Toyota RAV4. Check curtain shield airbag assembly lh (driver side curtain shield squib)


  1. Turn the ignition switch off.
  2. Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
  3. Disconnect the connector from the curtain shield airbag lh.
  4. Connect the white wire side of sst (resistance 2.1 Ù) to connector c.

Caution:

Never connect a tester to the curtain shield airbag lh (driver side curtain shield squib) for measurement, as this may lead to a serious injury due to airbag deployment.

Notice:

Sst 09843-18060

Ok: dtc b1830, b1831, b1832, b1833 or 57 is not output.

Hint:

Dtcs other than dtc b1830, b1831, b1832, b1833 or 57 may be output at this time, but they are not related to this check.



  1. Check connector

  1. Turn the ignition switch off.
  2. Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
  3. Disconnect sst from connector c.
  4. Check that the floor wire connector (on the curtain shield lh side) is not damaged.

Ok: lock button is not disengaged, and claw of lock is not deformed or damaged.
