DTC 44-1x

DTC 44-1x ("x" can be 0 thru 9 or A thru F): No Signal from the Right Side Impact Sensor (first)

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

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 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. Troubleshooting Intermittent Failures If another DTC is indicated, troubleshoot the DTC.

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

Is the connection OK?

YES - Go to step 5.

NO - Repair the poor connection and retest. If DTC 44-1x is still present, go to step 5.

5. Disconnect the floor wire harness 2P connector (A) from the right side impact sensor (first).






6. Disconnect SRS unit connector B (28P) from the SRS unit.
7. Measure the 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 Mohm.






Is the resistance as specified?

YES - Go to step 8.

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

8. Measure the 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 Mohm.






Is the resistance as specified?

YES - Go to step 9.

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

9. Reconnect the negative cable to the battery.
10. Turn the ignition switch ON (II).
11. Measure the 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 step 12.

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

12. Turn the ignition switch OFF.
13. Connect the SRS inflator simulator (jumper connector) and simulator lead H to the floor wire harness 2P connector (A).






14. Measure the resistance between the No. 25 and No. 26 terminals of SRS unit connector B (28P). There should be 1.0 ohm or less.






Is the resistance as specified?

YES - Faulty right side impact sensor (first) or SRS unit; replace the right side impact sensor (first). If the problem is still present, replace the SRS unit.

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