INSPECTION PROCEDURE

HINT:

1 CHECK FRONT SEAT OUTER BELT ASSEMBLY RH (FRONT PRETENSIONER SQUIB RH)

CHECK FRONT SEAT OUTER BELT ASSEMBLY RH

  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 seat outer belt assembly RH.
  4.  Connect the white wire side of SST (resistance 2.1 Ω) to the floor wire No. 2.

CAUTION: Never connect a tester to the front seat outer belt assembly RH (front pretensioner squib RH) 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.
