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 (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 62-2x 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 front passenger's seat wire harness.

    Is there continuity? 

    YES  -Replace the front passenger's seat belt buckle assembly (see SEAT BELT BUCKLE ).

    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 Ω.

    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 MΩ.

    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. 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 Ω.

    Measure the resistance between the No. 1 and 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 9.

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

    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 (see FLOOR WIRE HARNESS (RIGHT BRANCH) ). 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 (see step  6 ).
  12. Disconnect SRS unit connector B (28P) from the SRS unit (see step  7 ).
  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 1M Ω.

    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 MΩ.
