Inspection 1 Wheel Sensor System

EFS003GZ

INSPECTION PROCEDURE

DTC C1101, C1102, C1103, C1104, C1105, C1106, C1107, C1108 or C1115
First use CONSULT-II self-diagnosis results to determine positions of malfunctioning wheel sensors. Then
inspect parts and determine which parts to replace.

1. 

CONNECTOR INSPECTION

1.

Disconnect the ABS actuator and electric unit (control unit) connector E39 and wheel sensor of malfunc-
tion 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.

Disconnect connector from wheel sensor of malfunction code No.

2.

Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.

3.

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.

4.

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

>> GO TO 6.

3. 

CHECK TIRE

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, "Front Wheel Bearing"

  or 

RAX-6, "Rear Wheel Bearing"

 .

Is axial end play within specifications?

Yes

>> GO TO 5.

No

>> Repair as necessary. Refer to 

FAX-9, "WHEEL HUB AND KNUCKLE"

  or 

RAX-7, "WHEEL HUB"

 .

Then retest.

5. 

SENSOR ROTOR INSPECTION

Check for damage to sensor rotor teeth.

Is inspection result OK?

OK

>> GO TO 6.

NG

>> Replace sensor rotor. Refer to 

BRC-49, "Front Sensor Rotor"

  or 

BRC-49, "Rear Sensor Rotor

(4WD)"

 .

BRC-36

[ABS]

TROUBLE DIAGNOSIS

6. 

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 resistance between harness connector terminal and
ground.

OK or NG?

OK

>> GO TO 7.

NG

>> Repair the circuit.

7. 

CHECK WIRING HARNESS FOR OPEN CIRCUIT

1.

Disconnect ABS actuator and electric unit (control unit) connector and wheel sensor connector of mal-
function code No.

2.

Check continuity between both wiring harness ends.

OK or NG?

OK

>> Replace the ABS actuator and electric unit (control unit). Refer to 

BRC-51, "ABS Actuator and

Electric Unit"

 .

NG

>> Repair the circuit.

Inspection 2 ABS Actuator and Electric Unit (Control Unit) System

EFS003H0

DTC C1110

Inspection Procedure

1. 

CHECKING SELF-DIAGNOSIS RESULTS

Check self-diagnosis results.

Does anything other than “CONTROLLER FAILURE” appear on self-diagnosis display?

YES

>> Repair or replace the items indicated. Then perform self-diagnosis again.

NO

>> Replace ABS actuator and electric unit (control unit). Then perform ABS actuator and electric

unit (control unit) self-diagnosis again.

Continuity should not exist.
