DTC 34-3x

DTC 34-3x (34-30 to 34-39, 34-3A to 34-3F): Short to Another Wire or Decreased Resistance in Right Side Curtain Airbag Inflator

Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead E 07XAZ-S1A0200
- SRS simulator lead F 07XAZ-SZ30100
- SRS short canceller 070AZ-SAA0100

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 stay on, and is DTC 34-3x 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 roof wire harness 2P connector (A) from the right side curtain airbag 2P connector (B).
5. Connect the SRS inflator simulator (2 Ohm connector) and the simulator lead E to the roof wire harness 2P connector.
6. Reconnect the battery negative cable.
7. Erase the DTC memory.
8. Check for a DTC.

Is DTC 34-3x indicated?

YES - Go to step 9.

NO - Short to another wire in the right side curtain airbag inflator; replace the right side curtain airbag.

9. Turn the ignition switch OFF. Disconnect the battery negative cable, and wait for 3 minutes.
10. Disconnect SRS main harness 4P connector C812 (A) from the roof wire harness 4P connector.




11. Connect the SRS inflator simulator (2 Ohm connectors) and the simulator lead F to the SRS main harness.
12. Reconnect the battery negative cable.
13. Erase the DTC memory.
14. Check for a DTC.

Is DTC 34-3x indicated?

YES - Go to step 15.

19. Check resistance between the No.3 and No.4 terminals of the SRS main harness 4P connector. 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 - Go to step 20.




20. Disconnect the SRS main:subharness 28P connector C801 (A) from SRS main harness C801 (B).
