2. Turn the ignition switch ON (II), then buckle and unbuckle the left side seat belt several times.
3. Read the DTC.
Is DTC 61-11 indicated?
YES - Go to step 4.
NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. Initial Inspection and Diagnostic Overview If another DTC is indicated, go to the DTC Troubleshooting Index. Diagnostic Trouble Code Descriptions
4. Turn the ignition switch OFF.
5. Disconnect the left side wire harness or the driver's seat wire harness 3P connector from the driver's seat belt buckle switch 3P connector (A).
6. Buckle the driver's seat belt.
- Check resistance between the No. 1 and No. 3 terminals of the left side 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 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. 2 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. 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 driver's seat belt buckle assembly, then clear the DTC.
8. Check resistance between the No. 3 terminal of the driver'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 driver's seat wire harness or left side wire harness.or poor ground connection at G601. lfG601 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. 12 terminal of SRS unit connector B (28P) and the No. 1 terminal of the driver'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 driver's seat wire harness or left side wire harness; 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. There should be 0-1 Ohm.
Is the resistance as specified?
YES - Faulty SRS unit; replace the SRS unit.
NO - Open in the driver's seat wire harness, left side wire harness, or the driver's under-dash fuse/relay box, or poor connection at the left side wire harness. Check the connection at the left side wire harness and the driver's under-dash fuse/relay box. If the connection is OK, replace the faulty harness or part.
