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 07XA2-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. Diagnostic Strategies If another DTC is indicated, go to the DTC Troubleshooting Index. DTC List - Supplemental Restraint System

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




4. Disconnect the right side curtain airbag 2P connector (A) from the roof wire harness (B).
5. Connect the SRS inflator simulator (2 Ohms connector) and simulator lead E to the roof wire harness.
6. Reconnect the battery negative cable.
7. Erase the DTC memory.
8. Read the 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 floor wire harness 4P connector C501 (A) from the roof wire harness connector C501 (B).
11. Connect the SRS inflator simulator (2 Ohms connectors) and simulator lead F to the floor wire harness.
12. Reconnect the battery negative cable.
13. Erase the DTC memory.
14. Read the DTC.

Is DTC 34-3x indicated?

YES - Go to step 15.

16. Disconnect SRS unit connector C (28P) from the SRS unit.
17. Disconnect the SRS inflator simulator from the SRS simulator lead F.
18. Connect the SRS short canceller (070AZ-SAA0100) to the No. 9 and No. 10 terminals of SRS unit connector C (28P).




19. Check resistance between the terminals of both SRS simulator leads. There should be an open circuit or at least 1 MOhm.

Is the resistance as specified?

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

NO - Short to another wire in the floor wire harness; replace the floor wire harness.
