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.  for the orange connector (on the spiral cable sub–assy side) between the horn button assy and the spiral cable sub–assy, measure the resistance between d+ and body ground.

    Ok: resistance: 1 mw or higher

2 Check air bag sensor assy center

2 Check air bag sensor assy center

Sst 09843–18040

  1. Connect the connector to the airbag sensor assy center.
  2.  using a service wire, connect d+ and d– of the orange connector (on the spiral cable sub–assy side) between the horn button assy and the spiral cable sub–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 t 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 b0102/11 is not output.

Hint

: codes other than code b0102/11 may be output at this time, but they are not relevant to this check.
