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.

Waveforms A waveform is a representation of how alternating current (AC) varies with time. The most familiar AC waveform is the sine wave, Live Data By using live data you can determine the possible causes to the problem using real time information 11. Describe the testing procedure for vehicle electronic body management systems using flow charts in five (5) steps. 1. `Find the information needed about the problem 2. Test drive 3. Gather more information on the problem to highlight the possible problems 4. Find the actual problem by testing all possibilities 5. Begin to repair the problem, then test it again to evaluate the job done 12. Describe the testing procedures listed in the table below. Accessing electrical terminals and using probes without damaging connectors, fuse holders or wiring. Using the probes of the multimeter connect the tester clip to the negative terminal of the battery. Use then probe to check for continuity Resistance and voltage drop tests. Voltage drop tests are used to find components or circuits which have excessive resistance. The VOM's positive lead should be connected to the circuit in the direction of the power source and negative lead toward the ground. Open and short circuits tests The open circuit and short circuit test are performed for determining the parameter of the transformer like their efficiency, voltage regulation, circuit constant etc. These tests are performed without the actual loading and because of this reason the very less power is required for the test. Shorts to signal, power circuits and grounds checks Remove the power feed from the circuit. Disconnect the load. Connect one lead of the metre to one end of the circuit to be tested. Connect the other lead of the metre to a good ground.If it does not display infinite resistance, there is a short to ground in the circuit. Any relatively low resistance reading on the metre is a sign of continuity to ground and a short circuit.

13. Describe the repair procedures for electronic body management systems, including procedures for removing and replacing components listed in the table below Repair procedure for electronic management systems List six (6) steps. 1 Search for one of the most common troubles in power seats: inspect the seat rails and the area under the seat with a flashlight and make sure there are no objects obstructing or preventing seat movement. 2 Inspect the fuse or circuit breaker if both front power seats fail to operate. 3 Turn on the ignition switch, but do not start the engine. Operate the power seat switch and listen for the motor running under the failed seat. If you do not hear any sound coming from the motor, lift the switch from the door panel or the side of the seat. 4 Check for incoming voltage at the switch using a test light. If there is no voltage, check the wiring between the switch and the fuse panel for an open or short. Unplug the switch and test it for continuity using a multimeter. If there is no continuity, replace the switch. 5 Test the relay if your circuit has one between the switch and the failed motor. Operate the switch and make sure the relay is receiving voltage from the switch; also, test for outgoing voltage from the relay to the motor using a test light. Make sure the relay is properly grounded. Remove or move the seat to the side if possible, for this test. If one of the voltages is not present, check that part of the wire for an open or short. If there is no outgoing voltage, test the relay for proper operation and replace it if necessary. 6 Check for incoming voltage at the failed motor or motors using a test light. If there is no incoming voltage, test the wire or wires for continuity between the motor and switch or relay, looking for an open or a short. Unplug the failed motor and test it outside, connecting the motor to the car battery using two jumper wires. If the motor still does not operate, replace it. J:\VET\Automotive\AUR30620 - Cert III Light Vehicle Mech Tech\AURETR143 \STUDENT ASSESSMENT GUIDE\AURETR143 Student Assessment - Theory v1.1.docx

Procedure for removing and replacing faulty or damaged components List five (5) steps. 1 Locate the window switch panel. This is the button used to operate your window. It is almost always on the door. However, they are rarely found on the centre console. 2. Remove the window switch panel. Be careful not to scratch up the door panel while removing the window switch, as it often requires prying. Using a shop rag or piece of cardboard under your prying tool can help. 3. Unplug the wiring connectors from the switch. You will need to test these connectors to make sure that they are providing the appropriate 12 volts to your switch. 4. Use your multi-meter to probe each connector. Set the multi-meter for D/C volts and put the prongs of your multi-meter into the connector. It should read 12 volts. 5. Test another switch. Take a switch from another door and plug it into the connectors on the malfunctioning door. If you are able to operate your window using this switch, then the original is bad and will need to be replaced. . 14. Describe the post repair procedures for electronic body management systems listed below. DTC clearing procedure A DTC code is a series of diagnostic trouble codes used by a vehicle's onboard diagnostics or OBD system to alert you when a vehicle experiences a malfunction. There are a couple of ways to eraso codes, the first one is through. Static and dynamic performance tests of electronic body management systems Test all operations that come from the module while the car is not moving (static). Then proceed to re-test all operations again while driving the vehicle, then finally check for any DTC codes.
