NOTE:

A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is a oper-
ation for checking.

ACTIVE TEST MODE

CAUTION:

• Never 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, VDC OFF indicator lamp, SLIP indicator

lamp and brake warning lamp is 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” in “ABS” with CONSULT-III is displayed 10 seconds after operation start.
• After “TEST IS STOPPED” in “ABS” with CONSULT-III is displayed, to perform test again.

Test Item

ABS SOLENOID VALVE

• Select “Up”, “Keep” and “Down” of “ACTIVE TEST” in “ABS” with CONSULT-III. Then use screen monitor to

check that solenoid valve operates as shown in the table below.

*: On for 1 to 2 seconds after the select, and then Off.

NOTE:

A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is a
operation for checking.

ABS SOLENOID VALVE (ACT)

• Select “Up”, “ACT UP” and “ACT KEEP” of “ACTIVE TEST” in “ABS” with CONSULT-III. Then use screen

monitor to check that solenoid valve operates as shown in the table below.

DTC/CIRCUIT DIAGNOSIS

C1101, C1102, C1103, C1104 WHEEL SENSOR

Description

INFOID:0000000005517271

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 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 self-diagnosis for “ABS” with CONSULT-III.

Is DTC “C1101”, “C1102”, “C1103” or “C1104” detected?

YES

>> Proceed to diagnosis procedure. Refer to 

BRC-33, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000005517273

CAUTION:

Never check between wheel sensor harness connector terminals.

1.

CHECK TIRE

Check air pressure, wear, and size. Refer to 

WT-60, "Tire Air Pressure"

.

Is the inspection result normal?

YES

>> GO TO 2.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace error-detected parts.

5.

REPLACE WHEEL SENSOR

1.

Replace wheel sensor.

2.

Erase self-diagnosis results for “ABS” with CONSULT-III.

4.

Perform self-diagnosis for “ABS” with CONSULT-III.

Is DTC “C1101”, “C1102”, “C1103” or “C1104” detected?

YES

Component Inspection

INFOID:0000000005517274

1.

CHECK DATA MONITOR

Select “ABS”, “DATA MONITOR” in order with CONSULT-III, select “FR LH SENSOR”, “FR RH SENSOR”,
“RR LH SENSOR”, and “RR RH SENSOR”, and check the vehicle speed.
