DTC 44-11:
No Signal From the Right Side Impact Sensor (first)
NOTE:
  1. Turn the ignition switch to ON (II), then wait for 10 seconds.
Is DTC 44-11 indicated?
YES -
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. Disconnect the negative cable from the battery, then wait at least 3 minutes.
  1. Check the connections between SRS unit connector B (39P) and the SRS unit, between the floor wire harness 2P or 4P connector and the left side impact sensor (first), and at floor wire harness 2P or 4P connector.
    • 2P: With side airbag/without side curtain airbag
    • 4P: With side airbag and side curtain airbag
Are the connections OK?
YES -
Go to Step 7 .
NO -
Repair the poor connections and retest.■
    • 2P: With side airbag/without side curtain airbag
    • 4P: With side airbag and side curtain airbag
  1. Measure the resistance between 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 floor wire harness; replace the 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 or at least 1 MΩ.
Is the resistance as specified?
YES -
Go to Step 11 .
NO -
Short to ground in the floor wire harness; replace the floor wire harness.■
  1. Reconnect the negative cable to the battery.
  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 floor wire harness; replace the floor wire harness.■
  1. Turn the ignition switch to LOCK (0).

  1. Measure the resistance between the following terminals of the floor wire harness 2P or 4P connector, and the SRS unit connector B (39P). There should be less than 1.0 Ω.
    • With side airbag/without side curtain airbag
    2P:
    39P:
    No. 2
    No. 38
    No. 1
    No. 39

    • With side airbag and side curtain airbag
    4P:
    39P:
    No. 3
    No. 38
    No. 2
    No. 39

Is the resistance as specified?
YES -
Go to Step 16 .
NO -
Open in the floor wire harness; replace the floor wire harness.■
  1. Substitute a known-good right side impact sensor (first) and recheck.
  1. Turn the ignition switch to ON (II), then wait for 10 seconds.
Is DTC 44-11 indicated?
YES -
NO -
Faulty right side impact sensor (first); replace the right side impact sensor (first).
