Toyota Corolla (E120): Inspection procedure

1 Check wire harness(airbag sensor assy center – front seat inner 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 front seat inner belt assy (lh).
  3.  for the connector (on the airbag sensor assy center side) between the airbag sensor assy center and the front seat inner belt assy (lh), measure the resistance between lbe+ and body ground.

    Ok: resistance: 1 mw or higher

2 Check wire harness(airbag sensor assy center – front seat inner

2 Check wire harness(airbag sensor assy center – front seat inner belt assy lh)

  1. Connect the negative (–) terminal cable to the battery, and wait at least for 2 seconds.
  2.  turn the ignition switch to on.
  3.  for the connector (on the airbag sensor assy center side) between the airbag sensor assy center and the front seat inner belt assy (lh), measure the voltage between lbe+ and body ground.

    Ok: voltage: below 1 v

3 Check front seat inner belt assy lh

3 Check front seat inner belt assy 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.  connect the connector of the front seat inner belt assy (lh).
  4.  unlock the seat belt for the front driver’s seat.
  5.  for the connector (on the airbag sensor assy center side), measure the resistance between lbe+ and body ground.

    Ok: resistance: 1.0 Kw – 1.6 KΩ

4 Check front seat inner belt assy lh

4 Check front seat inner belt assy lh

  1. Lock the seat belt for the front driver’s seat.
  2.  for the connector (on the airbag sensor assy center side), measure the resistance between lbe+ and body ground.

    Ok: resistance: 100 w – 500 Ω

5 Check air bag sensor assy center

5 Check air bag sensor assy center

Sst 09843–18040

  1. Connect the connector to the airbag sensor assy center.
  2.  connect the negative (–) terminal cable to the battery, and wait at least for 2 seconds.
  3.  turn the ignition switch to on, and wait at least for 20 seconds.
  4.  clear the dtc stored in memory .
  5.  turn the ignition switch to lock, and wait at least for 20 seconds.
  6.  turn the ignition switch to on, and wait at least for 20 seconds.
  7.  check the dtc .

    Ok: dtc b0126/b0127/27 is not output.

Hint

: codes other than code b0126/b0127/27 may be output at this time, but they are not relevant to this check.

    Calibrating the compass
    The direction display deviates from the true direction determined by the earth’s magnetic field. The amount of deviation varies according to the geographic position of the vehicle. If you cross over a map boundary shown in illustration, the compass will deviate. To obtain higher precision or ...
