DTC 1-3

DTC 1-3: Short to Another Wire or Decreased Resistance in Driver's Airbag Inflator

Special Tools Required
- SRS inflator simulator 07SA2-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.
5. Connect the simulator lead F (2 Ohms connectors) and the inflator simulator to the cable reel 4P connector.
6. Reconnect the battery negative cable.
7. Erase the DTC memory.
8. Read the DTC.

Is DTC 1-3 indicated?

YES - Go to step 9

NO - Short in the driver's airbag; replace the driver's airbag.

9. 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 tensioner 2P connectors from the floor wire harness.
12. Disconnect SRS unit connector A (18P) from the SRS unit.
13. Disconnect the simulator lead from the cable reel 4P connector.




14. 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 an open circuit or at least 1 MOhm.

Is the resistance as specified?

YES - Faulty SRS unit; replace the SRS unit.

NO - Go to step 15.

15. Disconnect the cable reel from dashboard wire harness B. 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 an open circuit or at least 1 MOhm.

Is the resistance as specified?

YES - Replace the cable reel.

NO - Replace dashboard wire harness B.
