4. Turn the ignition switch OFF.
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. 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 front passenger's seat belt buckle assembly, then erase the DTC.
7. Unbuckle the front passenger's seat belt.
Check resistance between the No. 1 and No. 2 terminals of the front passenger'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.
Are the resistances as specified?
YES - Go to step 8.
NO - Replace the front passenger's seat belt buckle assembly, then erase the DTC.
8. Check for continuity between the No. 2 terminal of the front passenger's seat belt buckle switch 3P connector and body ground, and between the No. 3 terminal and body ground. There should be an open circuit or at least 1 MOhms.
Is the resistance as specified?
YES - Go to step 9.
NO - Replace the front passenger's seat belt buckle assembly.
9. Disconnect the battery negative cable, and wait for 3 minutes.
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 front passenger'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 front passenger's seat wire harness or floor wire harness; replace the faulty harness.
13. Disconnect the front passenger's seat belt tension reducer solenoid 2P connector. Check resistance between the No. 3 terminal of the front passenger'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 - Faulty SRS unit; replace the SRS unit.
NO - Short to ground in the front passenger's seat wire harness or floor wire harness; replace the faulty harness.
