NOTE: This symptom is defined as system operates normally, but goes into alarm mode intermittently without alarm input trigger.
  1. Perform BCM SYSTEM CHECK in BODY CONTROL MODULE article.
  2. Check shock sensor sensitivity. See PROGRAMMING  . If sensitivity is okay, go to next step. If sensitivity is not okay, adjust as necessary. After adjustment, go to step 5).
  3. Ensure instrument panel dimmer switch is off. Turn on interior light override switch (interior lights enabled, not on). Turn ignition on. Close all doors. While observing interior lights, tap gently on inside door panels, near door latches. If interior lights stay off, go to next step. If interior lights illuminate, repair problem between door ajar switch and BCM. See WIRING DIAGRAMS  . After repairs, go to step 5).
  4. Disconnect shock sensor connector. Disconnect BCM connector C2. Using DVOM, check continuity between BCM harness connector C2 terminal D14 (Light Green wire) and ground. If continuity does not exist, problem does not exist at this time. If continuity exists, repair short to ground in Light Green wire. After repairs, go to next step.
  5. Turn ignition off. Reinstall all connectors and components. Turn ignition to RUN for 6 seconds. Turn ignition off. Remove BCM PRGRM fuse. Turn ignition to ACC. BCM should flash seat belt indicator and sound chime 4 times. Within one second, turn ignition from ACC to LOCK, then back to ACC. If any DTCs are stored, see BODY CONTROL MODULE S article. If BCM DTCs do not exist, system is okay.
