Diagnostic Aids
WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
- The following conditions may cause an intermittent malfunction:
- There is an intermittent open or short to ground in a battery 1 or battery 2 circuit.
- The battery voltage is out of range.
- A charging system malfunction.
- Using a scan tool, select DCM Data display and monitor battery 1 and battery 2 voltage while operating the door locks and heated mirrors. This can determine if battery 1 or battery 2 voltage is affected by these devises and can help duplicate the malfunction.
- If the DTC does not reset after the code is cleared, then the problem may be intermittent. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
