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 in the suspension control switch circuit.
- An internal open or short in the suspension control switch.
- The ESC module uses an ignition cycle counter diagnostic approach to set this DTC. This requires the ESC module to detect the malfunction 4 times before setting the DTC. To disable this feature, use a scan tool to clear all DTCs before preforming diagnostic procedures.
- If the DTC is a history DTC, the problem may be intermittent. Using a scan tool, monitor the suspension control switch voltage while moving the wiring and the connectors. This can often cause the malfunction to appear.
