• 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.

• Vehicle was driven in the city area (or on free-
way) for 10 minutes or more.
(b) Monitor Conditions
(1) Turn the ignition switch off and wait for 6 hours.
HINT:
Do not start the engine until checking Readiness
Monitor status. If the engine is started, the step
described above must be repeated.
(c) Monitor Status
(1) Connect an intelligent tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Turn the tester or scan tool ON.
(4) Check the Readiness Monitor status displayed
on the tester or scan tool.
If the status does not switch to COMPL
(complete), restart the engine, make sure that
the preconditions have been met, and then
perform the Monitor Conditions again.
4. A/F SENSOR AND HO2S MONITORS
(a) Preconditions
The monitor will not run unless:
• 2 minutes or more have elapsed since the engine
was started.
• The Engine Coolant Temperature (ECT) is 75
C
(167
F) or more.
• Cumulative driving time at a vehicle speed of 30
mph (48 km/h) or more exceeds 6 minutes.
• Air-fuel ratio feedback control is performed.
• Fuel-cut control is performed for 8 seconds or
more (for the Rear HO2 Sensor Monitor).
(b) Drive Pattern for front A/F sensor and HO2 sensor.
(1) Connect an intelligent tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Turn the tester ON.
(4) Clear the DTCs.
(5) Start the engine, and warm it up until the ECT
reaches 75
C (167F) or higher.
(6) Drive the vehicle at 38 mph (60 km/h) or more
for at least 10 minutes.
(7) Change the transmission to the 2nd gear.
(8) Accelerate the vehicle to 40 mph (64 km/h) or
more by depressing the accelerator pedal for at
least 10 seconds (Procedure "A").
(9) Soon after performing procedure "A" above,
release the accelerator pedal for at least 4
seconds without depressing the brake pedal, in
order to execute fuel-cut control (Procedure "B").
(10) Allow the vehicle to decelerate until the vehicle
speed declines to less than 6 mph (10 km/h)
(Procedure "C").
(11) Repeat procedures from "A" through "C" above
at least 3 times in one driving cycle.
