TROUBLE DIAGNOSIS

Basic Inspection

EFS003I6

BASIC INSPECTION 1: BRAKE FLUID LEVEL AND LEAK INSPECTION

1.

Check fluid level in the brake reservoir tank. If fluid level is low, refill the brake fluid.

2.

Check for leakage in brake piping and around VDC/TCS/ABS actuator. If leakage or seepage is found,
check as follows.

●

If ABS actuator and electric unit (control unit) connector is loose, tighten piping to specified torque.
Then inspect again and confirm that there is no leakage.

●

If connection of flare nuts or screws of VDC/TCS/ABS actuator are damaged, replace damaged parts.
Then inspect again and confirm that there is no leakage.

●

If there is leakage or seepage at any location other than VDC/TCS/ABS actuator connections, wipe
away leakage or seepage with clean cloth. Then inspect again and confirm that there is no leakage.

●

If there is leakage from VDC/TCS/ABS actuator, wipe away leakage or seepage with clean cloth. Then
inspect again. If there is leakage or seepage, replace VDC/TCS/ABS actuator unit.

CAUTION:

ABS actuator body cannot be disassembled.

3.

Check brake disc rotor and pads and brake drum and linings. Refer to 

MA-42, "Checking Disc Brake"

  and

MA-42, "Checking Drum Brake"

 .

BASIC INSPECTION 2: INSPECTION FOR LOOSENESS OF POWER SYSTEM TERMINALS

Check cables for looseness on the battery positive/negative terminals and ground connection. If looseness is
detected, tighten the cables to the specified torque. Check that the battery voltage does not drop and the gen-
erator is normal.

BASIC INSPECTION 3: INSPECTION OF ABS WARNING LAMP, VDC OFF INDICATOR LAMP, 
AND SLIP INDICATOR LAMP

1.

Check that ABS warning lamp illuminates for approximately 2 seconds when ignition switch is turned ON.
If it does not illuminate, inspect ABS warning lamp and circuit, and inspect combination meter. Refer to

BRC-66, "Wiring Diagram — VDC —"

 .

2.

Check that VDC OFF indicator lamp illuminates for approximately 2 seconds when ignition switch is
turned ON. If it does not illuminate, inspect VDC OFF indicator lamp and circuit, and inspect combination
meter. Refer to 

BRC-66, "Wiring Diagram — VDC —"

 .

3.

Check that SLIP indicator lamp illuminates for approximately 2 seconds when ignition switch is turned ON.
If it does not turn on, check SLIP indicator lamp and circuit and combination meter. Refer to 

BRC-66, "Wir-

ing Diagram — VDC —"

 .

4.

With engine running, turn VDC OFF switch ON and OFF. Check that VDC OFF indicator lamp turns ON
and OFF. If indicator lamp does not turn ON and OFF according to switch operation, inspect VDC OFF
switch and circuit and combination meter. Refer to 

BRC-66, "Wiring Diagram — VDC —"

TROUBLE DIAGNOSIS

Inspection 1 Wheel Sensor System

EFS003I8

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-128, "Front Sensor Rotor"

  or 

BRC-129, "Rear Sensor Rotor"
