Seat Belt Buckle Switch

Disconnect 4-pin driver-side seat belt buckle switch connector. Check for continuity between buckle switch 4-pin connector (component side) terminals No. 1 (Green/White wire) and No. 4 (White/Black wire). See WIRING DIAGRAMS . With belt fastened, continuity should exist. With belt unfastened, continuity should not exist. If continuity is not as specified, replace seat belt buckle switch and retest system operation.
