5.SPEED SENSOR SIGNAL CHECK
HINT:
If the ignition switch is turned from ON to ACC or LOCK during
the test mode, the DTCs of the sensor check function will be
erased.
(a)Check the sensor signal.(1)Start the engine.
(2)Connect the hand±held tester to the DLC3.
(3)Select the TEST MODE.
(4)Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page 05±737). (5) Drive the vehicle straight forward.
HINT:

Drive the vehicle faster than 45 km/h (28 mph) for several
sec.

There is a case that the sensor check is not completed if
the vehicle has its wheels spun or its steering wheel
steered during this check.
(6) Stop the vehicle.
(7) Using SST, connect the terminals Tc and CG of the DLC3.
(b) Read the DTC from the hand±held tester screen.
HINT:

See the list of DTCs shown on the 05±704.

Please refer to the hand±held tester operator's manual
for further details.

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.

PRE±CHECK
1.DIAGNOSIS SYSTEM
(a)Check the warning lights. (1)Release the parking brake lever.
(2)When the ignition switch is turned ON, check thatthe ABS warning light, Brake warning light, VSC
warning light, TRC OFF indicator light and SLIP in-
dicator light come on for approx. 3 seconds.
HINT:

When the parking brake is applied or brake fluid level is
low, the Brake warning light comes on.

If the ECU stores DTC, the ABS warning light , VSC warn-
ing light and TRC OFF indicator light come on.

If the indicator check result is not normal, proceed to trou-
bleshooting for the light circuit.

TRC OFF indicator light circuit05±844
SLIP indicator light circuit05±848
(b) Without using hand±held tester: Check the DTC.
(1) Using SST, connect terminal Tc and CG of theDLC3.
SST 09843±18040
(2) Turn the ignition switch ON.
(3) Read the DTC from the ABS warning light or VSC warning light on the combination meter.
HINT:

If no code appears, inspect the diagnostic circuit, ABS
warning light circuit or VSC warning light circuit.

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.
Trouble areaSee Page
Ts terminal circuit05− 854
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).
