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

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. Check for a 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 wire harness 3P connector (A) (with heated seat) or SRS harness 3P connector (A) (without heated seat) from the front passenger's seat belt buckle switch 3P connector (B).






6. Buckle 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 less than 1.0 ohm.

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 7.

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


7. Unbuckle 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 less than 1.0 ohm.

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. Disconnect the negative cable from the battery.
9. Disconnect both seat belt tensioner 2P connectors.
10. Disconnect SRS unit connector B (28P) from the SRS unit.
11. Measure the resistance between the No. 2 terminal of the front passenger's seat wire harness 3P connector or SRS 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 12.

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

12. Measure the resistance between the No.3 terminal of the front passenger's seat wire harness 3P connector or SRS 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 SRS harness or front passenger's seat wire harness; replace the faulty harness.
