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.

Inspection procedure
1 Check relay (marking: starter cut)
Inspect the relay continuity, as shown in the illustration
and table.
Standard:
2 Check tvip ecu
Disconnect the tvip ecu connector.

Locking the doors from the outside without a key
1 Move the inside lock button to the lock position.
2 Close the door.
► Vehicles without a smart key system
The door cannot be locked if either of the front doors is open and the key is in
the engine switch.
► Vehicles with a smart key system
The door cannot be locked if the engin ...
Installation with LATCH system
1 Widen the gap between the seat cushion and seatback slightly.
► Type A
2 Latch the hooks of the lower straps onto the LATCH anchors. If the child restraint
has a top tether strap, the top tether strap should be latched onto the top tether
strap anchor.
