Circuit/System Testing

WARNING: This page is about a different car, the 2007 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector.
  • The information center telltale assembly indicator
  • The object alarm module
  • The rear information center telltale assembly indicator wiring harness connector
  • The object alarm module wiring harness connector
  1. Ignition ON, use the scan tool and perform the LED Test in Special Functions. The scan tool will command each indicator to turn ON then proceed to the next one.
  2. The rear information center telltale does turn ON then remove the rear information center telltale connector. Refer to information center telltale assembly replacement in Repair Instructions for connector location.
  3. Ignition ON, connect a test lamp between the telltale assembly supply voltage circuit and any indicator control circuit on the rear information center telltale indicator connector. With the scan tool perform the LED Test. Verify that the test lamp illuminates.
    • If the test lamp does not illuminate remove the object alarm module connector. Test all indicators and supply voltage circuits between the object alarm module connector and the information center telltale connector. If all circuits test normal then replace the information center telltale. After replacement refer to Repair Verification .
