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.
