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 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 MOhms.
Are the resistances 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 Ohm.
- 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?
YES - Go to step 8.
NO - Replace the driver's seat belt buckle assembly, then clear the DTC.
8. Disconnect the negative cable from the battery.
9. Disconnect both seat belt tensioner 2P connectors.

11. Remove the gauge assembly. Disconnect gauge assembly connector A from the gauge assembly.
12. Check resistance between the No. 2 terminal of the driver's seat wire harness 3P connector and body ground. There should be an open circuit or at least 1 MOhms.
Is the resistance as specified?
YES - Go to step 13.
NO - Short to ground in the driver's seat wire harness, SRS floor harness, or dashboard wire harness A. Replace the faulty harness.
13. Check resistance between the No. 3 terminal of the driver's seat 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 left floor wire harness or SRS floor harness; replace the faulty harness.
