C0200 / 31 - C1331 / 36Speed Sensor Circuit
DTC
C1332 / 38, C1333 / 39Speed Sensor Circuit
CIRCUIT DESCRIPTION
The speed sensor detects a wheel speed and sends the ap-
propriate signals to the ECU. These signals are used to control
of the ABS and VSC system. Each of the front and rear rotors
has 48 serrations.
When the rotors rotate, a magnetic field emitted by a permanent
magnet in the speed sensor generates 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 de-
tect the speed of each wheel.

When any of the following 1. to 3. is detected :
1. Vehicle speed is more than 40 km/h (25 mph), pulses
are not input for 0.01 sec.
2. After the initial start or restart and when the vehicle
speed has reached 12 km/h (7 mph), the wheel speed of
0 km/h (0 mph) is detected.
3. After the initial start or restart and when the vehicle
speed has reached 18 km/h (11 mph), the front wheel
speed of 0 km/h (0 mph) is detected.

INSPECTION PROCEDURE
HINT:
Start the inspection from step 1 in case of using the TOYOTA hand-held tester and start from step 2 in case
of not using the TOYOTA hand-held tester.
1 Check output value of the steering angle sensor.
PREPARATION:
(a) Connect the TOYOTA hand-held tester to the DLC3.
(b) Turn the ignition switch ON and push the TOYOTA hand-held tester main switch ON.
(c) Select the DATALIST mode on the TOYOTA hand-held tester.
CHECK:
Check that the steering wheel turning angle value of the steering angle sensor displayed on the TOYOTA
hand-held tester is appropriate when turning the steering wheel.
OK:
Steering wheel turning angle value must be appropriate.
OK Go to step 4.
NG
2 Check the installation condition of steering angle sensor and adapter.
NG Repair or replace steering angle sensor (See
page SR-12).
OK
3 Check for open and short circuit in harness and connector between steering
angle sensor, translate ECU and ABS & BA & TRAC & VSC ECU (See page
IN-30).
NG Repair or replace harness or connector.
OK

CIRCUIT DESCRIPTION
DTC No.DTC Detecting ConditionTrouble Area
C1237 / 37
Detection of any of conditions from 1. through 4.:
1. When the ignition switch is ON, the speed difference
between the rear right and rear left wheels is 5 km/h
(3mph) or more (vehicle speed: 100 km/h (62 mph) or
less).
2. When the ignition switch is ON, the slip difference be-
tween the reference wheel and any other wheels is 6 %
or more (vehicle speed: 100 km/h (62 mph) or more).
3. Continuous ABS control for 60 sec. or more.
4. Interference on 1 or more wheels for 20 sec. with the
brake pedal depressed, or for 5 sec. when the brake
pedal is not depressed.
Tire size
Speed sensor rotor
INSPECTION PROCEDURE
1 Check tire size.
NG Replace tires so that all 4 tires are the same in
size.
OK
2 Check sensor rotor (See page DI-267).
NG Replace speed sensor rotor.
OK
3 Check speed sensor (See page DI-267).
NG Replace speed sensor.
