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.
