Exam 108: Electronic Stability Control Systems

What is the name of the standard test that is performed to verify ESC operation?

A diagnostic trouble code (DTC) has been set for a fault with the lateral acceleration sensor or circuit. What test could be performed to check if the sensor is working?

Traction control is being discussed. Technician A says that the computer locks both drive wheels together when one drive wheel starts to slip. Technician B says that first the brakes are applied then the engine power is reduced. Which technician is correct?

What other name is used to describe an electronic stability control (ESC) system?

Technician A says that some vehicles with the Stabilitrak system continuously monitor wheel speed conditions and modulate hydraulic force to individual wheels to maintain stability. Technician B says that vehicles using traction control systems can reduce engine torque in slippery driving conditions. Which technician is correct?

The electronic stability control (ESC) system requires that the vehicle be equipped with what type of brake system?

A flashing ESC lamp indicates a problem with the ESC system.

A lateral acceleration sensor is usually located where in the vehicle?

A traction control system can often control all of these EXCEPT ________.

Traction control uses the antilock braking system and other devices to limit ________ of the drive wheel during acceleration.

The steering wheel position sensor provides signals related to steering wheel position and size.

Which sensor is used by the ESC controller to determine the driver's intended direction?

Technician A says that many traction control systems reduce engine torque to help the drive wheels achieve traction. Technician B says that hydraulic pressure from the electrohydraulic unit supplies brake fluid pressure to the wheel brake that is spinning during a traction control event. Which technician is correct?

The driver of a vehicle with ESC has turned OFF the stability control system. What will happen the next time the vehicle is driven?

During a traction control event, which of the following strategies is usually applied first?

Some antilock braking systems use a yaw sensor. Where is this sensor usually mounted?

The hand wheel position sensor is located ________.

Which Federal Motor Vehicle Safety Standard requires electronic stability control to be on all vehicles by 2011?

In this drawing, the vehicle's intended track is "A." If driven a little too fast, the actual track is "B." This condition is known as ________.

If a vehicle tends to continue straight ahead while cornering, the condition is called ________.
