DTC 9-7

DTC 9-7: Faulty Right Front Sensor

Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead H 07YAZ-S3M100

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. Check the connections between SRS unit connector C (18P) and the SRS unit, and between the front sensor wire harness 2P connector and the right front sensor.

Are the connections OK?

YES - Go to step 4.

NO - Repair the poor connections and retest. If DTC 9-7 still present, replace the right front sensor and retest. If the DTC is still present, replace the SRS unit.

4. Disconnect the battery negative cable, and wait for 3 minutes.




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




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




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




8. Disconnect the front sensor wire harness 2P connector (A) from the right front sensor.




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




10. Check resistance between the No.1 and No.12 terminals of SRS unit connector C (18P). There should be 1 MOhm or more.

Is the resistance as specified?

YES - Go to step 11.

NO - Short in the front sensor 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 the voltage between the No.1 terminal of SRS unit connector C (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 front sensor wire harness or the dashboard wire harness; replace the faulty harness.

14. Turn the ignition switch OFF.




15. Connect the special tool (jumper connector) to the front sensor wire harness 2P connector (A).




16. Check resistance between the No.1 and No.12 terminals of SRS unit connector C (18P). There should be 1 Ohm or less.

Is the resistance as specified?

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

NO - Faulty front sensor wire harness or the dashboard wire harness; replace the faulty harness.
