C0710

Circuit Description
The Electronic Suspension Control Module receives a PWM steering position signal from the Electronic Brake Control Module (EBCM). The Electronic Suspension Control Module monitors the PWM steering position circuit to determine if a valid signal is sent from the EBCM.

Conditions for Running the DTC
^ The ignition is on.
^ The fault is detected during three consecutive ignition cycles, or during the same ignition cycle after clearing the DTC using the scan tool.

Conditions for Setting the DTC
The Electronic Suspension Control Module does not detect a valid steering position signal from the EBCM for 5.0 seconds.

Action Taken When the DTC Sets
^ The Electronic Suspension Control Module will ignore the steering position signal input.
^ The Electronic Suspension Control Module will continue to control the shock absorbers using the lateral acceleration data sent from the EBCM on the serial data line.
^ The SERVICE RIDE CONTROL message is displayed.

Conditions for Clearing the MIL/DTC
^ The scan tool can be used to clear the DTC.
^ The On-Board diagnostics CLEAR RSS CODES feature can be used to clear the DTC.
^ The DTC is saved as history when the Electronic Suspension Control Module detects a valid steering position signal from the EBCM. The DTC will clear if the fault does not return after 50 consecutive ignition cycles.

Diagnostic Aids
^ The following conditions will cause an intermittent malfunction:
- An intermittent open circuit condition in the steering position sensor circuit.
- A short to ground or to voltage in the steering position sensor circuit.
- Intermittent operation of the Electronic Brake Control Module (EBCM).
^ If the Electronic Suspension Control Module does not receive a valid steering position signal from the EBCM, the Electronic Suspension Control system will still function, but will ignore the steering position signal. The Electronic Suspension Control system uses lateral acceleration data sent from the EBCM on the serial data line in order to substitute for a loss of the steering position signal.
^ An intermittent open circuit condition, or a short to ground or voltage on the steering position sensor circuit will cause a random firm/soft ride condition.
^ If the DTC is a history DTC, the problem may be intermittent. Using a scan tool, monitor the steering position sensor circuit while moving the related wiring and connectors. This can often cause the malfunction to appear.
