5. Disconnect the floor wire harness 3P connector from the driver's seat belt buckle switch 3P connector (A).




6. Buckle the driver's seat belt.

Check resistance between the No.1 and No.3 terminals of the driver's seat belt buckle switch 3P connector. There should be 0 - 1 Ohms.

Check resistance between the No.2 and No.3 terminals of the same connector. There should be an open circuit, or at least 1 MOhms.

Are the resistance readings as specified?

YES - Go to step 7.

NO - Replace the driver's seat belt buckle assembly, then clear the DTC.




7. Unbuckle the driver's seat belt.

Check resistance between the No.1 and No.2 terminals of the driver's seat belt buckle switch 3P connector. There should be 0 - 1 Ohms.

Check resistance between the No.1 and No.3 terminals of the same connector. There should be an open circuit, or at least 1 MOhms.

Is the resistance as specified?

NO - Replace the driver's seat belt buckle assembly, then clear the DTC.




8. Check resistance between body ground and driver's seat belt buckle switch 3P connector terminals No.2 and No.3. There should an open circuit or at least 1 MOhms.

Is the resistance as specified?

YES - Go to step 9.

NO - Replace the driver's seat belt buckle assembly.

9. Disconnect the negative cable from the battery.
10. Disconnect both seat belt tensioner 4P connectors from the floor wire harness.
11. Disconnect SRS unit connector B (28P) from the SRS unit.




12. Check resistance between the No.2 terminal of the floor wire harness 3P connector and body ground. There should be an open circuit, or at least 1 MOhms.

Is the resistance as specified?

YES - Check the connections at the floor wire harness, connector F (14P), and connector H (14P) at the under-dash fuse/relay box. If the connections are OK, go to step 13.

NO - Short to ground in the floor wire harness or the multiplex control unit. Replace the faulty harness or part.




13. Check resistance between the No 3 terminal of the floor wire harness 3P connector and body ground. There should be an open circuit, or at least 1 MOhms.

Is the resistance as specified?

YES - Replace the SRS unit.

NO - Short to ground in the floor wire harness; replace the floor wire harness.
