DTC 45-1x

DTC 45-1x ("x" can be 0 thru 9 or A thru F): No Signal from the Left Side Impact Sensor (second)

Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead L 070AZ-SNAA300

NOTE: Before doing this troubleshooting procedure, review SRS Precautions and Procedures and General Troubleshooting Information.

1. Clear 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 step 4.

NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. Troubleshooting Intermittent Failures If another DTC is indicated, troubleshoot the DTC.

4. Read the DTC.

Is DTC 43-11 also indicated?

YES - Faulty left side impact sensor (second); replace the left side impact sensor (second).

NO - Go to step 5.

5. Read the DTC.

Is DTC B2-11 also indicated?

YES - Faulty rear safing sensor; Replace the rear safing sensor.

NO - Go to step 6.

6. Turn the ignition switch OFF.
7. Disconnect the negative cable from the battery, then wait for 3 minutes.
8. Disconnect floor wire harness 2P connector (A) from the left side impact sensor (second).






9. Disconnect the floor wire harness 4P connector (A) from the rear safing sensor.






10. Measure the 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 Mohms.






Is the resistance as specified?

YES - Go to step 11.

NO - Short in the floor wire harness; replace the floor wire harness.

11. Measure the 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 Mohms.






Is the resistance as specified?

YES - Go to step 12.

NO - Short to ground in the floor wire harness; replace the floor wire harness.

12. Reconnect the negative cable to the battery.
13. Turn the ignition switch ON (II).
14. Measure the 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 step 15.

NO - Short to power in the floor wire harness; replace the floor wire harness.

15. Turn the ignition switch OFF.
16. Connect the SRS inflator simulator (jumper connector) and the red lead (A) of simulator lead L to the rear safing sensor 4P connector (B).






17. Measure the resistance between the No. 1 and No. 2 terminals of left side impact sensor (second) 2P connector. There should be 0 - 1.0 ohm.






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).

NO - Open in the floor wire harness; replace the floor wire harness.
