Note: Only AWD models
Active TestNFS000QI
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 indicator lamp, SLIP indica-
tor 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 ACS-34, "Self-Diagnostic
Function" .
OPERATION PROCEDURE
1. Perform “CONSULT-II Starting Procedure”. Refer to GI-38, "CONSULT-II Start Procedure" .
2. Touch “SELECT TEST ITEM” is displayed.
3. Touch necessary test item.
4. While “MAIN SIGNALS” indication is inverted, touch “START”.
5. “ACTIVE TEST” screen will be displayed so perform the following 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” and repeat step 3.

TEST ITEMS
Solenoid Valve
NOTE:
The example shown is for front right wheel. The procedure for the other wheels is the same as given below.

When performing an active test of the ABS function, select the
"MAIN SIGNALS" for each test item. In addition, when perform-
ing 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 (IN,
OUT, USV, HSV) operate 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 actua-
tor 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.
