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)
NOTE:

- Before doing this troubleshooting procedure, review SRS Precautions and Procedures and General Troubleshooting Information.
- 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 and retest.

1. Clear the DTC memory.

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

1. Read the DTC.

Is DTC 44-1x indicated?

YES

-

- If DTC 44-11 is indicated, go to Step 4 .
- If DTC 44-1x except 44-11 is indicated alone or DTC 44-11 and 46-11 are indicated, faulty left side impact sensor (first); replace the left side impact sensor (first). ■

NO | - | Intermittent failure, the system is OK at this time. Go to Troubleshooting Intermittent Failures. If another DTC is indicated, troubleshoot the DTC.

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

1. Do the battery terminal disconnection procedure, then wait for 3 minutes.

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

1. Disconnect SRS unit connector B (39P) from the SRS unit.

1. Connect an SRS short canceller (070AZ-SAA0100) to the No. 38 and the No. 39 terminals of SRS unit connector A (39P).

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

Is the resistance as specified?

YES | - | Go to Step 10 .
NO | - | Short in the SRS floor wire harness; replace the SRS floor wire harness.■

1. Measure the resistance between No. 38 terminal of SRS unit connector B (39P) and body ground, and between the No. 39 terminal and body ground. There should be an open circuit at least 1 MΩ.

Is the resistance as specified?

YES | - | Go to Step 11 .
NO | - | Short to ground in the SRS floor wire harness; replace the SRS floor wire harness.■

1. Do the battery terminal reconnection procedure.

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

1. Measure the voltage between No. 38 terminal of SRS unit connector B (39P) and body ground, and between the No. 39 terminal and body ground. There should be less than 1.0 V.

Is the voltage as specified?

YES | - | Go to Step 14 .
NO | - | Short to power in the SRS floor wire harness; replace the SRS floor wire harness.■

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

1. Measure the resistance between the No. 2 terminal of the SRS floor wire harness 4P connector and the No. 39 terminal of the SRS unit connector B (39P), and between the No. 3 terminal of the SRS floor wire harness 4P connector and the No. 38 terminal of the SRS unit connector B (39P). There should be 0−1.0 Ω.

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 SRS floor wire harness; replace the SRS floor wire harness.■
