5. Disconnect the front passenger's seat belt buckle switch 3P connector (A) from the front passenger's seat wire harness.
6. Buckle the front passenger's seat belt.
- Check resistance between the No. 1 and No. 3 terminals of the front passenger's seat belt buckle switch 3P connector. There should be 0 - 1 ohm.
- Check resistance between the No. 2 and No. 3 terminals of the same connector. There should be an open circuit or at least 1 Mohm.
Are the resistances as specified?
YES - Go to step 7.
NO - Replace the front passenger's seat belt buckle assembly, then clear the DTC.
7. Unbuckle the front passenger's seat belt.
- Check resistance between the No. 1 and No. 3 terminals of the front passenger's seat belt buckle switch 3P connector. There should be 0 - 1 ohm.
- Check resistance between the No. 2 and No. 3 terminals of the same connector. There should be an open circuit or at least 1 Mohm.
Are the resistances as specified?
YES - Go to step 8.
NO - Replace the front passenger's seat belt buckle assembly, then clear the DTC.
8. Check resistance between the No. 3 terminal of the front passenger's seat wire harness 3P connector and body ground. There should be 0 - 1 ohm.
Is the resistance as specified?
YES - Go to step 9.
NO - Open in the front passenger's seat wire harness or right side wire harness, or poor ground connection at G651. If G651 is OK, replace the faulty harness.
9. Disconnect the negative cable from the battery, and wait for 3 minutes.
10. Disconnect both seat belt tensioner 4P connectors from the left side wire harness and right side wire harness.
11. Disconnect SRS unit connector B (28P) from the SRS unit.
12. Check resistance between the No. 16 terminal of SRS unit connector B (28P) and the No. 1 terminal of the front passenger's seat wire harness 3P connector. There should be 0 - 1 ohm.
Is the resistance as specified?
YES - Go to step 13.
NO - Open in the front passenger's seat wire harness or right side wire harness; replace the faulty harness.
13. Check resistance between the No. 15 terminal of SRS unit connector B (28P) and the No. 2 terminal of the front passenger's seat wire harness 3P connector. There should be 0 - 1 ohm.
Is the resistance as specified?
YES - Faulty SRS unit; replace the SRS unit.
