DTC 34-9x

DTC 34-9x (34-90 to 34-99, 34-9A to 34-9F): Short to Ground in Right Side Curtain Airbag Inflator

Special Tools Required
- SRS inflator simulator 075AZ-TB4011A
- SRS simulator lead E 07XAZ-51A0200
- SRS simulator lead F 07XAZ-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 stay on, and is DTC 34-9x 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 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 34-9x indicated?

YES - Go to step 9.

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