Diagnostic Fault Information

Circuit/System Description

The electronic suspension control (ESC) module supplies a 5 volt reference signal to each suspension position sensor. The suspension position

sensors supply an voltage signal of 0.35-4.75 volts to the ESC module which represents the position between the body and the wheel. The sensors

are also grounded through the ESC module.

Conditions for Running the DTC

* Battery voltage is between 9-16 volts

* Ignition is ON

Conditions for Setting the DTC

* The DTC is set when the ESC module measures a position sensor signal voltage below 0.35 volt or above 4.75 volts for more than 1 second

while the vehicle is operated under normal driving conditions.

* The fault is detected during 3 consecutive ignition cycles, or during the same ignition cycle after clearing the DTC with a scan tool.

Action Taken When the DTC Sets

* The ESC will enter the speed dependent damping mode.

* Both left and right normal force outputs will be set to the default output states.
