5. Without using hand −held tester:
ABS SENSOR SIGNAL CHECK (TEST MODE)
NOTICE:
After replacing the steering angle sensor and/or ECU, per-
form 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) Procedures for test mode:
(1) Turn the ignition switch OFF.
(2) Using SST, connect terminal Ts and CG of the DLC3.
SST 09843 −18040
(3) Check that the steering wheel is in the straight −
ahead position and shift the shift lever to P range.
(4) Turn the ignition switch ON.
(5) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit or Ts terminal circuit.

ABS warning light circuit05−827
(b) Check the speed sensor signal.
(1) Drive the vehicle straight forward at the speed of 45
km/h (28 mph) or over for several seconds and
check that the ABS warning light goes off.
HINT:
The sensor check may not be completed if the wheels spin or
the steering wheels are steered during this check.
(c) Stop the vehicle.
(d) Using SST, connect terminal Tc and CG of the DLC3. SST 09843 −18040
(e) Read the number of blinks of the ABS warning light.
HINT:
S See the list of DTCs on page 05− 766.
SIf every sensor is normal, the normal code is output (A
cycle of 0.25 second ON and 0.25 second OFF is re-
peated).

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.
