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. Touch “START (NISSAN BASED VHCL)”, “ABS”, “ACTIVE TEST” in order on the CONSULT-II screen.
CAUTION:
When “START (NISSAN BASED VHCL)” is touched immediately after starting engine or turning on
ignition switch, “ABS” might not be displayed in the "SELECT SYSTEM" screen. In this case,
repeat the operation from step 1.
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)

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.

For Fast and Accurate DiagnosisNFS000QJ
PRECAUTIONS FOR DIAGNOSIS
Before performing diagnosis, always read General Information (GI) to confirm general precautions. Refer
to GI-4, "
General Precautions" .
If steering angle sensor, steering system parts, suspension system parts, ABS actuator and electric unit
(control unit) or tires have been replaced, or if wheel alignment has been adjusted, be sure to adjust neu-
tral position of steering angle sensor before driving. Refer to BRC-6, "
Adjustment of Steering Angle Sen-
sor Neutral Position" .
After diagnosis is finished, be sure to erase memory. Refer to BRC-23, "ERASE MEMORY" .
When checking continuity and voltage between unit, be sure to check for disconnection, looseness, bend,
or collapse of connector terminals. If any malfunction is found, repair or replace connector terminals.
For intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.
If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.
The following symptoms may be caused by normal operations.
Symptom Symptom description Result
Motor operation soundThis is sound of motor inside VDC actuator. Slight sound may occur
during VDC, TCS, and ABS operation.
Normal
Just after engine starts, the motor operating sound may be heard. This
is a normal condition of the system operation check.
System operation check
soundWhen engine starts, slight “click” sound may be heard from engine
room. This is normal and is part of system operation check.Normal
VDC/TCS operation
(SLIP indicator lamp ON)TCS may activate momentarily if wheel speed changes when driving
over location where friction varies, when downshifting, or when fully
depressing accelerator pedal.Normal
Cancel the VDC/TCS
function for the
inspection on a chas-
sis dynamometer. When checking speed meter etc. with a 2-wheel-drive chassis dyna-
mometer, vehicle speed is not increased by pressing down on the accel-
erator.
ABS operation (Longer stop-
ping distance)On roads with low friction, such as snowy roads or gravel roads, vehi-
cles with ABS may require a longer stopping distance. Therefore, when
driving on such roads, avoid overconfidence and keep speed sufficiently
low.Normal
Insufficient feeling of accel-
erationDepending on road conditions, driver may feel that feeling of accelera-
tion is insufficient. This is because traction control, which controls
engine and brakes to achieve optimal traction, has the highest priority
(for safety). As a result, there may be times when acceleration is slightly
less than usual for the same accelerator pedal operation.Normal

Basic InspectionNFS000QK
BASIC INSPECTION 1: BRAKE FLUID LEVEL, LEAK INSPECTION AND BRAKE PAD
1. Check fluid level in brake reservoir tank. If fluid level is low, refill brake fluid. Refer to BR-10, "CHECKING
BRAKE FLUID LEVEL" .
2. Check for leakage in brake tubes or hoses and around ABS actuator and electric unit (control unit). If
there is leaking or seeping fluid, check the following items.
If the brake tube connections at ABS actuator and electric unit (control unit) are loose, tighten flare nuts
to the specified torque. Then inspect again and confirm that there is no leakage.
If flare nuts or screws of ABS actuator and electric unit (control unit) are damaged and loose, replace
damaged parts. Then inspect again and confirm that there is no leakage.
If there is leakage at any location other than ABS actuator and electric unit (control unit) connections,
wipe away leakage with clean cloth. Then inspect again and confirm that there is no leakage.
If there is leakage from ABS actuator and electric unit (control unit), wipe away leakage with clean cloth.
Then inspect again. If there is still leakage, replace ABS actuator and electric unit (control unit).
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake disc rotor and pads. Refer to BR-28, "
DISC ROTOR INSPECTION" (front disc rotor), BR-23,
"PAD WEAR INSPECTION" (front brake pad), BR-34, "DISC ROTOR INSPECTION" (rear disc rotor), BR-
29, "PAD WEAR INSPECTION" (rear brake pad).
BASIC INSPECTION 2: LOOSENESS OF POWER SYSTEM TERMINALS AND BATTERY
Check battery for looseness on battery positive/negative terminals and ground connection. Also make sure
battery voltage does not drop and alternator is normal.
