Toyota Corolla Repair Manual: Inspection procedure

1 Check p/t squib(lh) circuit(airbag sensor assy center front seat outer belt assy lh)

  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 seat belt pretensioner (lh).
  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 seat belt pretensioner side) between the airbag sensor assy center and the seat belt pretensioner (lh), measure the voltage between pl+ and body ground.

    Ok: voltage: below 1v
