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 connector 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.
  5.  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 voltage between p2+ and body ground.

Ok: voltage: below 1 v

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

    Ok: dtc b1188/56 is not output.

Hint

: codes other than code b1188/56 may be output at this time, but they are not relevant to this check.

Circuit description
The speed sensor detects wheel speed and transmits the appropriate signals to the ecu. These signals are used for control of the abs control system. Each of the front and rear rotors has 48 serrations. When the rotors rotate, the magnetic field generated by the permanent magnet in the spe ...

Correct driving posture
1 Adjust the angle of the seatback so that you are sitting straight up and so that you do not have to lean forward to steer. 2 Adjust the seat so that you can depress the pedals fully and so that your arms bend slightly at the elbow when gripping the steering wheel. 3 Lock the head restraint ...

Circuit description
When a misfire occurs in the engine, hydrocarbons (hc) enter the exhaust in high concentrations. If this hc concentration is high enough, there could be an increase in exhaust emissions levels. High concentrations of hc passing through the catalyst also cause to temperature of the catalyst to ...
