4. INSPECT SENSOR SIGNAL LEVEL
Drive the vehicle straight ahead at about 4 ±6 km/h (2.5
± 3.7 mph), and check that the warning light turns on after
a 1 second pause.
If the warning light turns on without blinking when the ve-
hicle speed is not within the specified speed range above,
stop the vehicle and read the diagnostic code, and repair
the malfunctioning parts.
(See step S on page BR±79)
HINT: If the warning light turns on while the vehicle speed
is within specified speed range above, the check is com-
pleted. And when the vehicle speed exceeds 6 km/h
(3.7mph), the warning light will blink again. In this condi-
tion, speed sensors are OK.
NOTICE: While the warning light is off, do not give any
shocks to vehicle such as acceleration, deceleration, brak-
ing, shift change, steering or shocks from the road condi-
tion.
(4WD)
(a) Remove the rubber cap from the Ts connector lo-
cated in front of the actuator.
(b) Connect the terminals of Ts connector.
(c) Pull the parking brake lever up, and start the engine.
NOTICE: Do not depress the brake pedal.
(d) Check that the warning light blinks about 4 times ev-
ery 1 second as shown.

5. INSPECT SENSOR SIGNAL CHANGE
Drive the vehicle straight ahead at about 45 ± 55 krn/h
(28.0 ± 34.2 mph), and check that the warning light turns
on after a 1 second pause.
If the warning light turns on without blinking when the ve-
hicle speed is not within the specified speed range above,
stop the vehicle and read the diagnostic code, and repair
the malfunctioning .parts.
(See step 6 on this page)
HINT: If the warning light turns on while the vehicle speed
is within specified speed range above, the check is com-
pleted. And when the vehicle speed is not within specified
speed range, the warning light will blink again. In this con-
dition, sensor rotors are OK.
NOTICE: While the warning light is off, do not give any
shocks to vehicle such as acceleration, deceleration, brak-
ing, shift change, steering or shocks from the road condi-
tion.
HINT: The first number of blinks will equal the first digit
of a two digit diagnostic code. After a 1.5 second pause,
the 2nd number of blinks will equal the 2nd number of a
two digit code. If there are two or more codes, there will
be a 2.5 second pause between each code, and then
indication will begin again after a 4.0 second pause,
continuing in order from the smaller value up to the larg-
er one. 6. READ DIAGNOSTIC CODE
Stop the vehicle and disconnect the check connector, and
warning light will begin to blink. Read the number of
blinks.
(See DIAGNOSTIC CODE on page BR±81)
7. REPAIR MALFUNCTIONING PARTS
Repair or replace the malfunctioning parts.
HINT: When repairing or replacing parts, turn the ignition
switch OFF.

(c) Remove the short pin or wire from the Ts connector
and install the rubber cap to it.
(d) Turn the ignition switch off. 8. PERFORM FOLLOWING STEPS
(a) (2WD)
Turn the ignition switch on.
(4WD)

PRECAUTION
While checking the deceleration sensor diagnosis
system, A.B.S. does not work and brake system works as
normal brake system.
INSPECTION OF DIAGNOSIS SYSTEM
1. INSPECT BATTERY VOLTAGE
Inspect that the battery voltage is about 12 V.
2. CHECK THAT WARNING LIGHT TURNS ON
(a) Turn the ignition switch on.
(b) Check that the ºANTILOCKº warning light turns on for
3 seconds.
If not, inspect and repair or replace the fuse, bulb and wire
harness.
(e) Check that the ºANTILOCKº warning light turns off.
(d) Turn the ignition switch off.
3. PERFORM FOLLOWING STEPS
(a) Remove the rubber cap from the Ts connector lo-
cated in front of the actuator.
(b) Connect the terminals of Ts connector.
(c) Pull the parking brake lever up and depress the brake
pedal, and start the engine.
4. INSPECT SENSOR DETECTION POINT
(a) Jack up the rear side of the vehicle slowly as shown.
HINT: When measuring the height, measure at the center
of the rear bumper lower edge.
(b) Check that the warning light does not turn on.
(c) Jack down the vehicle and check that the warning
light blinking. (d) Check that the warning light blinks about 1 time every
1 second as shown.
If the warning light does not blink, inspect the parking brake
switch, stop light switch, Ts connector, deceleration sensor
installation and computer.
