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.
