Circuit/System Testing

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
  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.
