DTC 33-11

DTC 33-11: Open in Left Side Curtain Airbag Inflator

DTC 33-21: Increased Resistance in Left 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 33-11 or 33-21 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 left side wire harness 2P connector (A) from the left side curtain airbag (B).
5. Connect the SRS inflator simulator (2 Ohms connector) and simulator lead E to the left side wire harness.
6. Reconnect the negative cable to the battery.
7. Erase the DTC memory.
8. Read the DTC.

Is DTC 33-11 or 33-21 indicated?

YES - Go to step 9.

NO - Open or increased resistance in the left side curtain airbag inflator; replace the left side curtain airbag.

9. Turn the ignition switch OFF. Disconnect the negative cable from the battery, and wait for 3 minutes.
10. Disconnect the SRS unit connector C (28P) from the SRS unit.
11. Disconnect the SRS inflator simulator from 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 the 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 from left side wire harness connector C655.




14. Check resistance between the No. 6 and No. 8 terminals of the right 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 left side wire harness; replace left side wire harness.

NO - Open or increased resistance in the right side wire harness; replace the right side wire harness.
