DTC 61-2x ("x" can be 0 thru 9 or A thru F): Short in Driver'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 driver's seat belt several times.
  3. Read the DTC.

    Is DTC 61-2x 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 driver's seat harness 3P connector from the driver's seat belt buckle switch 3P connector (A).

    Is there continuity? 

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

    NO  -Go to step 7.

  7. Buckle the driver's seat belt.

    Measure the resistance between the No. 1 and No. 3 terminals of the driver'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 M Ω.

    Are the resistances as specified? 

    YES  -Go to step 8.

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

  8. Unbuckle the driver's seat belt.

    Measure the resistance between the No. 1 and No. 2 terminals of the driver'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 1 M Ω.

    Are the resistances as specified? 

    YES  -Go to step 9.

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

  9. Measure the resistance between the No. 1 terminal of the driver'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 driver's seat wire harness or floor wire harness, or poor ground connection at G601 (see FLOOR WIRE HARNESS (LEFT BRANCH) ). If G601 is OK, replace the faulty 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 driver's seat wire harness 3P connector and body ground. There should be an open circuit or at least 1MΩ.

    Is the resistance as specified? 

    YES  -Go to step 14.

    NO  -Short to ground in the driver's seat wire harness, floor wire harness, or multiplex integrated control unit. Replace the faulty harness or part.

  14. Measure the resistance between the No. 3 terminal of the driver's seat wire harness 3P connector and body ground. There should be an open circuit or at least 1MΩ.

    Is the resistance as specified? 

    YES  -Replace the SRS unit (see SRS UNIT REPLACEMENT  ).

    NO  -Short to ground in the driver's seat wire harness or floor wire harness; replace the faulty harness.
