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 less than 1.0 ohm.
Check resistance between the No. 1 and No. 2 terminals of the same connector. There should be an open circuit or at least 1 M ohm.
Are the resistances as specified?
YES - Go to step 7.
NO - Replace the driver's seat belt buckle assembly , then erase 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 less than 1.0 ohm.

Are the resistances as specified?
YES - Go to step 8.
NO - Replace the driver's seat belt buckle assembly then erase the DTC.
8. Check resistance between the No. 1 terminal of the driver's seat wire harness 3P connector or SRS harness 3P connector and body ground. There should be less than 1.0 ohm.
Is the resistance as specified?
YES - Go to step 9.
NO - Open in the driver's seat wire harness or SRS harness, or poor ground connection at G601 . If G601 is OK, replace the faulty harness.
9. Disconnect the negative cable from the battery.
10. Disconnect both seat belt tensioner2P 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. 3 terminal of the driver's seat wire harness 3P connector or SRS harness 3P connector. There should be less than 1.0 ohm.
Is the resistance as specified?
YES - Go to step 13.
NO - Open in the driver's seat wire harness, SRS harness, or SRS subharness replace the faulty harness.
13. Check resistance between the No. 11 terminal of SRS unit connector B (28P) and the No. 2 terminal of the driver's seat wire harness 3P connector or SRS harness 3P connector. There should be less than 1.0 ohm.
Is the resistance as specified?
YES - Replace the SRS unit.
NO - Open in the driver's seat wire harness, SRS harness, dashboard wire harness A, and/or SRS subharness replace the faulty harness.
