Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the information center telltale assembly.
  2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal A and ground.
    • If the test lamp does not illuminate, test the B+ circuit terminal for a short to ground or an open/high resistance. If the circuit tests normal, replace the object alarm module.
  3. Connect a test lamp between the B+ circuit terminal A and the appropriate control circuit listed below:
    • Amber 1 LED - terminal B
    • Amber 2 LED - terminal C
    • Red LED - terminal D
  4. Command the appropriate LED ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.
    • If the test lamp is always ON, test the control circuit for a short to ground. If the circuit tests normal, replace the object alarm module.
    • If the test lamp is always OFF, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the object alarm module.
  5. If all circuits test normal, test or replace the information center telltale assembly.
