INSPECTION PROCEDURE

HINT:

1 CHECK CURTAIN SHIELD AIRBAG ASSEMBLY LH (CURTAIN SHIELD SQUIB LH)

CHECK CURTAIN SHIELD AIRBAG ASSEMBLY LH (CURTAIN SHIELD SQUIB LH)

  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 curtain shield airbag assembly LH.
  4.  Connect the white wire side of SST (resistance 2.1 Ω) to the floor wire.

CAUTION: Never connect a tester to the curtain shield airbag assembly LH (curtain shield squib LH) 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.
  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 B1165/87 is not output.

HINT: Codes other than DTC B1165/87 may be output at this time, but they are not related to this check.

REPLACE CURTAIN SHIELD AIRBAG ASSEMBLY LH

2 CHECK CONNECTORS

  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 floor wire.
  4. Check that the floor wire connectors (on the curtain shield airbag assembly LH side) are not damaged.

OK: The lock button is not disengaged, and the claw of the lock is not deformed or damaged.

3 CHECK FLOOR WIRE (CURTAIN SHIELD SQUIB LH CIRCUIT)

CHECK FLOOR WIRE (CURTAIN SHIELD SQUIB LH CIRCUIT)

  1. Disconnect the connector from the center airbag sensor assembly.
  2. Release the activation prevention mechanism built into connector "B".
  3. Measure the resistance according to the value(s) in the table below.

Standard resistance

Standard resistance

4 CHECK CENTER AIRBAG SENSOR ASSEMBLY

CHECK CENTER AIRBAG SENSOR ASSEMBLY

  1. Connect the connectors to the curtain shield airbag assembly LH 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.  Turn the ignition switch to the LOCK position.
  6.  Turn the ignition switch to the ON position, and wait for at least 60 seconds.
