DTC 46-1x

DTC 46-1x (46-10 to 46-19, 46-1A to 46-1F): No Signal from the Right Side Impact Sensor second)

Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead M 070AZ-SNA0400

1. Erase the DTC memory.
2. Turn the ignition switch ON (II), and 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. Diagnostic Strategies If another DTC is indicated, go to the DTC Troubleshooting Index. DTC List - Supplemental Restraint System

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 right side impact sensor second).




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




9. Check 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 MOhm.

Is the resistance as specified?

YES - Go to step 10.

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




10. Check 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 MOhm.

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. Check for 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. Check 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.
