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

    Ok: dtc b1140/32 is not output.

Hint

: codes other than code b1140/32 may be output at this time, but they are not relevant to this check.

2 Check airbag sensor assy center connector

2 Check airbag sensor assy center connector

  1. Turn the ignition switch to lock.
  2.  disconnect the negative () terminal cable from the battery, and wait at least for 90 seconds.
  3.  check that the connectors is properly connected to the airbag sensor assy center.

3 Check side airbag sensor assy connector

3 Check side airbag sensor assy connector
