DTC 62-1 x ("x" can be 0 thru 9 or A thru F): Open in Front Passenger's Seat Belt Buckle Switch ('04-05 models)

NOTE: Before doing this troubleshooting procedure, review SRS Precautions and Procedures (see PRECAUTIONS AND PROCEDURES  ) and General Troubleshooting Information (see DTC (DIAGNOSTIC TROUBLE CODES)  ).
  1. Clear the DTC memory (see CLEAR THE DTC MEMORY WITH THE HDS  ).
  2. Turn the ignition switch ON (II), then buckle and unbuckle the front passenger's seat belt several times.
  3. Read the DTC (see DTC (DIAGNOSTIC TROUBLE CODES)  ).

    Is DTC 62-1x indicated? 

    YES  -Go to step 4.

    NO  -Intermittent failure, system is OK at this time. Go to 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 floor wire harness ('04 model) or front passenger's seat wire harness ('05 model).

  6. 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 Ω.

    Measure the resistance between the No. 1 [No. 2] and No. 2 [No. 3] terminals of the same connector. There should be an open circuit or at least 1MΩ.

    Are the resistances as specified? 

    YES  -Go to step 7.

    NO  -Replace the front passenger's seat belt buckle assembly (see SEAT BELT BUCKLE ), then clear the DTC.

  7. Unbuckle the front passenger's seat belt.

    Measure the resistance between the No. 1 [No. 2] and No. 2 [No. 3] terminals of the front passenger's seat belt buckle switch 3P connector. There should be 0-1 Ω.

    Are the resistances as specified? 

    YES  -Go to step 8.

    NO  -Replace the front passenger's seat belt buckle assembly (see SEAT BELT BUCKLE ), then clear the DTC.

  8. Measure the resistance between the No. 1 [No. 3] terminal of the floor wire harness 3P connector and body ground. There should be 0-1 Ω.

    Is the resistance as specified? 

    YES  -Go to step 9.

    NO  -Open in the floor wire harness, front passenger's seat wire harness ('05 model) or poor ground connection at G602 (see FLOOR WIRE HARNESS (RIGHT BRANCH) ). If G602 is OK, replace the faulty harness.

  9. Disconnect the negative cable from the battery, then wait for 3 minutes.
  10. Disconnect both seat belt tensioner 4P connectors from the floor wire harness (see step  6 ).
  11. Disconnect SRS unit connector B (28P) from the SRS unit (see step  7 ).
  12. Measure the resistance between the No. 18 terminal of SRS unit connector B (28P) and the No. 3 [No. 1] terminal of the floor wire harness 3P connector. There should be 0-1 Ω.
