Diagnostic Aids
- The following conditions may cause an intermittent malfunction:
- An intermittent open circuit condition on the steering position sensor circuit.
- A short to ground or to voltage in the steering position sensor circuit.
- Intermittent operation of the EBCM.
- If the CVRSS module does not receive a valid steering position signal from the EBCM, the CVRSS system will still function, but will ignore the steering position signal. The CVRSS 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 circuit condition to ground or voltage on the steering position sensor circuit may 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.
