuel Trim (STFT1 and STFT2) is the computer's immediate response to adjust the air/fuel ratio. In positive corrections, fuel is added to adjust Long-term fuel trim (LTFT) Long-term fuel trims are measured over longer time intervals by oxygen, or air-fuel ratio sensors downstream of the catalytic converter. In practice, the signal voltages these sensors generate are not directly implicated in fuel delivery strategies, although there are some exceptions to this rule Sensor reference voltage and sensor grounds The vehicles computer supplies a reference voltage to many of the onboard semen, Typically, this reference signal is 5-Vo is, On another vehicle, a may refer to the fuel pressure sensor. 17. Describe the purpose and operation of spark ignition engine management systems including systems outputs listed in the table below. Injectors Fuel injectors are parts of modern car engines that deliver fuel to the engine's combustion chamber, directly or indirectly. These small electromechanical devices are typically positioned at a certain angle to make sure the fuel is sprayed towards the engine's inlet valve or directly into the cylinder. Idle speed control devices An idle air control actuator or idle air control valve (IAC actuator/ valve) is a device commonly used in fuel-injected vehicles to control the engine idling rotational speed (RPM). In carbureted vehicles, a similar a device known as an idle speed control actuator is used. Fuel pump relays The fuel pump relay is an electronic component found on virtually all vehicles equipped with an internal combustion engine. The ignition or powertrain control module controls the fuel pump relay and when switched on, will provide current to the fuel pump so that it may J:\VET\Automotive\AUR30620 - Cert III Light Vehicle Mech Tech\AURETR123\STUDENT ASSESSMENT GUIDE\AURETR123 Student Assessment - Theory v1.1.docx

function. Engine cooling fans The cooling fan system works by forcing airflow through the radiator. Its function is to facilitate and support the engine's temperature management. It is located at the front of the vehicle, either in front or behind the radiator. Air conditioning compressor controls It refers to an air conditioning system wherein an engine-driven refrigerant compressor is cycled on and off to control the compressor capacity. When the clutch is engaged, the engine drives the compressor; when the clutch is disengaged, the engine is effectively disconnected from the compressor. Broadband intake manifolds The primary function of the intake manifold is to evenly distribute the combustion mixture (or just air in a direct injection engine) to each intake port in the cylinder head(s). Even distribution is vital to optimising the efficiency and performance of the engine. Exhaust gas recirculation solenoid controls The purpose of the exhaust gas recirculation solenoid is to control recirculate exhaust gases that have exited the engine, back into the intake manifold so that they can be re-burned. The EGR solenoid is controlled by the engine computer and activated at precise times to achieve the best performance, efficiency, and emissions from the engine Carbon cannister purge controls The original application for the purge is to avoid the emission of gasoline vapour out of the gasoline tank. Nowadays this vapour is captured by a carbon canister. The function of the valve is to control the purge flow which discharges the carbon canister content. The valve gets installed in the engine compartment. Throttle motor (drive by wire) controls In an internal combustion engine, the throttle is a means of controlling an engine's power by regulating the amount of fuel or air entering the engine. In a motor vehicle, the control used by the driver to regulate power is sometimes called the throttle, accelerator, or gas pedal. Variable valve timing controls In internal combustion engines, variable valve timing (VT) is the process of altering the timing of a valve lift event and is often used to improve performance, fuel economy or emissions. Two-stroke engines use a power valve system to get similar results to WVT. Assembly line diagnostic link (ALDL) Assembly Line Diagnostic Link or ALL is a proprietary on-board diagnostics system developed by General Motors betore the standardisation of OBD-2. Manufacturers primarily used ALL for diagnostics at their dealerships and official maintenance facilities.
