Circuit/System Verification

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify the appropriate DTC is not set.
    • If the DTC is set along with other codes, diagnose all other codes first. If no other codes are set, program the control module specified by the DTC descriptor.
  2. With a scan tool, clear the DTCs.
  3. Ignition OFF, remove the scan tool, open and close the drivers door.
  4. Wait 60 seconds, then verify the DTC is not set.
    • If the DTC is set, replace the appropriate control module.
