Toyota Corolla Repair Manual: Inspection procedure

1 Check side squib(lh) circuit(airbag sensor assy center front seat airbag 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 front seat airbag assy (lh).
  3.  for the connector (on the front seat airbag assy side) between the airbag sensor assy center and the front seat airbag assy (lh), measure the resistance between sfl+ and body ground.

    Ok: resistance: 1 mw or higher

2 Check air bag sensor assy center

2 Check air bag sensor assy center

Sst 0984318040

  1. Connect the connector to the airbag sensor assy center.
  2.  using a service wire, connect sfl+ and sfl of the connector (on the front seat airbag assy side) between the airbag sensor assy center and the front seat airbag assy (lh).
  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 at 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 b0117/45 is not output.

Hint

: codes other than code b0117/45 may be output at this time, but they are not relevant to this check.
