2.CHECK WHEEL SENSOR OUTPUT SIGNAL
1. Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.
2. Turn on the ABS active wheel sensor tester power switch.
NOTE:
The green POWER indicator should illuminate. If the POWER indicator does not illuminate, replace the
battery in the ABS active wheel sensor tester before proceeding.
3. Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel
sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal.
NOTE:
If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and
retest.
Does the ABS active wheel sensor tester detect a signal?
YES >> GO TO 3
NO >> Replace the wheel sensor. Refer to BRC-182, "
Removal and Installation".
3.CHECK TIRES
Check for inflation pressure, wear and size of each tire.
Are tire pressure and size correct and is tire wear within specifications?
YES >> GO TO 4
NO >> Adjust tire pressure or replace tire(s).
4.CHECK WHEEL BEARINGS
Check wheel bearing axial end play. Refer to FAX-5, "
On-Vehicle Inspection and Service" (front) or RAX-5,
"On-Vehicle Inspection and Service" (rear).
Is the inspection result normal?
YES >> GO TO 5
NO >> Repair or replace as necessary. Refer to FA X - 7 , "
Removal and Installation" (front) or RAX-6,
"Removal and Installation" (rear).
5.CHECK WIRING HARNESS FOR SHORT CIRCUIT
1. Disconnect ABS actuator and electric unit (control unit) connec-
tor and wheel sensor connector of malfunction code No.
2. Check continuity between wheel sensor harness connector ter-
minals and ground.
Is the inspection result normal?
YES >> GO TO 6
NO >> Repair the circuit.
6.CHECK WIRING HARNESS FOR OPEN CIRCUIT
1. Check continuity between ABS actuator and electric unit (control unit) harness connector E125 and the
malfunctioning wheel sensor harness connector E18, E117, C10, or C11. Continuity should not exist.

CAUTION:
 Sudden turns (such as spin turns, acceleration turns), drifting, etc. when VDC function is OFF may
cause the yaw rate/side/decel G sensor system to indicate a malfunction. This is not a malfunction if
normal operation can be resumed after restarting the engine.
 If vehicle is on turn table at entrance to parking garage, or on other moving surface, VDC OFF indica-
tor lamp may illuminate and CONSULT-III self-diagnosis may indicate yaw rate sensor system mal-
function. However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of
turn table or other moving surface, and start engine. Results will return to normal.
INSPECTION PROCEDURE
1.CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector E125 and yaw rate/side/decel G sensor

C1156 ST ANG SEN COM CIR
DescriptionINFOID:0000000001731152
The steering angle sensor is connected to the ABS actuator and electric unit (control unit) in addition to CAN
lines. CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle
multiplex communication line with high data communication speed and excellent error detection ability. Many
electronic control units are equipped onto a vehicle, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.
