DTC 61-2x
DTC 61-2x ("x" can be 0 thru 9 or A thru F): Short in Driver's Seat Belt Buckle Switch1. Erase the DTC memory.
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. Troubleshooting Intermittent Failures If another DTC is indicated, go to the DTC Troubleshooting Index. DTC List - Body Control System
4. Turn the ignition switch OFF.
5. Disconnect the driver's seat wire harness or floor wire harness 3P connector from the driver's seat belt buckle switch 3P connector (A).
6. Buckle the driver's seat belt.
Check resistance between the No. 1 and No. 3 terminals of the driver's seat belt buckle switch 3P connector. There should be 0 - 1 ohm.
Check resistance between the No. 2 and No. 3 terminals of the same connector. There should be an open circuit or at least 1 Mohm.
Are the resistances as specified?
YES - Go to step 7.
NO - Replace the driver's seat belt buckle assembly, then erase the DTC.
7. Unbuckle the driver's seat belt.
Check resistance between the No. 1 and No. 2 terminals of the driver's seat belt buckle switch 3P connector. There should be 0 - 1 ohm.
Check resistance between the No. 1 and No. 3 terminals of the same connector. There should be an open circuit or at least 1 Mohm.
Are the resistances as specified?
YES - Go to step 8.
NO - Replace the driver's seat belt buckle assembly, then erase the DTC.
8. Check resistance between the No. 2 terminal of the driver's seat belt buckle switch 3Pconnector and body ground, and between the No. 3 terminal and body ground. There should an open circuit or at least 1 Mohm.
Is the resistance as specified?
YES - Go to step 9.
NO - Replace the driver's seat belt buckle assembly.
9. Disconnect the negative cable from the battery.
10. Disconnect both seat belt tensioner 4P connectors from the floor wire harness.
11. Disconnect SRS unit connector B (28P) from the SRS unit.
12. Check resistance between the No. 2 terminal of the driver's seat wire harness or floor wire harness 3P connector and body ground. There should be an open circuit or at least 1 Mohm.
Is the resistance as specified?
YES - Check the connections at the floor wire harness, connector F (14P), and connector H (14P) at the driver's under-dash fuse/relay box. If the connections are OK, go to step 13.
NO - Short to ground in the driver's seat wire harness or floor wire harness, or the MICU/under-dash fuse/relay box. Replace the faulty harness or part.
13. Check resistance between the No. 3 terminal of the driver's seat wire harness or floor wire harness 3P connector and body ground. There should be an open circuit or at least 1 Mohm.
Is the resistance as specified?
YES - Faulty SRS unit; replace the SRS unit.
NO - Short to ground in the driver's seat wire harness or floor wire harness; replace the faulty harness.
