INSPECTION PROCEDURE
1 Check ABS & TRAC actuator solenoid.
PREPARATION:
Disconnect the 2 connectors from ABS & TRAC actuator.
CHECK:
Check continuity between terminals A8 ± 4 and A7 ± 1, 2, 3, 4,
5, 6, 7, 8, 9, 10, 11, 12 of ABS & TRAC actuator connector.
OK:
Continuity
HINT:
Resistance of each solenoid coil is 1.2 W.
NG Replace ABS & TRAC actuator.
OK

DTC31, 32, 33, 34Speed Sensor Circuit
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the ap-
propriate signals to the ECU. These signals are used to control
the ABS and TRAC system. The front and rear rotors each have
48 serrations.
When the rotors rotate, the magnetic field emitted by the perma-
nent magnet in the speed sensor generates an AC voltage.
Since the frequency of this AC voltage changes in direct propor-
tion to the speed of the rotor, the frequency is used by the ECU
to detect the speed of each wheel.

DTC No.DTC Detecting ConditionTrouble Area
31, 32, 33, 34
Detection of any of conditions from 1. through 3.:
1. ABS is in non±operation, wheel speed is 10 km/h or
more, one eighth of maximum wheel speed is greater
than the minimum wheel speed, one eighth of maximum
wheel speed is smaller than the rear maximum wheel
speed or momentary interruption of both the rear wheels
are shown in the 15 sec. or more continuously.
2. ABS is in non±operation, momentary interruption of
speed sensor occurs 7 times or more in the mean time
of switching the ignition switch ON and OFF or vehicle
speed is 20 km/h (12 mph) or more and the condition of
noise interference or non±noise interference occurs 75
times or more within 5 sec.
3. Vehicle is at a stop, malfunction signal of vehicle speed
sensor hardware open circuit is ON for 1.02 sec. contin-
uously since starting the checking of a certain vehicle.

HINT:

DTC No. 31 is for the right front speed sensor.

DTC No. 32 is for the left front speed sensor.

DTC No. 33 is for the right rear speed sensor.

DTC No. 34 is for the left rear speed sensor.
Fail safe function:
If any trouble occurs in the speed sensor circuit, the ECU cuts off current to the ABS & TRAC solenoid relay
and prohibits ABS control and TRAC control.
