NOTE:
• 1: The CONSULT will display DDS (Downhill Drive Support) when referring to the Hill Descent Control system.
• 2: The CONSULT will display USS (Uphill Start Support) when referring to the Hill Start Assist system.

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 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.
