| DTC 9-7: | Faulty Right Front Sensor |
Special Tools Required
SRS inflator simulator ( 07SAZ-TB4011A)
| 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 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 the U1o connector 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 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.n |
| 4. | Disconnect the battery negative cable, and wait for 3 minutes. |
| 5. | Disconnect the FSR1i connector (A) from the right front sensor.
|
| 6. | Disconnect the U1o connector (A) from the SRS unit.
|
| 7. | Check resistance between the No. 23 terminal and the No. 28 terminal of U1o connector. There should be 1 MW or more.
Is the resistance as specified? YES - Go to 8. NO - Short in the front sensor sub harness or dashboard wire harness; replace the faulty harness.n |
| 8. | Reconnect the battery negative cable. |
| 9. | Turn the ignition switch ON (ll). |
| 10. | Check for voltage between the No. 28 terminal of the U1o connector and body ground. There should be 1 V or less.

| 11. | Turn the ignition switch OFF. |
| 12. | Connect the special tool (jumper connector) to the FSR1i connector (A).
|
| 13. | Check resistance between the No. 23 and No. 28 terminals of U1o connector. There should be 2-3 W.
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.n NO - Faulty front sensor sub harness or dashboard wire harness; replace the faulty harness.n |
