Diagnostic Aids

WARNING: This page is about a different car, the 2000 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
  1. The following conditions may cause an intermittent:
    • Intermittent short to voltage in Black wire between BCM and foglight/rear compartment lid/hatch release switch.
    • Foglight/rear compartment lid/hatch release switch sticking or internally shorted to voltage.
    • Foglight/rear compartment lid/hatch release switch is pressed for longer than 60 seconds.
  2. If short to voltage occurs in Black wire between BCM and foglight/rear compartment lid/hatch release switch when ignition is on, rear hatch will release once and then remain inoperative. If short to voltage occurred when ignition is off, rear hatch will release when ignition is turned on and then remain inoperative. BCM will retain information of last transition, and will not release rear hatch again until it received a change from foglight/rear compartment lid/hatch release switch.
