DTC 22-3x

DTC 22-3x(22-30 to 22-39, 22-3A to 22-3F): Short to Another Wire or Decreased Resistance in Front Passenger's Seat Belt Tensioner

Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead C107TAZ-SZ5011A
- SRS simulator lead F07XAZ-SZ30100

1. Erase the DTC memory.
2. Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and then goes off.

Does the SRS indicator slay on, and is DTC 22-3x indicated?

YES - Go to step 3.

NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. If another DTC is indicated, go to the DTC troubleshooting index.

3. Turn the ignition switch OFF. Disconnect the battery negative cable, and wait for 3 minutes.




4. Disconnect the front passenger's seat belt tensioner 2P connector from the right side subharness (A).
5. Connect the SRS inflator simulator (2 Ohm connectors) and the simulator lead C to the SRS right side subharness.
6. Reconnect the battery negative cable.
7. Erase the DTC memory.
8. Check for a DTC.

IS DTC 22-3x indicated?

YES - Go to step 9.

NO - Short in the front passenger's seat belt tensioner; replace the front passenger's seat belt.

9. Turn the ignition switch OFF. Disconnect the battery negative cable, and wait for 3 minutes.




10. Disconnect the SRS left side subharness 4P connector C806 (A) from the SRS right side subharness 4P connector C806 (B).
11. Connect the SRS inflator simulator (2 Ohm connectors) and the simulator lead F to the SRS left side subharness.
12. Reconnect the battery negative cable.
13. Erase the DTC memory.
14. Check for a DTC.

Is DTC 22-3x indicated?

YES - Go to step 15.

Is the resistance as specified?

YES - Faulty SRS unit; replace the SRS unit.

NO - Go to step 20.




20. Disconnect SRS left side subharness 28P connector C803 (A) from the SRS main subharness connector C803 (B).
