- Name the three main driveline components that are added to a RWD vehicle to make it a 4WD vehicle.arrow_forwardMost late-model transmission control systems have adaptive learning. What does this mean?arrow_forwardWhile discussing the CVT transaxie used in Toyota hybrid vehicles: Technician A says that the transaxie contains two electric motor/generators, a differential, and a simple planetary gearset. Technician B says that the planetary gearset adjusts the diameter of the pulleys to provide the various speed ratios. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forward
- Technician A says that a seized shift linkage may cause the transfer case to operate only in 4WD. Technician B says that a worn and loose linkage may cause a transfer case to operate only in 2WD. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardA 3-degree difference in the SAI angle on each side of the front suspension may cause a FWD vehicle to have increased during hard acceleration.arrow_forwardWhile discussing automatic AWD systems: Technician A says that the systems operate in 2WD nearly all of the time. Technician B says that on many systems, when the PCM receives inputs from the CAN bus, it indicates that wheel slippage power is sent to the other drive axle. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forward
- While discussing AWD systems: Technician A says that some systems are electronically controlled and use an electromagnetic clutch to engage and disengage the drive axles. Technician B says that some cars do not use a transfer case, but they are equipped with a third differential unit. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardAn electronically controlled transmission has erratic shifting: Technician A says that a poor PCM ground will cause this problem. Technician B says that a bad AC generator-to-battery circuit will cause erratic performance of a transmission or transaxle. Who is correct?arrow_forwardDescribe the current technology on Electronic Power steering system on certain vehicle model. The explanation must include the picture of the component together with its function.arrow_forward
- What is a suspension system.arrow_forwardTechnician A says that some systems use a special modulated shift control solenoid. Technician B says that some systems use a special modulated converter clutch control solenoid. Who is correct? Technician A says that shift solenoids direct fluid flow to and away from the apply devices in the transmission. Technician B says that shift solenoids are used to mechanically apply a friction brake or multiple-disc clutch assembly. Who is correct? Technician A says that throttle position is an important input in most electronic shift control systems. Technician B says that vehicle speed is an important input for most electronic shift control systems. Who is correct? Technician A says that a faulty TP sensor can cause delayed shifts. Technician B says that delayed shifts can be caused by an open shift solenoid. Who is correct? Technician A says that some shift solenoids can be activated by providing a ground for the solenoid. Technician B says that some shift solenoids can be activated by…arrow_forwardMaster cylinder Check valve HPACHigh Pressure Accumulator) Plunger pump Solenoid valve LPA (Low Pressure Accumulator) RL Wheel Cylinder FR Wheel Cylinder FL Wheel Cylinder RR Wheel Cylinder Figure 2: Hydraulic Control Unit (ABS) Figure 2 above shows the layout of the Antilock Braking System (ABS) Hydraulic Unit during the system is in Normal position. b) What would happen if the ABS system having a fault?
