Note 1: If wheel sens or 2 for each wheel is indicated, check ABS actuator and electric unit (control unit) power supply voltage in addition
to wheel sensor circuit check.
Note 2: If multiple malfunctions are detected including CAN communication line [U1000], perform diagnosis for CAN communication line
first.
DATA MONITOR
Operation Procedure
1. After turning OFF the ignition switch, c onnect CONSULT-III to the data link connector.
2. Touch “ABS”, “DATA MONITOR” in order on the CONSULT-III screen. If “ABS” is not indicated, go to GI-36, "
CONSULT-III Data Link Connector (DLC) Circuit".
3. Return to the SELECT MONITOR ITEM screen, and touch “ECU INPUT SIGNALS”, “MAIN SIGNALS” or
“SELECTION FROM MENU”. Refer to the following information.
4. When “START” is touched, the data monitor screen is displayed.

INSPECTION PROCEDURE
1.CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector E33 and wheel sensor of malfunctioning
code.
Check the terminals for deformation, disconnection, looseness or damage.
OK or NG
OK >> GO TO 2.
NG >> Repair or replace as necessary.
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-34, "
Removal and Installation".
3.CHECK TIRES
Check for inflation pressure, wear and size of each tire. Refer to WT-28
.
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-6, "
On-Vehicle Inspection and Service" or RAX-6, "On-Vehi-
cle Inspection and Service".
OK or NG
OK >> GO TO 5.
NG >> Repair or replace as necessary. Refer to FA X - 6 , "
Removal and Installation" or RAX-6, "Removal
and Installation".
5.CHECK WIRING HARNESS FOR SHORT CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ABS actuator and elec tric unit (control unit) connec-
tor and wheel sensor connector of malfunction code No.
3. Check continuity between wheel sensor harness connector ter- minals and ground.
OK or NG
OK >> GO TO 6.
NG >> Repair the circuit.
6.CHECK WIRING HARNESS FOR OPEN CIRCUIT Continuity should not exist.

FRONT WHEEL SENSOR
Removal
CAUTION:
• As much as possible, avoid rotating wheel sensor when removing it
. Pull wheel sensors out without
pulling on sensor harness.
• Take care to avoid damaging wheel sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to wheel sensor wiring and loss of sensor
function.
1. Remove the front wheel and tire. Refer to WT-7, "
Adjustment".
2. Remove the front fender protector. Refer to EI-24, "
Removal and Installation".
3. Disconnect the front wheel sensor connector.
4. Remove the front wheel sensor.
Installation
Installation is in the reverse order of removal.
CAUTION:
• When installing, make sure there is no foreign material such as iron chips on and in the mounting
hole of the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove
any foreign material and clean the mount.
