DTC 1-2

DTC 1-2: Increased Resistance In Driver's Airbag Inflator

Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- 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?

YES - Go to step 3.

NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures.

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




4. Disconnect the driver's airbag 4P connector (A) from the cable reel connector (B).
5. Connect the SRS inflator simulator (2 ohm connectors) and simulator lead F to the cable reel connector.
6. Reconnect the battery negative cable.
7. Erase the DTC memory.
8. Read the DTC.

Is DTC 1-1 or DTC 1-2 indicated?

YES - Go to step 9.

NO - Open or increased resistance in the driver's airbag inflator; replace the driver's airbag.

9. Turn the ignition switch OFF. Disconnect the battery negative cable, and wait for 3 minutes.
10. Disconnect the front passenger's airbag 4P connector from dashboard wire harness B.
11. Disconnect both seat belt tensioners 2P connectors from the floor wire harness.
12. Disconnect SRS unit connector A (18P) from the SRS unit. Do not disconnect the simulator lead from the cable reel connector.




13. Check resistance between the No. 7 and the No. 16 terminals and between the No. 6 and the No. 15 terminals of SRS unit connector A (18P). There should be 2.0 - 3.0 Ohm

Is the resistance as specified?

YES - Faulty SRS unit or poor contact at SRS unit connector A (18P) and the SRS unit, check the connection between the connector and the SRS unit. If the connection is OK, replace the SRS unit.

NO - Open or increased resistance in dashboard wire harness B or the cable reel; replace the cable reel. If the problem still present, replace dashboard wire harness B.
