Toyota Corolla Repair Manual: 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 connector 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.
  5.  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 voltage between p2+ and body ground.

Ok: voltage: below 1 v
