DTC 61-2x
DTC 61-2x ("x" can be 0 thru 9 or A thru F): Short in Driver'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 driver's seat belt several times.
3. Check for a 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, troubleshoot the DTC.
4. Turn the ignition switch OFF.
5. Disconnect the driver's seat wire harness 3P connector (A) (with power seat) or the SRS harness 3P connector (A) (without power seat) from the driver's seat belt buckle switch 3P connector (B).
6. 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 less than 1.0 ohm.
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 Mohms.
Are the resistances as specified?
YES - Go to step 7.
NO - Replace the driver's seat belt buckle assembly, then clear the DTC.
7. 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 less than 1.0 ohm.
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 Mohms.
Are the resistances as specified?
YES - Go to step 8.
NO - Replace the driver's seat belt buckle assembly, then clear the DTC.
8. Disconnect the negative cable from the battery.
9. Disconnect both seat belt tensioner 2P connectors.
10. Disconnect SRS unit connector B (28P) from the SRS unit.
11. Remove the gauge control module. Disconnect gauge control module connector B from the gauge control module.
12. Measure the resistance between the No.2 terminal of the driver's seat wire harness 3P connector or SRS harness 3P connector and body ground. There should be an open circuit or at least 1 Mohms.
Is the resistance as specified?
YES - Go to step 13.
NO - Short to ground in the driver's seat wire harness, SRS harness, dashboard wire harness A and/or SRS subharness; replace the faulty harness.
13. Measure the resistance between the No.3 terminal of the driver's seat wire harness 3P connector or SRS harness 3P connector and body ground. There should be an open circuit or at least 1 Mohms.
Is the resistance as specified?
YES - Replace the SRS unit.
NO - Short to ground in the driver's seat wire harness, SRS harness, SRS subharness, or dashboard wire harness A; replace the faulty harness.
