DTC 31, 32, 33, 34, 35 Speed Sensor Circuit
CIRCUIT DESCRIPTION
The speed sensor detects the wheel speed and sends the ap-
propriate signals to the ECU. These signals are used to control
the ABS system. The front and rear rotors each have 48 serra-
tions.
When the rotor 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.

Detection of any of conditions 1 through 3:
1. At vehicle speed of 10 km/h (6 mph) or more, pulses are not
input for 5 sec.
2. Momentary interruption of the speed sensor signal occurs
at least 7 times in the time between switching the ignition
switch ON and switching it OFF
3. Abnormal fluctuation of speed sensor signals with the ve-
hicle speed 20 km/h (12 mph) or more

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 trouble occurs in the speed sensor circuit, the ECU cuts off current to the ABS control (solenoid) relay and
prohibits ABS control.

5. CENTER DIFFERENTIAL CLUTCH CONTROL (4WD)
THE CENTER DIFFERENTIAL CLUTCH CONTROL USES A LINEAR SOLENOID TYPE VALVE (SOLENOID VALVE SLD) TO CONTROL THE
CENTER DIFFERENTIAL CLUTCH. BY CONTROLLING THE FLUID PRESSURE, THE LIMITED SLIP DIFFERENTIAL EFFECT OF THE
CENTER DIFFERENTIAL CAN ALWAYS BE MAINTAINED AT THE OPTIMUM FOR THE CURRENT DRIVING CONDITIONS TO INCREASE
ROAD-HOLDING ABILITY.
SOLENOID VALVE SLD OPENS AND CLOSES IN RESPONSE TO SIGNALS FROM THE ENGINE CONTROL MODULE. THUS THE
SOLENOID MODULATOR VALVE MAINTAINS A CONSTANT FLUID PRESSURE FOR OPERATION OF THE CENTER DIFFERENTIAL
CLUTCH CONTROL VALVE AND CENTER DIFFERENTIAL CLUTCH.
*NORMAL DRIVING
SOLENOID VALVE SLD OPENS AND CLOSES IN RESPONSE TO THE THROTTLE OPENING ANGLE TO CONTROL THE FLUID
PRESSURE OPERATING ON THE CENTER DIFFERENTIAL CLUTCH. WHEN THE VEHICLE TAKES OFF IN FIRST GEAR WITH A
LARGE THROTTLE OPENING ANGLE, THE FLUID PRESSURE IS KEPT HIGH. SO EVEN IF THE VEHICLE TAKES OFF SUDDENLY OR
THE ROAD SURFACE IS SLIPPERY, SMOOTH, RELIABLE ACCELERATION IS POSSIBLE.
*SLIPPING
WHEN A LARGE DIFFERENCE OCCURS BETWEEN THE FRONT WHEEL SPEED AND REAR WHEEL SPEED AT LOW SPEEDS,
SOLENOID VALVE SLD IS FULLY CLOSED TO APPLY HIGH FLUID PRESSURE TO THE CENTER DIFFERENTIAL CLUTCH AND
PROVIDE A LARGE LIMITED SLIP DIFFERENTIAL EFFECT.
*WIDE CORNERING
WHEN DIFFERENCES ARISE BETWEEN THE FRONT WHEEL SPEED AND REAR WHEEL SPEED DUE TO DIFFERENCES IN THE
TURNING RADIUS DURING CORNERING AT LOW SPEEDS, SOLENOID VALVE SLD IS FULLY OPEN TO APPLY A WEAK LIMITED SLIP
DIFFERENTIAL EFFECT AND PERMIT SMOOTH CORNERING.
6. ELECTRONICALLY CONTROLLED TRANSMISSION PATTERN SELECT SW
IF THE ELECTRONICALLY CONTROLLED TRANSMISSION PATTERN SELECT SW IS CHANGED FROM NORMAL TO POWER, THE
CURRENT THROUGH THE POWER INDICATOR FLOWS TO GROUND, CURRENT FLOWS TO TERMINAL P OF THE ENGINE CONTROL
MODULE, THE ENGINE CONTROL MODULE OPERATES, AND SHIFT UP AND SHIFT DOWN OCCURS AT HIGHER VEHICLE SPEEDS
THAN WHEN THE SW IS IN NORMAL POSITION.

INSPECTION
1. INSPECT CENTER DIFFERENTIAL LOCK SYSTEM
(a) Inspect the differential lock operation.
(1) Use a lift or jack stand to lift up the vehicle so that
all 4 tires can rotate.
(2) Apply the parking brake and start the engine.
(3) Set the center differential lock switch to ON.
(4) Depress the clutch pedal and shift into the 2nd gear.
(5) With the engine idling, gradually engage the clutch
and check that the engine stops.
(6) With the parking brake and engine ON, turn the cen-
ter differential lock switch OFF.
(7) Depress the clutch pedal and shift into the 2nd gear.
(8) With the engine idling, gradually engage the clutch
and check that the front wheels rotate.
HINT:
This inspection must be done when the engine is idling.
(b) Inspect the center differential lock indicator operation.
(1) Turn the ignition switch ON.
(2) Check that when the differential lock switch is
turned ON and OFF, the differential lock indicator
lamp lights up and goes off, respectively.
(c) Inspect the center differential lock warning buzzer opera-
tion.
(1) Start the engine and check that the differential lock
warning buzzer does not sound when the center dif-
ferential lock switch is turned ON.
(2) Interchange the solenoid hose No.1 and solenoid
hose No.2 between the differential lock control sole-
noid No.1 and No.2 and the differential lock actua-
tor. And check that the differential lock warning
buzzer sounds when the differential lock switch is
turned OFF.
(3) Return the solenoid hose No.1 and solenoid hose
No.2 to their original location, and check that the dif-
ferential lock warning buzzer stops.
HINT:
Do the inspection with the vehicle stopped.
After finishing the inspection, inspect the differential lock
control solenoid hoses.

(i) Follow the above mentioned steps again. Between the
step (b) and (c), exchange 1 or 2 selected bolts.
HINT:
When exchanging the 2 bolts, exchange 1 bolt for each time.
6. ADJUST TOE−IN
(a) Remove the boot clamps.
(b) Loosen the tie rod end lock nuts.
(c) Turn the left and right rack ends an equal amount to adjust
the toe−in.

Try to adjust the toe−in to the center value.
Make sure that the length of the left and right rack ends
is the same.
