(3) Clear the DTCs stored in ECU by depressing the
brake pedal 8 or more times within 5 sec.
(4) Check that the ABS warning light indicates the nor-
mal code blinking pattern.
(5) Remove the SST from the DLC3.
SST 09843±18040
HINT:
Disconnecting the battery cable during repairs will not erase the
DTCs in the ECU.
(f) With using hand±held tester:
Clear the DTCs.
(1) Turn the ignition switch ON.
(2) Operate the hand±held tester to erase the codes.
HINT:
Please refer to the hand±held tester operator's manual for fur-
ther details.
2. DATA LIST
HINT:
According to the DATA LIST displayed on the Hand±held tester, you can read the value and status of the
switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of trouble-
shooting is one of the methods to shorten the labor time.
(a) Connect the Hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) From the display on the tester, read the ºDATA LISTº.

4. FREEZE FRAME DATA
(a) The vehicle (sensor) status memorized during ABS operation or at the time of error code detection can
be displayed using the hand±held tester.
(b) Only one record of the freeze frame data is stored and the freeze frame data generated during ABS
operation are constantly updated. Also, the number of the operations of the ignition switch ºONº after
the freeze frame data is stored can be memorized up to 31 and it can be displayed.
HINT:
If the ignition switch ºONº operation exceeds 31 times, º31º appears on the display.
(c) If the diagnosis code malfunction occurs, the freeze frame data at the occurrence of the malfunction
is stored but the ABS actuation data is not stored.

DIAGNOSTIC TROUBLE CODE CHART
HINT:
Using SST 09843±18040, connect the terminal Tc and CG of the DLC3.
If malfunction is not found when inspecting parts, inspect the ECU and grou\
nd points for poor contact.
If a malfunction code is displayed during the DTC check, check the circuit\
listed for that code. For de-
tails of each code, refer to the ºSee pageº for respective ºDTC No.º\
in the DTC chart.
When 2 or more DTCs are detected, perform circuit inspection one by one unti\
l the problem is identi-
fied.

6. With using hand±held tester:
ABS SENSOR SIGNAL CHECK (TEST MODE)
NOTICE:
After replacing the steering angle sensor and/or ECU, perform zero point calibration of the steering
angle sensor or system decision (When replacing the ECU) (See step 7.).
HINT:
If the ignition switch is turned from ON to ACC or LOCK during test mode, the DTCs will be erased.
(a) Hook up the hand±held tester to the DLC3.
(b) Perform step 5. (c) to (d) on the previous page.
(c) Read the DTC by following the prompts on the tester screen.
HINT:
Please refer to the hand±held tester operator's manual for further details.
7. STEERING ANGLE SENSOR ZERO POINT CALIBRATION
NOTICE:
When replacing the steering angle sensor with column assembly or ECU, Engine and ECT ECU (A/T),
Engine ECU (M/T) or when adjusting the front wheel alignment or steering wheel center point in ac-
cordance with the removing or installing or replacing the suspension, axle or steering parts, make
sure to perform steering angle sensor zero point calibration.
(a) Using SST, connect terminals Ts and CG of the DLC3
.
SST 09843±18040
(b) Turn the ignition switch ON and keep the shift lever at P range.
(c) Make sure the steering off center angle is less than 3 when assembling the steering wheels (Smaller
value is desirable).
(d) Press the TRC OFF switch and hold it.
(e) Check that the following conditions are satisfied.
HINT:
Engine warning light comes on.
ABS warning light is blinking.
(f) Depress the brake pedal 3 times or more within 2 seconds.
