| DTC 45-1x (45-10 to 45-19, 45-1A to 45-1F): | No Signal from the Left Side Impact Sensor (second) |
Special Tools Required
SRS inflator simulator ( 07SAZ-TB4011A)
| 1. | Erase the DTC memory. |
| 2. | Turn the ignition switch ON (II), and wait for 10 seconds. |
| 3. | Read the DTC. Is DTC 45-11 indicated? YES - Go to 5. NO - Go to 4. |
| 4. | Read the DTC. Is DTC 45-1x except 45-11 indicated? YES - Faulty left side impact sensor (second); replace the left side impact sensor (second).n NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. |
| 5. | Turn the ignition switch OFF. |
| 6. | Disconnect the negative cable from the battery, and wait for 3 minutes. |
| 7. | Disconnect the floor wire harness 2P connector (A) from the left side impact sensor (second).
|
| 8. | Disconnect the floor wire harness 4P connector (A) from the left side impact sensor (first).
|
| 9. | Check resistance between the No. 1 and No. 2 terminals of left side impact sensor (second) 2P connector. There should be an open circuit or at least 1 MW.
Is the resistance as specified? YES - Go to 10. NO - Short in the floor wire harness; replace the floor wire harness.n |
| 10. | Check resistance between the No. 1 terminal of left side impact sensor (second) 2P connector and body ground, and between the No. 2 terminal and body ground. There should be an open circuit or at least 1 MW.
Is the resistance as specified? YES - Go to 11. NO - Short to ground in the floor wire harness; replace the floor wire harness.n |
| 11. | Reconnect the negative cable to the battery. |
| 12. | Turn the ignition switch ON (II). |
| 13. | Check for voltage between the No. 1 terminal of left side impact sensor (second) 2P connector and body ground, and between the No. 2 terminal and body ground. There should be 1 V or less.
Is the voltage as specified? YES - Go to 14. NO - Short to power in the floor wire harness; replace the floor wire harness.n |
| 14. | Turn the ignition switch OFF. |
| 15. | Connect the SRS inflator simulator (jumper connector) and simulator lead M to the left side impact sensor (first) 4P connector (A).
|
| 16. | Check resistance between the No. 1 and No. 2 terminals of left side impact sensor 4P connector. There should be 0-1.0 W.
Is the resistance as specified? YES - Faulty left side impact sensor (second) or poor connection at left side impact sensor (second) 2P connector. Check the connection; if the connection is OK, replace the left side impact sensor (second).n NO - Open in the floor wire harness; replace the floor wire harness.n |
