(d) Using TOYOTA break −out− box and TOYOTA hand− held
tester, measure the ECU terminal values.
(1) Hook up the T OYOTA hand−held tester and TOYO-
TA break−out−box to the vehicle.
(2) Read the ECU input/output values by following the prompts on the tester screen.
HINT:
TOYOTA hand −held tester has a ”Snapshot ” function. This re-
cords the measured values and is effective in the diagnosis of
intermittent problems.
Please refer to the TOYOTA hand−held tester/TOYOTA break
out−box operators manual for further details.
2. SPEED SENSOR SIGNAL AND DECELERATION SEN-
SOR CHECK
(a) Check the speed sensor signal. (1) Conform that the center differential is free.
(2) Turn the ignition switch OFF.
(3) Using SST, connect terminals Ts and E
1 of the
DLC1.
SST 09843−18020
(4) Start the engine.
(5) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page DI−230).
(6) Drive vehicle straight forward.
HINT:
Drive vehicle faster than 45 km/h (28 mph) for several seconds.
(7) Stop the vehicle.
(8) Using SST, connect terminals Tc and E
1 of the
DLC1.
SST 09843−18020
(9) Read the number of blinks of the ABS warning light.
HINT:
See the list of DTC on page DI−190 .
If every sensor is normal, a normal code is output (A cycle of
0.25 sec. ON and 0.25 sec. OFF is repeated).
If 2 or more malfunction are indicated at the same time, the low-
est numbered code will be displayed 1st.

(10) After doing the check, disconnect terminals Ts and
E
1, Tc and E1 of the DLC1, and turn the ignition
switch OFF.
(b) Deceleration sensor detection point check. (1) Confirm that the center differential is free.
(2) Turn the ignition switch OFF.
(3) Using SST, connect terminals Ts and E
1 of the
DLC1.
SST 09843−18020
(4) Start the engine.
(5) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page DI−230).
(6) Jack up the rear side of the vehicle slowly.
HINT:
When measuring the height, measure at the center of the lower
body of the vehicle. (7) Check that the warning light blinks.
If the warning light turns on, inspect the deceleration sensor
installation. If the sensor installation is OK, replace the decel-
eration sensor. (8) Jack down the vehicle slowly.
