Toyota Corolla Repair Manual: Inspection procedure

1 Check side squib(lh) circuit(airbag sensor assy center front seat airbag 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 airbag assy (lh).
  3.  for the connector (on the front seat airbag assy side) between the airbag sensor assy center and the front seat airbag assy (lh), measure the resistance between sfl+ and sfl.

    Ok: resistance: below 1 Ω

2 Check air bag sensor assy center

2 Check air bag sensor assy center

Sst 0984318040

  1. Connect the connector to the airbag sensor assy center.
  2.  using a service wire, connect sfl+ and sfl of the connector (on the front seat airbag assy side) between the airbag sensor assy center and the front seat airbag assy (lh).
  3.  connect the negative () terminal cable to the battery, and wait at least 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 b0116/48 is not output.

Hint

: codes other than code b0116/48 may be output at this time, but they are not relevant to this check.

Circuit description
The variable valve timing (vvt) system includes the ecm, the oil control valve (ocv) and the vvt controller. The ecm sends a target dutycycle control signal to the ocv. This control signal, applied to the ocv, regulates the oil pressure supplied to the vvt controller. Camshaft timing co ...

For vehicles equipped with srs airbag and seat belt pretensioner
Hint: the vehicle is equipped with an srs (supplemental restraint system), such as the horn button assembly, the instrument panel passenger airbag assembly, the front seat airbag assembly, the center airbag sensor assembly, the front airbag sensor, the side airbag sensor and the seat belt p ...

Circuit description
The vapor pressure sensor, vsv for canister closed valve (ccv), vsv for pressure switching valve are used to detect abnormalities in the evaporative emission control system. The ecm decides whether there is an abnormality in the evaporative emission control system based on the vapor pressur ...
