Exam 115: Electronic Suspension Systems

What type of actuator is used on electronically controlled suspensions?

What term describes an electrical device controlled by an electronic module that performs some kind of mechanical action?

Typically, a vehicle height sensor mounts to the body of the vehicle and is connected to the ________ by a lever.

Technician A says that comparing the front vehicle height sensors to the rear sensors allows the ECM to determine body roll created by cornering force. Technician B says that vehicle height sensors are only located on the rear. Which technician is correct?

Which of the following is NOT considered an input for the suspension ECM?

Technician A says that comparing height sensors from side to side allows the ECM to calculate acceleration force. Technician B says that only Hall-effect sensors are used as height sensors. Which technician is correct?

Refer to the diagram. Technician A says that the ELC fuse supplies power to the RIM. Technician B says that an open circuit at the splice pack will prevent the relay from working. Which technician is correct?

Which sensor can be tested by unbolting the sensor and, with the ignition on, engine off (KOEO), looking at the scan tool data?

A lateral acceleration sensor is used to provide the suspension control module with feedback regarding ________ force.

Two technicians are discussing the length of an actuators' duty cycle. What type signal are they most likely discussing?

Technician A says that some GM vehicles have only one height sensor. Technician B says that GM vehicles may have up to four height sensors. Which technician is correct?

Why is the typical rear load-leveling system connected to the ignition circuit?

Which of the following is the LEAST likely sensor to cause an electronic suspension fault?

Two technicians are discussing electronic leveling systems. Technician A says battery power may be applied directly to the compressor. Technician B says most leveling systems use adjustable sensors. Which technician is correct?

Technician A says that an electronic control module used in the suspension system is the same as that used for engine control. Technician B says that most electronically controlled suspension systems use a separate electronic control module. Which technician is correct?

Where is the steering wheel sensor typically located?

Which sensor provides input regarding cornering forces?

How many wires are used with a potentiometer-type sensor?

Technician A says that a potentiometer returns a digital signal to the ECM. Technician B says that a potentiometer generally has a two terminal harness connected to it. Which technician is correct?

A steering wheel position sensor is being discussed. Technician A says that the sensor is used to determine the direction of the steering wheel. Technician B says that the sensor detects how fast the steering wheel is turned. Which technician is correct?
