Toyota Corolla (E120): 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 speed sensor induces an ac voltage.
Since the frequency of this ac voltage changes in direct proportion to the speed of the rotor, the frequency is used by the ecu to detect the speed of each wheel.
Hint
: Dtc no. C0200/31 and c1235/35 is the right front speed sensor.
Dtc no. C0205/32 and c1236/36 is the left front speed sensor.

Circuit description
The side squib (rh) circuit consists of the airbag sensor assy center and
front seat airbag assy (rh).
It causes the srs to deploy when the srs deployment conditions are satisfied.
Dtc b0110/43 is recorded when a short is detected in the side squib (rh)
circuit.

Correct use of the seat
belts
Extend the shoulder belt so
that it comes fully over the
shoulder, but does not come
into contact with the neck or
slide off the shoulder.
Position the lap belt as low as
possible over the hips.
Adjust the position of the
seatback. Sit up straight and
well back in the seat.
Do not twist ...
