Seat Belt Latch: Testing and Inspection
1. Disconnect and isolate the battery negative cable. Disconnect the seat wire harness connector from the connector receptacle of the Seatbelt Control
Timer Module (SCTM).
2. Check the resistance between the inoperative (driver side or passenger side) seat belt solenoid control circuit cavity of the seat wire harness
connector for the SCTM and a good ground. The correct resistance should be from 50 to 60 ohms. If OK, refer to Seatbelt Control Timer Module
in the Diagnosis and Testing. If not OK, go to Step 3.
3. Disconnect the seat wire harness connector from the connector receptacle of the inoperative (driver or passenger) electric seat belt retractor latch
solenoid. Check the resistance between the two terminals in the connector receptacle of the electric seat belt retractor latch solenoid. The correct
resistance should be from 50 to 60 ohms. If OK, go to Step 4. If not OK, replace the faulty seat belt retractor unit.
4. Check the resistance between the ground circuit cavity of the seat wire harness connector for the electric seat belt retractor latch solenoid and a
good ground. There should be no measurable resistance. If OK, repair the open (driver side or passenger side) seat belt solenoid control circuit
between the seat wire harness connectors for the electric seat belt retractor latch solenoid and the SCTM as required. If not OK, repair the ground
circuit to ground as required.
