Toyota Corolla Repair Manual: Inspection procedure

1 Check d squib circuit(airbag sensor assy center horn button 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 horn button 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 spiral cable subassy .
  4. for the connector (on the spiral cable subassy side) between the horn button assy and the spiral cable subassy, measure the resistance between d+ and d.

    Ok: resistance: 1 mw or higher

2 Check air bag sensor assy center

2 Check air bag sensor assy center

Sst 0984318040

  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 b0100/13 is not output.

Hint

: codes other than code b0100/13 may be output at this time, but they are not relevant to this check.

4 Check instrument panel wire(airbag sensor assy center spiral cable subassy)

  1. Disconnect the connector of the instrument panel wire.
  2.  release the airbag activation prevention mechanism of the connector (on the airbag sensor assy center side) between the airbag sensor assy center and the spiral cable subassy .
  3.  for the connector (on the spiral cable subassy side) between the airbag sensor assy center and the spiral cable subassy, measure the resistance between d+ and d.

    Ok: resistance: 1 mΩ or higher

5 Check spiral cable subassy

5 Check spiral cable subassy

  1. Release the airbag activation prevention mechanism of the spiral cable subassy connector on the airbag sensor assy center side .
  2.  for the orange connector (on the spiral cable subassy side) between the horn button assy and the spiral cable subassy, measure the resistance between d+ and d.

    Ok: resistance: 1 mΩ or higher
