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.
- An internally open or shorted steering column lock relay may cause the column to not lock.
- An open on the key in ignition switch signal circuit will intermittently cause the column to not lock.
- Disconnecting or opening the steering column lock feedback circuit will cause the body control module (BCM) to enter a Fail Enable Standby mode. The steering column will remain inoperative until the Fail Enable Standby mode is cleared. To clear this mode, disconnect the BCM1 & instrument panel cluster (IPC) fuse in the instrument panel (I/P) fuse block for 15 seconds.
- Insure that a steering wheel theft deterrent lock shorting harness kit, or an aftermarket column lock bypass kit has not been installed.
