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 to occur:
- An intermittent open or short on the chassis pitch angle signal circuit.
- An intermittent open or short to ground on the serial data line.
- An intermittent short to ground or open on the chassis pitch angle signal 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 Chassis Pitch Angle while moving the wiring and the connectors. This can often cause the malfunction to appear.
- The scan tool can command the PCM to ground the chassis pitch input circuit. This can be used for diagnostic purposes.
