DTC 46-1x

DTC 46-1x ("x" can be 0 thru 9 or A thru F): No Signal from the Right 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), then wait for 10 seconds.
3. Read the DTC.

Is DTC 46-11 indicated?

YES - Go to step 5.

NO - Go to step 4.

4. Read the DTC.

Is DTC 46-12 also indicated?

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

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.

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






8. Disconnect the floor wire harness 4P connector (A) from the right side impact sensor (first).






9. Measure the resistance between the No. 1 and No. 2 terminals of right 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 10.

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

10. Measure the resistance between the No. 1 terminal of right 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 11.

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

11. Reconnect the negative cable to the battery.
12. Turn the ignition switch ON (II).
13. Measure the voltage between the No. 1 terminal of right 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 14.

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

14. Turn the ignition switch OFF.
15. Connect the SRS inflator simulator (jumper connector) and the red lead (A) of simulator lead L to the right side impact sensor (first) 4P connector (B).






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






Is the resistance as specified?

YES - Faulty right side impact sensor (second) or poor connection at right side impact sensor (second) 2P connector. Check the connection; If the connection is OK, replace the right side impact sensor (second).

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