Diagnostic Fault Information

Circuit/System Description

The front and rear suspension position sensors provide the headlamp control module with front and rear suspension position information. Each

sensor receives a 5 V reference, signal, and low reference circuits from the headlamp control module. The sensor are connected to the control arms

at the front and rear suspension. As the vehicle travels, the suspension compresses and rebounds moving the suspension position sensor arms. This

causes the signal output of the sensors to change. The headlamp control module compares the information from the front and rear suspension

position sensors and adjusts the headlamp leveling as needed.
