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.

2: With LDP models.

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, VDC OFF indicator lamp, SLIP indicator

lamp and brake warning lamp are ON.

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

during active test.

• Erase memory of ICC system after implementing active test. Refer to 

CCS-24, "CONSULT-III Function

(ICC)"

.

• Erase memory of the lane camera unit after implementing active test. Refer to 

CCS-130, "CONSULT-

III Function (LANE CAMERA)"

.

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.

Test Item

ABS SOLENOID VALVE

• Touch “Up”, “Keep” and “Down”. Then use screen monitor to check that solenoid valve operates as shown in

the table below.

*: On for 1 to 2 seconds after the touch, 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)

• Touch “Up”, “ACT UP” and “ACT KEEP”. Then use screen monitor to check that solenoid valve operates as

shown in the table below.

*: On for 1 to 2 seconds after the touch, 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 MOTOR

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

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.
