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.
IMPORTANT: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector.
  • The external speaker
  • The object alarm module
  • The external speaker wiring harness connector
  • The object alarm module wiring harness connector
  1. Ignition OFF, if DTC B0953 is current, disconnect the external speaker connector.
  2. Remove the object alarm module connector. Refer to Object Alarm Module Replacement  in Repair Instructions for connector location.
  3. Test both speaker circuits between the object alarm module and the speaker. Verify that a short to voltage, short to ground or open/low resistance does not exist.
    • If any of the above conditions are found make the appropriate repair.
  4. Reconnect all components. Ignition ON, use the scan tool to clear the DTCs then recheck for DTCs. Verify DTC B0953 does not set.
