DTC 43-1x (43-10 to 43-19, 43-1A to 43-1F): | No Signal from the Left Side Impact Sensor (first) |
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 43-11 indicated? YES - Go to 6. NO - Go to 4. |
4. | Read the DTC. Is DTC 43-12 indicated? YES - Go to 5. NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. If DTC 43-1x except DTC 43-11 and 43-12 is indicated, faulty left side impact sensor (first); replace the left side impact sensor (first).n |
5. | Read the DTC. Is DTC 45-11 indicated? YES - Faulty left side impact sensor (first); replace the left side impact sensor (first).n NO - Go to 6. |
6. | Turn the ignition switch OFF. |
7. | Disconnect the negative cable from the battery, and wait for 3 minutes. |
8. | Disconnect both seat belt outer lap tensioner 4P connectors. |
9. | Disconnect the floor wire harness 4P connector (A) from the left side impact sensor (first).
|
10. | Disconnect SRS unit connector B (28P) from the SRS unit. |
11. | Check resistance between the No. 25 and No. 26 terminals of SRS unit connector B (28P). There should be an open circuit or at least 1 MW.
Is the resistance as specified? YES - Go to 12. NO - Short in the floor wire harness; replace the floor wire harness.n |
12. | Check resistance between the No. 25 terminal of SRS unit connector B (28P) and body ground, and between the No. 26 terminal and body ground. There should be an open circuit or at least 1 MW.
Is the resistance as specified? YES - Go to 13. NO - Short to ground in the floor wire harness; replace the floor wire harness.n |
13. | Reconnect the negative cable to the battery. |
14. | Turn the ignition switch ON (II). |
15. | Check for voltage between the No. 25 terminal of SRS unit connector B (28P) and body ground, and between the No. 26 terminal and body ground. There should be 1 V or less.
Is the voltage as specified? YES - Go to 16. NO - Short to power in the floor wire harness; replace the floor wire harness.n |
16. | Turn the ignition switch OFF. |
17. | Connect the SRS inflator simulator (jumper connector) and simulator lead L to the left side impact sensor 4P connector (A).
|
18. | Check resistance between the No. 25 and No. 26 terminals of SRS unit connector B (28P). There should be 0-1.0 W.
Is the resistance as specified? YES - Faulty left side impact sensor (first) or SRS unit; replace the left side impact sensor (first). If the problem is still present, replace the SRS unit.n NO - Open in the floor wire harness; replace the floor wire harness.n |
