DIAGNOSIS SYSTEM [ABS ACTUATOR AND ELECTRIC UNIT (CONTROL 

UNIT)]

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

Test Item

ABS SOLENOID VALVE

• Select “Up”, “Keep” and “Down” of “ACTIVE TEST” in “ABS” with CONSULT. 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 an
operation for checking.

ABS SOLENOID VALVE (ACT)

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

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

C1101, C1102, C1103, C1104 WHEEL SENSOR

DTC/CIRCUIT DIAGNOSIS

C1101, C1102, C1103, C1104 WHEEL SENSOR

Description

INFOID:0000000009949919

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.

PRECONDITIONING

If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.

>> GO TO 2.
