Test E: Security Indicator Inoperative: Testing

WARNING: This page is about a different car, the 2002 Pontiac Firebird, 2002 Chevrolet Camaro, 2001 Pontiac Firebird, and 2001 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.
  1. If theft deterrent diagnostic system check has been performed, go to next step. If theft deterrent diagnostic system check has not been performed, perform diagnostic system check before proceeding. See THEFT DETERRENT DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM.
  2. Connect scan tool to Data Link Connector (DLC). DLC is located below left side of instrument panel, to right of steering column. Turn ignition switch to RUN position. Using scan tool, command SECURITY indicator OFF. If SECURITY indicator does not turn off when commanded, go to next step. If SECURITY indicator turns off when commanded, inspect for intermittents or poor connections. See TROUBLE SHOOTING .
  3. Turn ignition switch to OFF position. Disconnect Instrument Panel Cluster (IPC) 34-pin harness connector. IPC is located behind instrument cluster. Connect a test light between ground and IPC harness connector terminal A10 (Orange wire). See Fig 1. Using scan tool, command SECURITY indicator ON. If test light does not illuminate, go to next step. If test light illuminates, go to step  6.
  4. Inspect Gray wire for an open or short to voltage between Body Control Module (BCM) harness connector C3 terminal C12 and IPC harness connector terminal B3. See Figure and Fig 1 . If an open or short to voltage is not found, go to next step. If an open or short to voltage is found, repair as necessary then go to step  9.
  5. Disconnect all BCM harness connectors. Inspect for corroded or pushed out pins. Connect all BCM harness connectors. Operate system and verify if concern still exists. If concern still exists, go to next step. If concern does not exist, go to step  9. Concern may have been caused by a loose or corroded connector.
  6. Disconnect all IPC harness connectors. Inspect for corroded or pushed out pins. Connect all IPC harness connectors. Operate system and verify if concern still exists. If concern still exists, go to next step. If concern does not exist, go to step  9. Concern may have been caused by a loose or corroded connector.
  7. Replace IPC. Program IPC. See INSTRUMENT PANEL CLUSTER  under PROGRAMMING. After replacement, go to step  9.
  8. Replace BCM. See BODY CONTROL MODULE  under PROGRAMMING. After replacement, go to next step.
  9. Operate system to verify repair. If system is not operating correctly, repeat test beginning at step  2.
