Circuit/System Testing

WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, park lamps OFF, disconnect all the LED indicator dimming supply circuit lamp components on the circuit. Verify DTC B2625 does not set.
    • If the DTC resets, test for a short to voltage, short to ground, or an open in the LED indicator dimming supply voltage circuit. If the circuit/connections test normal, replace the BCM, driver door switch, and passenger door switch as applicable.
  2. Reconnect each component one at a time and test for the DTC B2625.
    • If the DTC resets, replace that particular component.
