DTC 34-21

DTC 34-11: Open in Right Side Curtain Airbag Inflator

DTC 34-21: Increased Resistance in Right Side Curtain Airbag Inflator

Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead E 07XAZ- S1A0200

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 34-11 or 34-21 indicated?

YES - Go to step 3.

NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. Initial Inspection and Diagnostic Overview If another DTC is indicated, go to the DTC Troubleshooting Index. Diagnostic Trouble Code Descriptions

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




4. Disconnect the right side wire harness 2P connector (A) from the right side curtain airbag (B).
5. Connect the SRS inflator simulator (2 Ohms connector) and simulator lead E to the right side wire harness,
6. Reconnect the negative cable to the battery.
7. Erase the DTC memory.
8. Read the DTC.

Is DTC 34-11 or 34-21 indicated?

YES - Go to step 9.

NO - Open or increased resistance in the right side curtain airbag inflator, replace the right side curtain airbag.

9. Turn the ignition switch OFF. Disconnect the negative cable from the battery, and wait for 3 minutes.
10. Disconnect SRS unit connector C (28P) from the SRS unit.
11. Disconnect the SRS inflator simulator from the SRS simulator lead.




12. Check resistance between the terminals of the SRS simulator lead. There should be 1.0 Ohm or less.

Is the resistance as specified?

YES - Faulty SRS unit or poor connection at SRS unit connector C (28P) and SRS unit. Check the connection; if the connection is OK, replace the SRS unit.

NO - Go to step 13.




13. Disconnect right side wire harness 16P connector C655 (A) from left side wire harness connector C655 (B).




14. Check resistance between the No. 11 and No. 12 terminals of the left side wire harness 16P connector C655. There should be 1.0 Ohm or less.

Is the resistance as specified?

YES - Open or increased resistance in the right side wire harness; replace the right side wire harness.

NO - Go to step 15.




15. Disconnect right side wire harness 16P connector C604 (A) from left side wire harness connector C604 (B).




16. Check resistance between the No. 11 [No. 6] and No. 12 [No. 8] terminals of the right side wire harness 16P connector C604. There should be 1.0 Ohm or less.
[] :06 Model

Is the resistance as specified?
