A yaw sensor is used to measure forward acceleration.

Technician A says The idea behind regenerative braking is to recover some of the energy that is lost as heat when the brakes are applied and the vehicle is stopped . Technician B says Most hybrid and electric vehicles have a way to recover this lost energy as electrical power stored in the battery . Who is correct?

Technician A says s tability control is the controlled application and release of brakes at the correct time, independently of each other, to prevent an out of control vehicle during hard maneuvering . Technician B says there are two common terms for loss of steering control through a corner: understeer and oversteer . Who is correct?

Explain the difference between a yaw sensor and a G sensor.

The KIA Optima Hybrid uses a ____________driven starter-generator to help slow the vehicle during deceleration.

On some vehicles the hydraulic modulator and the EBCM are mounted together but can be serviced separately.

Technician A says that on some Chrysler tire pressure monitors send a signal to the remote control door lock receiver (RCDLR) regarding tire pressure.  Technician B says that some GM tire sensors can learn their own positions with a transponder built into the wheel well near the tire. Who is correct?

Describe the operation of a yaw sensor.

ARC is an electronically controlled traction control system.

____________ cruise control systems have the ability to maintain distance behind the vehicle in front of them by applying the brakes as necessary to slow the vehicle .

The ____________________, also called a brake pressure modulator valve , is generally composed of a valve body that contains the control valves used to is olate, decrease, and increase pressure at the individual wheels that can control the application of brake pressure according to the demands placed on the vehicle by the driver, and the optimum corrections as calculated by the VSC computer .

Technician A says on the Chevrolet Volt, the EBCM, and the brake pressure modulator are connected together, so there are no external connections to check when a code for the regeneration pressure sensor is being checked out. Technician B says the scan tool communicates with the EBCM over the vehicle network. Who is correct?

Technician A says a problem with the vehicle network can cause a problem with the electronic power steering system. Technician B says always check for any "S" codes. Who is correct?

Active cruise control is being discussed. Technician A says a ctive cruise control systems allow the driver to set the following distance of the vehicle ahead.   Technician B says brakes can be applied and the throttle reduced anytime a slower vehicle is detected ahead by the system's radar. Who is correct?

The _____________- is a cruise control system that can see drivers approximately 600 feet in front of the vehicle and apply the brakes if necessary to maintain a safe distance.
