INSPECTION PROCEDURE

HINT:

1 CHECK FRONT PASSENGER AIRBAG ASSEMBLY (FRONT PASSENGER SIDE SQUIB)

CHECK FRONT PASSENGER AIRBAG ASSEMBLY (FRONT PASSENGER SIDE SQUIB)

  1. Turn the ignition switch to the LOCK position.
  2.  Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.
  3.  Disconnect the connectors from the front passenger airbag assembly.
  4.  Connect the black wire side of SST (resistance 2.1 Ω) to the instrument panel wire.

CAUTION: Never connect a tester to the front passenger airbag assembly (front passenger side squib) for measurement, as this may lead to a serious injury due to airbag deployment.

NOTICE: Do not forcibly insert the SST into the terminals of the connector when connecting.

Insert the SST straight into the terminals of the connector.

SST 09843-18060

  1.  Connect the negative (-) terminal cable to the battery, and wait for at least 2 seconds.
  2.  Turn the ignition switch to the ON position, and wait for at least 60 seconds.
  3.  Clear the DTCs stored in memory (5).
  4.  Turn the ignition switch to the LOCK position.
  5.  Turn the ignition switch to the ON position, and wait for at least 60 seconds.
  6.  Check the DTCs

OK: DTC B0106/54 is not output. HINT: Codes other than DTC B0106/54 may be output at this time, but they are not related to this check.

Go to step 2

 REPLACE FRONT PASSENGER AIRBAG ASSEMBLY

2 CHECK INSTRUMENT PANEL WIRE (FRONT PASSENGER SIDE SQUIB CIRCUIT)

CHECK INSTRUMENT PANEL WIRE (FRONT PASSENGER SIDE SQUIB CIRCUIT)

  1. Turn the ignition switch to the LOCK position.
  2.  Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.
  3.  Disconnect the SST (resistance 2.1 Ω) from the instrument panel wire.
  4.  Disconnect the connector from the center airbag sensor assembly.
  5.  Measure the resistance according to the value(s) in the table below.

REPAIR OR REPLACE INSTRUMENT PANEL WIRE

3 CHECK CENTER AIRBAG SENSOR ASSEMBLY

CHECK CENTER AIRBAG SENSOR ASSEMBLY

  1. Connect the connectors to the front passenger airbag assembly and the center airbag sensor assembly.
  2.  Connect the negative (-) terminal cable to the battery, and wait for at least 2 seconds.
  3.  Turn the ignition switch to the ON position, and wait for at least 60 seconds.
  4.  Clear the DTCs stored in memory (5).
  5.  Turn the ignition switch to the LOCK position.
  6.  Turn the ignition switch to the ON position, and wait for at least 60 seconds.
  7.  Check the DTCs (5).

OK: DTC B0106/54 is not output. HINT: Codes other than code B0106/54 may be output at this time, but they are not related to this check.
