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).

    Hint

    : make sure that the connector is not damaged (the lock button is not disengaged, or the claw of the lock is not deformed or damaged). If the damage is found, replace the wire harness.

  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 seat belt pretensioner (lh) .
  4.  for the connector (on the seat belt pretensioner side) between the airbag sensor assy center and the seat belt pretensioner (lh), measure the resistance between pl+ and pl.

    Ok: resistance: 1 mw or higher

2 Check air bag sensor assy center
