6. Turn the ignition switch OFF.
7. Disconnect the floor wire harness 3P connector from the driver's seat belt buckle switch 3P connector (A).
8. 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 Ohm.
Is the resistance as specified?
YES - Go to step 9.
NO - Replace the driver's seat belt buckle assembly, then clear the DTC.
9. Disconnect the negative cable from the battery, and wait for 3 minutes.
10. Disconnect both seat belt tensioner connectors and both seat belt buckle tensioner connectors.
11. Disconnect SRS unit connector B (28P) from the SRS unit.
12. Check resistance between the No. 12 terminal of SRS unit connector B (28P) and the No. 1 terminal of the floor wire harness 3P connector. There should be 0 - 1 Ohm.
Is the resistance as specified?
YES - Faulty SRS unit or poor connection at SRS unit connector B (28P) and the SRS unit. Check the connection between the connector and the SRS unit. If the connection is OK, replace the SRS unit.
NO - Open in the floor wire harness; replace the floor wire harness.
13. Turn the ignition switch OFF.
14. Disconnect the floor wire harness 3P connector from the driver's seat belt buckle switch 3P connector (A).
15. Unbuckle the driver's seat belt.
16. 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 Ohm.
Is the resistance as specified?
YES - Go to step 17.
NO - Replace the driver's seat belt buckle assembly, then clear the DTC.
17. Disconnect the negative cable from the battery, and wait for 3 minutes.
18. Disconnect the seat belt tensioner 4P connectors and both seat belt buckle tensioner 4P connectors.
19. Disconnect SRS unit connector B (28P) from the SRS unit.
20. Check resistance between the No. 11 terminal of SRS unit connector B (28P) and the No. 2 terminal of the floor wire harness 3P connector. There should be 0 - 1 Ohm.
Is the resistance as specified?
YES - Faulty SRS unit or poor connection at SRS unit connector B (28P) and the SRS unit. Check the connection between the connector and the SRS unit. If the connection is OK, replace the SRS unit.
NO - Open in the floor wire harness; replace the floor wire harness.
21. Turn the ignition switch OFF.
22. Disconnect the floor wire harness 3P connector from the driver's seat belt buckle switch 3P connector (A).
23. Unbuckle the driver's seat belt.
24. Check resistance between the No. 1 terminal of the floor wire harness 3P connector and body ground. There should be 0 - 1 Ohm.
Is the resistance as specified?
YES - Replace the driver's seat belt buckle assembly, then clear the DTC.
NO - Open in the floor wire harness or poor ground connection at G602:
- 2-door
- 4-door
If G602 is OK, replace the floor wire harness.
