SRS DTC Troubleshooting: 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 L 070AZ-SNAA300

NOTE:

- Before doing this troubleshooting procedure, review SRS Precautions and Procedures Service and Repair, General Troubleshooting Information Reading and Clearing Diagnostic Trouble Codes, and Battery Terminal Disconnection and Reconnection Procedures.
- Before replacing the SRS unit, check the SRS unit software version with the HDS. If the software version is not the latest, update the SRS unit software SRS Unit Update, and retest.

1. Clear the DTCs with the HDS Reading and Clearing Diagnostic Trouble Codes.

2. Turn the ignition switch to ON (II), then wait for 10 seconds.

3. Check for the DTCs with the HDS Reading and Clearing Diagnostic Trouble Codes.

6. Disconnect the floor wire harness 4P connector (A) from the right side impact sensor (first) Side Impact Sensor (First) Replacement.





7. Disconnect SRS unit connector B (39P) from the SRS unit Service and Repair.

8. Measure the resistance between SRS unit connector B (39P) terminals No. 38 and No. 39. There should be an open circuit or at least 1 MOhms.





Is the resistance as specified?

YES -

Go to step 9.

NO -

Short to another wire in the floor wire harness; replace the floor wire harness, then clear the DTC.�

9. Measure the resistance between body ground and SRS unit connector B (39P) terminals No. 38 and No. 39, individually. There should be an open circuit or more than 1 MOhms.





Is the resistance as specified?

YES -

Go to step 10.

NO -

Short to ground in the floor wire harness; replace the floor wire harness, then clear the DTC.�

10. Reconnect the negative cable to the battery.

11. Turn the ignition switch to ON (II).

12. Measure the voltage between body ground and SRS unit connector B (39P) terminals No. 38 and No. 39, individually. There should be less than 0.2 V.





Is the voltage as specified?

YES -

Go to step 13.

NO -

Short to power in the floor wire harness; replace the floor wire harness, then clear the DTC.�

13. Turn the ignition switch to LOCK (0).

14. Connect the SRS inflator simulator (jumper connector) and the black lead of simulator lead L (A) to the floor wire harness 4P connector (B).






15. Measure the resistance between SRS unit connector B (39P) terminals No. 38 and No. 39. There should be less than 1.0 Ohms.





Is the resistance as specified?

YES -

Faulty right side impact sensor(first) or SRS unit; replace the right side impact sensor (first) Side Impact Sensor (First) Replacement, then clear the DTC. If the problem is still present, replace the SRS unit SRS Unit Replacement.�

NO -

Open in the SRS floor wire harness; replace the floor wire harness, then clear the DTC.�
