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.  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 p+ and body ground.

    Ok: resistance: 1 mΩ or higher

  1. Connect the connector to the airbag sensor assy center.
  2.  using a service wire, connect p+ and p– of the connector (on the instrument panel passenger airbag assy side) between the airbag sensor assy center and the instrument panel passenger airbag assy.
  3.  connect the negative (–) terminal cable to the battery, and wait at least for 2 seconds.
  4.  turn the ignition switch to on, and wait at least for 20 seconds.
  5.  clear the dtc stored in memory .
  6.  turn the ignition switch to lock, and wait at least for 20 seconds.
  7.  turn the ignition switch to on, and wait at least for 20 seconds.
  8.  check the dtc .

    Ok: dtc b0107/51 is not output.

Hint

: codes other than code b0107/51 may be output at this time, but they are not relevant to this check.
