Seat Belt Buckle Switch
Disconnect seat belt buckle switch connector. Connector is located at bottom of inner seat belt. Check for continuity between seat belt buckle switch connector terminals. With seat belt fastened, continuity should be present. With seat belt unbuckled, continuity should not be present. If continuity is not as specified, replace seat belt buckle. Ensure continuity is present between terminal No. 1 of harness side of connector and ground. See Fig 1. Repair as necessary.
