Diagnostic Fault Information
Circuit/System Description
The electronic suspension control module (ESCM) commands variable levels of pulse width modulated current to each damper in response to rough
road, or abrupt steering maneuver driving conditions. The ESC module continuously compares each dampers command state with the state of their
feedback circuits to ensure they agree.
Conditions for Running the DTC
* Battery voltage is between 9-16 volts
* Ignition ON for 30 seconds
Conditions for Setting the DTC
* The damper coil or the circuits to the coil are shorted to ground, shorted to voltage, or open for 3 consecutive ignition ON cycles.
* The vehicle must be driven over 4.8 km/h (3 mph).
Action Taken When the DTC Sets
* The driver information center (DIC) displays a SERVICE RIDE CONTROL or SERVICE SUSPENSION SYSTEM message.
* If the DTC symptom 01 is stored, the electronic suspension control (ESC) system is disabled.
* If the DTC symptom 02 or 04 is stored, the suspect damper is disabled.
