Toyota Corolla (E120): Inspection procedure

1 Check p squib circuit(airbag sensor assy center – instrument panel passenger airbag assy)

  1. Disconnect the negative (–) terminal cable from the battery, and wait at least for 90 seconds.
  2.  disconnect the connectors between the airbag sensor assy center and the instrument panel passenger airbag assy.
  3.  release the airbag activation prevention mechanism of the connector (on the airbag sensor assy center side) between the airbag sensor assy center and the instrument panel passenger airbag assy .
  4.  for the connector (on the instrument panel passenger airbag assy side) between the airbag sensor assy center and the instrument panel passenger airbag assy, measure the resistance between p2+ and p2–.

    Ok: resistance: 1 mw or higher

  1. Connect the connector to the airbag sensor assy center.
  2.  connect the negative (–) terminal cable to the battery, and wait at least for 2 seconds.
  3.  turn the ignition switch to on, and wait at least for 20 seconds.
  4.  clear the dtc stored in memory .
  5. turn the ignition switch to lock, and wait at least for 20 seconds.
  6.  turn the ignition switch to on, and wait at least for 20 seconds.
  7.  check the dtc .

    Ok: dtc b1185/57 is not output.

Hint

: codes other than code b1185/57 may be output at this time, but they are not relevant to this check.

    Circuit description
    The camshaft position sensor (g22+ signal) consists of a magnet, iron core and pickup coil. The g22+ signal plate has 3 teeth on its outer circumference and is installed on the camshaft timing pulley. When the camshafts rotate, the protrusion on the signal plate and the air gap on the pi ...

    Adjusting the mirrors
    Make sure that you can see backward clearly by adjusting the inside and outside rear view mirrors properly. CAUTION Observe the following precautions. Failure to do so may result in death or serious injury. ●Do not adjust the position of the driver’s seat while driving. Doing so could ...
