(a) Work on a level surface. Use wheel chocks at all
times.
(b) Set the jack and rigid racks to the specified
locations of the vehicle accurately.
(c) When jacking up the vehicle, first release the
parking brake and move the shift lever to N.
(d) When jacking up the entire vehicle:
(1) When jacking up the front wheels first, make
sure wheel chocks are behind the rear wheels.
(2) When jacking up the rear wheels first, make sure
wheel chocks are in front of the front wheels.
(e) When jacking up only the front or rear wheels of the
vehicle:
(1) Before jacking up the front wheels, place wheel
chocks on both sides of the rear wheels.
(2) Before jacking up the rear wheels, place wheel
chocks on both sides of the front wheels.
(f) When lowering a vehicle that only has its front or
rear wheels jacked up:

• After the ABS warning light goes off and if
vehicle speed exceeds 50 mph (80 km/h), the
signal check code will be stored again.
Decelerate or stop the vehicle before the
speed reaches 50 mph (80 km/h).
• If the signal check has not been completed,
the ABS warning light blinks while driving
and the ABS system does not operate.
HINT:
When the signal check has been completed, the
ABS warning light goes off while driving and blinks
in the Test Mode pattern while stationary.
2. READ DTC
(a) Using SST, connect terminals TC and CG of the
DLC3.
SST 09843-18040
(b) Read the number of blinks of the ABS warning light.
HINT:
• See the list of DTC.
• If every sensor is normal, the normal system
code is output. (A cycle of 0.25 second ON and
0.25 second OFF is repeated.)
• If more than 1 malfunction is detected at the
same time, the lowest numbered code will be
displayed first.
(c) After performing the check, disconnect the SST
from terminals TS and CG, TC and CG of the DLC3
and turn the ignition switch off.

HINT:
The codes in this table are output only in Test Mode
(signal check).
4. SPEED SENSOR SIGNAL CHECK (WHEN USING
INTELLIGENT TESTER):
HINT:
• If the ignition switch is turned from the ON to the ACC
or LOCK position during Test Mode, DTCs of the
signal check function will be erased.
• During Test Mode, the ECU records all DTCs of the
signal check function. By performing the signal check,
the codes are erased if normality is confirmed. The
remaining codes are the codes where an abnormality
was found.
(a) Turn the ignition switch off.
(b) Check that the steering wheel is in the straight-
ahead position.
(c) Connect the intelligent tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Set the intelligent tester to Test Mode (select
"SIGNAL CHECK").
HINT:
Refer to the intelligent tester operator's manual for
further details.

(f) Check that the ABS warning light is blinking in the
Test Mode.
HINT:
If the ABS warning light does not blink, inspect the
TS and CG terminal circuit and the ABS warning
light circuit.
(g) Start the engine.
(h) Using the intelligent tester, perform the speed
sensor signal check in Test Mode.
(i) Drive the vehicle straight forward.
(j) Accelerate the vehicle to a speed of 28 mph (45 km/
h) or higher for several seconds and check that the
ABS warning light goes off.
HINT:
The signal check may not be completed if the
vehicle has its wheels spun.
(k) Stop the vehicle.
NOTICE:
• The speed sensor signal check may not be
completed if the steering wheel is turned or
the wheels are spun during the check.
• After the ABS warning light goes off and if
vehicle speed exceeds 50 mph (80 km/h), a
signal check code will be stored again.
Decelerate or stop the vehicle before the
speed reaches 50 mph (80 km/h).
• If the signal check has not been completed,
the ABS warning light blinks while driving
and the ABS system does not operate.
HINT:
When the signal check has been completed, the
ABS warning light goes off while driving and blinks
in the Test Mode pattern while stationary.
5. READ DTC
(a) Read the DTC(s) by following the tester screen.
HINT:
• Refer to the intelligent tester operator's manual
for further details.
• See the list of DTC.
