Exam 11: Computer Controlled Suspension Systems

When a four-wheel-drive vehicle with an automatic ride control (ARC) system is operating in four-wheel drive at 15 mph, the suspension module:

Describe two other electronic systems that are operated by the same module on a Stabilitrak® system.

Technician A says the suspension control switch must be turned on when servicing electronic air suspension components. Technician B says the suspension control switch must be turned on when lifting the front of the car with a floor jack. Who is correct?

When servicing a vehicle with an air suspension system, the air suspension switch must be turned OFF:

With regard to an engine running in an electronic air suspension system, describe the conditions required for the control module to turn on continually the air suspension warning lamp.

If an electrical fault occurs in the Stabilitrak® system, STABILITY REDUCED is displayed in the driver information center (DIC) .

On a vehicle with a stability control system, if icy road  conditions cause the vehicle to begin swerving sideways,  the stability control module:

Explain how air is forced into an air spring to raise the suspension trim height on an electronic air suspension system.

While discussing a programmed ride control (PRC)   system:

When the brakes are applied with the doors closed on a vehicle with an electronic air suspension system, the air suspension module ignores all requests from the height sensors.

In an electronic air suspension system, if the doors are closed, the brake pedal is released, and the vehicle is travelling at 65 mph, what action is taken by the chassis control module when a command is received from the rear suspension sensor to lower the vehicle?

The magneto-rheological fluid in shock absorbers or struts in an electronic suspension control system contains:

When removing an air spring valve with air pressure in the spring, rotate this valve to the fully released position.

Technician A says some rear load-leveling suspension systems have the capability to maintain the proper rear suspension height individually on each side of the vehicle. Technician B says this type of system has one rear suspension height sensor. Who is correct?

A hard fault code indicates a fault that occurs and then disappears.

Technician A says that in an electronic air suspension system with the ignition switch turned off for over 1 hour, the compressor run time is limited to 5 minutes for raise vehicle commands on the front springs. Technician B says if the brake pedal is applied when driving the car, raise vehicle commands are completed immediately. Who is correct?

An electronic rotary height sensor contains what type of switch?

If a vehicle equipped with an electronic suspension control system is accelerating rapidly at wide open throttle, what mode does the system enter?

When the input sensor signals indicate the vehicle is beginning to swerve sideways on a vehicle with a Stabilitrak® system, the EBTCM prevents the swerving action by:

Technician A says adaptive cruise control system uses a long-range radar sensor. Technician B says the lane departure warning system uses a video camera to measure lane markings. Who is correct?
