DTC 62-1x ("x" can be 0 thru 9 or A thru F): Open in Front Passenger's Seat Belt Buckle SwitchNOTE: 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 62-1x indicated?
YES - Go to step 4.
NO - Intermittent failure, the system is OK at this time. Go to Troubleshooting Intermittent Failures. Troubleshooting Intermittent Failures If another DTC is indicated, troubleshoot the DTC.
4. From the system selection menu on the HDS, select SRS, then select SRS again, then select PARAMETER INFORMATION, then Buckle Switch, Seat Position Sensor and check the status on the HDS screen for FRONT RIGHT SEAT BELT BUCKLE SWITCH.
- If UNBUCKLED is indicated only when the front passenger's seat belt is buckled, go to step 5.
- If BUCKLED is indicated only when the front passenger's seat belt is unbuckled, go to step 12.
- If OPEN is indicated only when the front passenger's seat belt is buckled and unbuckled, go to step 20.
5. Turn the ignition switch OFF.
6. Disconnect the ODS unit harness 3P connector from the front passenger's seat belt buckle switch 3P connector (A).
7. 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.
Is the resistances specified?
YES - Go to step 8.
NO - Replace the front passenger's seat belt buckle assembly, then erase the DTC.
8. Disconnect the negative cable from the battery, then wait for 3 minutes.
9. Disconnect both seat belt tensioner connectors and both seat belt buckle tensioner connectors.
10. Disconnect SRS unit connector B (28P) from the SRS unit.
11. Measure the resistance between the No. 16 terminal of SRS unit connector B (28P) and the No. 1 terminal of the ODS unit harness 3P connector. There should be 0-1 ohm.
Is the resistance as specified?
YES - Faulty SRS unit or poor connection at SRS unit connector B (28P) and the SRS unit. Check the connection between the connector and the SRS unit. If the connection is OK, replace the SRS unit.
NO - Open in the SRS wire harness, ODS unit harness or poor connection at C703. Check the connection; if the connection is OK, replace the faulty harness.
12. Turn the ignition switch OFF.
13. Disconnect the ODS unit harness 3P connector from the front passenger's seat belt buckle switch 3P connector (A).
14. Unbuckle the front passenger's seat belt.
15. Measure the resistance between the No. 2 and No. 3 terminals of the front passenger's seat belt buckle switch 3P connector. There should be 0-1 ohm.
Is the resistance as specified?
YES - Go to step 16.
NO - Replace the front passenger's seat belt buckle assembly, then clear the DTC.
16. Disconnect the negative cable from the battery, then wait for 3 minutes.
17. Disconnect both seat belt tensioner 4P connectors and both seat belt buckle tensioner 4P connectors.
18. Disconnect SRS unit connector B (28P) from the SRS unit.
19. Measure the resistance between the No. 15 terminal of SRS unit connector B (28P) and the No. 2 terminal of the ODS unit harness 3P connector. There should be 0-1 ohm.
Is the resistance as specified?
YES - Faulty SRS unit or poor connection at SRS unit connector B (28P) and the SRS unit. Check the connection between the connector and the SRS unit. If the connection is OK, replace the SRS unit.
NO - Open in the SRS wire harness, ODS unit harness or poor connection at C703. Check the connection; if the connection is OK, replace the faulty harness.
20. Turn the ignition switch OFF.
21. Disconnect the ODS unit harness 3P connector from the front passenger's seat belt buckle switch 3P connector (A).
22. Unbuckle the front passenger's seat belt.
23. Measure the resistance between the No. 3 terminal of the ODS unit harness 3P connector and body ground. There should be 0-1 ohm.
Is the resistance as specified?
YES - Replace the front passenger's seat belt buckle assembly, then clear the DTC.
NO - Open in the SRS wire harness, ODS unit harness, poor connection at C703 and poor ground connection at G552. C703 and G552 connection is OK, replace the faulty harness.
