DTC 62-2x

DTC 62-2x ("x" can be 0 thru 9 or A thru F): Short in Front Passenger's Seat Belt Buckle Switch ('06-08 models)

NOTE: Before doing this troubleshooting procedure, review SRS Precautions and Procedures and General Troubleshooting Information.

1. Clear the DTC memory.
2. Turn the ignition switch ON (II), then buckle and unbuckle the front passenger's seat belt several times.
3. Read the DTC.

Is DTC 62-2x indicated?

YES - Go to step 4.

NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. Troubleshooting Intermittent Failures If another DTC is indicated, troubleshoot the DTC.

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. Measure the 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 no continuity.






Is there continuity?

YES - Replace the front passenger's seat belt buckle assembly.

NO - Go to step 7.

7. Buckle the front passenger's seat belt.

Measure the 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 ohms.

Measure the 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 8.

NO - Replace the front passenger's seat belt buckle assembly, then clear the DTC.

8. Unbuckle the front passenger's seat belt.

Measure the 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 ohms.

Measure the 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 9.

NO - Replace the front passenger's seat belt buckle assembly, then clear the DTC.

9. Measure the resistance between the No. 1 terminal of the front passenger's seat wire harness 3P connector and body ground. There should be 0-1 ohms.






Is the resistance as specified?

YES - Go to step 10.

NO - Open in the front passenger's seat wire harness or poor ground connection at G602. If G602 is OK, replace the floor wire harness.

10. Disconnect the negative cable from the battery, then wait for 3 minutes.
11. Disconnect both seat belt tensioner 4P connectors from the floor wire harness.
12. Disconnect SRS unit connector B (28P) from the SRS unit.
13. Measure the 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 14.

NO - Short to ground in the front passenger's seat wire harness; replace the faulty harness.

14. Measure the 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 - Replace the SRS unit.

NO - Short to ground in the front passenger's seat wire harness; replace the faulty harness.
