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 short to ground in the folding top release switch signal circuit.
- The folding top switch is shorted to ground internally or is sticking.
- The folding top switch is pressed for longer than 60 seconds.
- If the folding top release switch signal circuit is shorted to ground with the ignition ON, the folding top will release once and then will remain inoperative. If the short occurred when the ignition was turned OFF, the folding top will release as soon as the ignition is turned ON and then will remain inoperative. The BCM will remember the last transition that took place from the folding top release switch and will not release the folding top again until the BCM detects a change from the folding top switch.
- If the DTC is a history DTC, the problem may be intermittent. Perform the tests shown while moving related wiring and connectors. This can often cause the malfunction to occur. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
