DTC 44-12

DTC 44-12: Short to Ground or Short to Power/Open in Right Side Impact Sensor (first)

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 44-11 or 44-12 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 DTC Troubleshooting Index.

3. Turn the ignition switch OFF. Disconnect the battery negative cable, and wait for 3 minutes.
4. Check the connection between the right 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 the DTC 44-11 or 44-12 is still present, go to step 5.

5. Disconnect both seat belt tensioner 4P connectors.




6. Disconnect the right floor wire harness 2P connector (A) from the right side impact sensor (first).
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). There should be an open circuit or at least 1 M Ohms.

Is the resistance as specified?

YES - Go to step 9.

NO - Short in the left floor wire harness or right floor wire harness; replace the faulty harness.




9. Check 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 M Ohm.

Is the resistance as specified?

YES - Go to step 10.

NO - Short to ground in the left floor wire harness or right floor wire harness; replace the faulty harness.

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




12. Check 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 13.

NO - Short to power in the left floor wire harness or right floor wire harness; replace the faulty harness.

13. Turn the ignition switch OFF.




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




15. Check 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 - Go to step 16.




16. Disconnect the left floor wire harness 2P connector C684 (A) from the right floor wire harness connector C684 (B).




17. Check resistance between the No. 1 and No. 2 terminals of right floor wire harness 2P connector C684. There should be 1.0 Ohm or less.

Is the resistance as specified?

YES - Open in the left floor wire harness; replace the left floor wire harness.

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