[TYPE 2]
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).

DTC CONFIRMATION PROCEDURE
1.
CHECK SELF-DIAGNOSIS RESULTS
Check the self-diagnosis results.
Is above displayed on the self-diagnosis display?
YES
>> Proceed to diagnosis procedure. Refer to
BRC-100, "Diagnosis Procedure"
.
NO
>> Inspection End
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.
1.
CONNECTOR INSPECTION
1.
Disconnect the ABS actuator and electric unit (control unit) connector and wheel sensor of malfunctioning
code.
2.
Check the terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?
YES
>> GO TO 2
NO
>> 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:
DTC

Malfunction detected condition
Possible cause
C1101
RR RH SENSOR-1
Circuit of rear RH wheel sensor is open. Or when the sen-
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.
C1104
FR LH SENSOR-1
Circuit of front LH wheel sensor is open. Or when the

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-178, "Removal and Installation"
.
3.
CHECK TIRES
Check the inflation pressure, wear and size of each tire.
Is the inspection result normal?
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),
Is the inspection result normal?
YES
>> GO TO 5
NO
>> Repair or replace as necessary. Refer to
FAX-8, "Removal and Installation"
(C200 rear), or
RAX-23, "Removal and Installation"
(M226 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 connector terminals
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) connector and the malfunctioning
wheel sensor connector.
Is the inspection result normal?
Continuity should not exist.
