DTC 44-1x

DTC 44-1x (44-10 to 44-19, 44-1A to 44-1F): No Signal from Right side Impact Sensor

Special Tools Required
- SRS inflator simulator 07SAZ-TB4011A
- SRS simulator lead H 07YAZ-S3AA100

1. Erase the DTC memory.
2. Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and then goes off.

Does the SRS indicator stay on, and is DTC 44-1x indicated?

YES - Go to step 3.

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

3. Turn the ignition switch OFF. Disconnect the battery negative cable, and wait for 3 minutes.
4. Check the connection between the SRS floor harness 2P connector and the right side impact sensor.

Is the connection OK?

YES - Go to step 5.

NO - Poor contact between the SRS floor harness 2P connector and the right side impact sensor; replace the right side impact sensor and/or the SRS floor harness, as needed.

5. Disconnect both seat belt tensioner 2P connectors.




6. Disconnect the right side impact sensor 2P connector (A).
7. Disconnect SRS unit connector B (28P) from the SRS unit.




8. Check resistance between the No. 25 and No. 26 terminals of SRS unit connector B (28P). Then check resistance between the No. 25 terminal and body ground and the No. 26 terminal and body ground. There should be an open circuit or at least 1 MOhms.

Is the resistance as specified?

YES - Go to step 9.

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

9. Reconnect the battery negative cable.
10. Turn the ignition switch ON (II).




11. Check for voltage between the No. 25 terminal of SRS unit connector B (28P) and body ground, and the No. 26 terminal and body ground. There should be 1 V or less.

Is the voltage as specified?

YES -Go to step 12.

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

12. Turn the ignition switch OFF.




13. Connect the SRS inflator simulator jumper connector) and the simulator lead H to the SRS floor harness 2P connector (A).




14. Check resistance between the No. 25 and No. 26 terminals of SRS unit connector B (28P). There should be 1 Ohm or less.

Is the resistance as specified?

YES - Faulty right side impact sensor. Replace the right side impact sensor.

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