DIAGNOSIS SYSTEM [ABS ACTUATOR AND ELECTRIC UNIT (CONTROL

UNIT)]

CAUTION:

• Do not perform active test while driving vehicle.
• Make sure to completely bleed air from brake system.
• The active test cannot be performed with the ABS warning lamp, VDC OFF indicator lamp, SLIP indi-

cator lamp or brake warning lamp on.

• ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp are on

during active test.

NOTE:
• When active test is performed while depressing the pedal, the pedal depression amount will change. This is

normal. (Only solenoid valve and ABS motor.)

• “TEST IS STOPPED” is displayed 10 seconds after operation start.
• After “TEST IS STOPPED” is displayed, to perform test again, touch BACK.

Test Item

SOLENOID VALVE

• When performing an active test of the ABS function, select the “MAIN SIGNALS” for each test item. In addi-

tion, when performing an active test of the VDC/TCS function, select the item menu for each test item.

• For ABS solenoid valve, touch “Up”, “Keep”, and “Down” on the display screen. For ABS solenoid valve

(ACT), touch “Up”, “ACT UP”, “ACT KEEP” and confirm that solenoid valves operate as shown in the table
below.

*: ON for 1 to 2 seconds after the touch, and then OFF

ABS MOTOR

• Touch “On” and “Off” on screen. Make sure motor relay and actuator relay operates as shown in table below.

Description

INFOID:0000000005548242

When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current
signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).

Diagnosis Procedure

INFOID:0000000005548244

Regarding Wiring Diagram information, refer to

BRC-154, "Wiring Diagram - BRAKE CONTROL SYSTEM -

WITHOUT HILL DESCENT CONTROL/HILL START ASSIST"

CAUTION:

Do not check between wheel sensor terminals.

CONNECTOR INSPECTION

Disconnect the ABS actuator and electric unit (control unit) connector and wheel sensor of malfunctioning
code.

Check the terminals for deformation, disconnection, looseness or damage.

Is the inspection result normal?

YES

>> GO TO 2

>> Repair or replace as necessary.

CHECK WHEEL SENSOR OUTPUT SIGNAL

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

Turn on the ABS active wheel sensor tester power switch.
NOTE:

sor power voltage is outside the standard.

• Harness or connector
• Wheel sensor
• ABS actuator and electric unit

(control unit)

C1102

RR LH SENSOR-1

Circuit of rear LH wheel sensor is open. Or when the sen-
sor power voltage is outside the standard.

C1103

FR RH SENSOR-1

Circuit of front RH wheel sensor is open. Or when the
sensor power voltage is outside the standard.

BRC

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.

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

>> Replace the wheel sensor. Refer to

BRC-178, "Removal and Installation"

CHECK TIRES

Check the inflation pressure, wear and size of each tire.

Is the inspection result normal?

YES

>> GO TO 4

>> Adjust tire pressure or replace tire(s).
