- While 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_forwardName the three main driveline components that are added to a RWD vehicle to make it a 4WD vehicle.arrow_forwardTechnician A says that limited- slip differential clutch packs are designed to slip when the vehicle turns a corner. Technician B says that a special additive is placed in the hypoid gear lubricant to promote clutch pack slippage on corners. Who is correct?arrow_forward
- A 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_forwardTechnician A says that the suspension switch must be turned off before raising any corner of a car with an electronic air suspension. Technician B says that the ignition switch must not be turned on while any corner of a car with electronic air suspension is raised. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardA technician is working on a 2005 BMW 7 series.. The compressor is running all the time and the air is cold. The tech unplugs the wiring harness leading to the compressor, but it stays running. The technician recommends a new compressor as he suspects the clutch has melted. What is likely happening here? nothing. This compressor doesn’t have a clutch, only a pulley the clutch has melted due to a slipping belt only the hub needs replacement, the pulley is fine the compressor must be seized internally for this to happenarrow_forward
- While discussing HEVs: Technician A says that in a series hybrid, the engine is only used to power a generator to recharge the batteries. Technician B says that in a parallel hybrid, the engine and/or the battery can supply the power to move the vehicle. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardWhile discussing valve body assemblies in late-model transmissions: Technician A says that the valve body is no longer needed in some electronically controlled transmissions. Technician B says that an EPC solenoid maintains constant fluid pressure through the valve body regardless of the vehicle’s operating condition. Who is correct?arrow_forwardTechnician A says if the amber ABS warning light is on continuously, the ABS system is still operational but may not be operating at 100 percent efficiency. Technician B says ABS operation might be affected by improperly turning the drums and rotors. Who is correct? a. A only b. B only c. both A and B d. neither A nor Barrow_forward
- Technician A says that if a drive belt does not have the proper tension, it may produce squealing and chirping noises. Technician B says belt tension should be checked even if the engine has an automatic belt tensioner. Who is correct?

The statement of the problem briefly addresses the question: What is the problem that the research will address?) "Comparing ABS system to hydraulic break of a vehicle"arrow_forwardWhile diagnosing the cause of TCC shudder: Technician A checks the fluid pressure sent to the clutch. Technician B says that because the shudder occurs only after the clutch is engaged, the problem is the engine, transmission, or another component of the driveline. Who is correct?arrow_forward
