[ABS]
DIAGNOSIS SYSTEM [ABS ACTUATOR AND ELECTRIC UNIT (CONTROL
UNIT)]
NOTE:
1: A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is an
operation for checking.
ACTIVE TEST
CAUTION:
• Do not perform active test while driving vehicle.
• Make sure to completely bleed air from brake system.
• The active test cannot be started when ABS warning lamp and brake warning lamp are ON.
• ABS warning 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.

C1101, C1102, C1103, C1104 WHEEL SENSOR
COMPONENT DIAGNOSIS
C1101, C1102, C1103, C1104 WHEEL SENSOR
Description
INFOID:0000000003766731
When the sensor rotor rotates, the magnetic field changes. Wheel sensor converts the magnetic field changes
to current signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).
DTC Logic
INFOID:0000000003766732
DTC DETECTION LOGIC
DTC CONFIRMATION PROCEDURE
1.
DTC REPRODUCTION PROCEDURE
1.
Start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
2.
Perform ABS actuator and electric unit (control unit) self-diagnosis.
Is DTC “C1101”, “C1102”, “C1103” or “C1104” detected?
YES
>> Proceed to diagnosis. Refer to
.
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000003766733
CAUTION:
Do not check between wheel sensor terminals.
1.
CHECK TIRES
Check air pressure, wear and size. Refer to
.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace damaged parts.
2.
CHECK SENSOR AND SENSOR ROTOR
• Check sensor rotor for damage.
• Check wheel sensor for damage, disconnection or looseness.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair wheel sensor mount or replace sensor rotor. Then perform the self-diagnosis.
3.
CHECK CONNECTOR
1.
Turn the ignition switch OFF.
2.
Disconnect ABS actuator and electric unit (control unit) connector.
3.
Disconnect malfunctioning wheel sensor connector.
4.
Check terminal to see if it is deformed, disconnected, looseness, etc.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Repair or replace damaged parts.

CHECK WHEEL SENSOR HARNESS
1.
Check the continuity between ABS actuator and electric unit (control unit) harness connector and wheel
sensor harness connector. (Also check continuity when steering wheel is turned right and left and when
sensor harness inside the wheel house is moved.)
Measurement terminal for power supply circuit
Measurement terminal for signal circuit
2.
Check the continuity between ABS actuator and electric unit (control unit) harness connector.
Is the inspection result normal?
YES
>> GO TO 5.
NO
>> Repair or replace damaged parts.
5.
CHECK WHEEL SENSOR POWER SUPPLY CIRCUIT
1.
Connect ABS actuator and electric unit (control unit) connector.
2.
Turn the ignition switch ON.
CAUTION:
Never start the engine.
3.
Check the voltage between wheel sensor harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 6.
NO
>> Repair or replace damaged parts.
6.
CHECK DATA MONITOR
1.
Turn the ignition switch OFF.
2.
Connect each wheel sensor connector.
