Circuit/System Testing

WARNING: This page is about a different car, the 2006 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect all the LED indicator dimming supply circuit lamps related components. Refer to the circuit/system verification for all components that contain the LED indicator dimming supply circuit lamps. Verify the DTC B2625 does not set.
    • If the DTC resets then test for a short to ground in the LED indicator dimming supply circuit lamps circuit. If the circuit/connections test normal replace the BCM.
  2. Reconnect each component one at a time and test for the DTC B2625. If the DTC resets then replace that component.
