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.  connect the negative () terminal cable to the battery, and wait at least for 2 seconds.
  4.  turn the ignition switch to on.
  5.  for the orange connector (on the spiral cable subassy side) between the horn button assy and the spiral cable subassy, measure the voltage between d+ and body ground.

    Ok: voltage: below 1 v

2 Check air bag sensor assy center
