Toyota Corolla Repair Manual: Inspection procedure

1 Check front airbag sensor (lh) circuit (to b+)(airbag sensor assy center airbag sensor front 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 airbag sensor front 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 airbag sensor assy center side) between the airbag sensor front lh and the airbag sensor assy center, measure the voltage between body ground and each of +sl and sl.

    Ok: voltage: below 1 v

2 Check front airbag sensor(lh) circuit(to ground)(airbag sensor

2 Check front airbag sensor(lh) circuit(to ground)(airbag sensor assy center airbag sensor front lh)

  1. Turn the ignition switch to lock.
  2.  disconnect the negative () terminal cable from the battery, and wait at least for 90 seconds.
  3.  for the connector (on the airbag sensor assy center side) between the airbag sensor front lh and the airbag sensor assy center, measure the resistance between body ground and each of +sl and sl.

    Ok: resistance: 1 mΩ or higher

3 Check front airbag sensor (lh) circuit(open)(airbag sensor assy

3 Check front airbag sensor (lh) circuit(open)(airbag sensor assy center airbag sensor front lh)

5 Check air bag sensor assy center

Sst 0984318040

  1. Disconnect the negative () terminal cable from the battery, and wait at least for 90 seconds.
  2.  connect the airbag sensor front lh connector and airbag sensor assy center connector.
  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 b1158/b1159/16 is not output.

Hint

: codes other than code b1158/b1159/16 may be output at this time, but they are not relevant to this check.

6 Check engine room main wire harness (to b+)(conector airbag sensor front lh)

  1. Turn the ignition switch to lock.
  2.  disconnect the negative () terminal cable from the battery, and wait at least for 90 seconds.
  3.  disconnect the connector between the engine room main wire and the instrument panel wire.
  4.  connect the negative () terminal to the battery, and wait at least for 2 seconds.
  5.  turn the ignition switch to on.
  6.  for the engine room main wire connector (on the airbag sensor assy center side) between the airbag sensor assy center and the airbag sensor front lh, measure the voltage between body ground and each of +sl and sl.

    Ok: voltage: below 1 v
