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 and/or VSC 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
and/or VSC 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 deleted.

If 2 or more DTCs are detected at the same time, the low-
est numbered code is displayed first.
(f) After the check, disconnect the SST from terminal Ts and
CG, Tc and CG of DLC3 and turn the ignition switch to
OFF.

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.

Diagnostic steps permitting the use of the hand±held tester.
Fail safe function:
When a failure occurs in the ABS & BA & TRC & VSC systems, the ABS warning light, the VSC warning light
and the TRC OFF indicator light come on and the ABS & BA & TRC & VSC operations are prohibited. In
addition to this, when the failure that disables the EBD operation occurs, the brake warning light comes on
as well and the EBD operation is prohibited.

INSPECTION PROCEDURE
1 INSPECT DLC3 TERMINAL VOLTAGE(Ts TERMINAL)
(a) Turn the ignition switch ON.
(b) Measure the voltage between terminals Ts and CG of the
DLC3.
OK:
Voltage: 10 to 14 V
