Circuit/System Testing

WARNING: This page is about a different car, the 2007 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 seat position sensor
    • The SDM module
    • The seat position sensor wiring harness connector
    • The SDM wiring harness connector
  1. Ignition OFF, if DTC B0080 is current, disconnect the right SPS connector. Refer to POWER SEATS seat position sensor replacement in Repair Instructions for location of connector.
  2. Remove the SDM connector. Refer to Inflatable Restraint Sensing and Diagnostic Module Replacement (AG1/AG2)  or Inflatable Restraint Sensing and Diagnostic Module Replacement (AM6)  in Repair Instructions for connector location.
  3. Test the low reference and signal circuits between the SDM and SPS. 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 SIR components. Ignition ON, use the scan tool to clear the DTCs then recheck for DTCs. Verify DTC B0080 does not set.
    • If DTC B0080 was current, replace the right SPS. After replacement, refer to Repair Verification below.
