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 connectors between the airbag sensor assy center and the instrument panel passenger airbag assy.
  3.  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 resistance between p2+ and p2–.

    Ok: resistance: below 1Ω

2 Check air bag sensor assy center

2 Check air bag sensor assy center

Sst 09843–18040

  1. Connect the connector to the airbag sensor assy center.
  2.  using a service wire, connect p2+ and p2– of the connector (on the instrument panel passenger airbag assy side) 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, 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 b1186/58 is not output.

Hint

: codes other than code b1186/58 may be output at this time, but they are not relevant to this check.
