DTC 9-6

DTC 9-6: Faulty Left Front Impact Sensor

Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead H 07YAZ-S3AA100

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. 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. Check the connections between SRS unit connector A (18P) and the SRS unit, between the engine compartment wire harness 2P connector and the left front impact sensor and at connector C403.

Are the connections OK?

YES - Go to step 4.

NO - Repair the poor connections and retest. If DTC 9-6 is still present, go to step 4.

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




5. Disconnect the driver's airbag 4P connector from the cable reel (A).




6. Disconnect the front passenger's airbag 4P connector from the dashboard wire harness (A).




7. Disconnect both seat belt tensioner 2P connectors from the floor wire harness (A).




8. Disconnect the engine compartment wire harness 2P connector (A) from the left front impact sensor.




9. Disconnect SRS unit connector A (18P) from the SRS unit.




10. Check resistance between the No. 10 and No. 11 terminals of SRS unit connector A (18P). There should be an open circuit or at least 1 MOhm.

Is the resistance as specified?

YES - Go to step 11.

NO - Short in the engine compartment wire harness or dashboard wire harness; replace the faulty harness.

11. Reconnect the battery negative cable.
12. Turn the ignition switch ON (II).




13. Check for voltage between the No. 10 terminal of SRS unit connector A (18P) and body ground. There should be 1 V or less.

Is the voltage as specified?

YES - Go to step 14.

NO - Short to power in the engine compartment wire harness or the dashboard wire harness; replace the faulty harness.

14. Turn the ignition switch OFF.




15. Connect the SRS inflator simulator (jumper connector) and the simulator lead H to the engine compartment wire harness 2P connector (A).




16. Check resistance between the No. 10 and No. 11 terminals of SRS unit connector A (18P). There should be 1 Ohm or less.

Is the resistance as specified?

YES - Faulty left front impact sensor or SRS unit. Replace the left front impact sensor; if the problem is still present, replace the SRS unit

NO - Faulty engine compartment wire harness or dashboard wire harness; replace the faulty harness.
