  1. Turn ignition on. Using scan tool, select KEY-IN-IGNITION SWITCH. Cycle ignition on and off while observing scan tool display. If scan tool display does not match actual ignition switch position, go to next step. If scan tool display matches actual ignition switch position, problem is intermittent. Check for poor connection to BCM or at ignition switch. See COMPONENT LOCATIONS . Repair as necessary and retest operation.

Connect DVOM between ground and Gray 24-pin BCM connector J2 terminal A11 (Light Green wire). See Figure. If continuity exists with key in ignition switch, go to next step. If continuity does not exist with key in ignition switch, go to step  4.
  3. Check for poor connection to BCM. Repair as necessary and retest operation. If BCM connection checks okay, replace BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION. Retest operation.
  4. Check for open in Light Green wire between Gray 24-pin BCM connector J2 terminal A11 and ignition switch, open in ignition switch, open in ground circuit or poor connections at ignition switch. See WIRING DIAGRAMS . Repair as necessary and retest operation.
