OPERATION PROCEDURE
1. Touch “START (NISSAN BASED VHCL)”, “ABS”, “DATA MONITOR” in order on CONSULT-II screen.
CAUTION:
When “START (NISSAN BASED VHCL)” is touched immediately after starting engine or turning on
the ignition switch, “ABS” might not be displayed in the system selection screen. In this case,
repeat the operation from step 1.
2. At the monitor item selection screen, touch one of the items “ECU INPUT SIGNALS”, “MAIN SIGNALS” or
“SELECTION FROM MENU”.
3. Touch “START” to proceed to the data monitor screen.
DISPLAY ITEM LIST
CAUTION:
The display shows the control unit calculation data, so a normal value might be displayed even in the
event the output circuit (harness) is open or short - circuited.

TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
Note 1: Confirm tire pressure is normal.
Note 2: Only AWD model.
Note 3: 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.
Note 4: On and off timing for warning lamp and indicator lanp.Refer to BRC-33, "
ON and OFF Timing for Warning Lamp and Indicator
Lamp" .
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. 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)
“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.

TROUBLE DIAGNOSIS
Revision: 2006 January2006 M35/M45
Inspection 1: Wheel Sensor CircuitNFS000QL
CAUTION:
Do not check between wheel sensor terminals.
INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSIS RESULTS
Check the self-diagnosis results.
Is above displayed on the self-diagnosis display?
YES >> GO TO 2.
NO >> INSPECTION END
2. CHECK TIRE
Check air pressure, wear and size.
Are air pressure, wear and size within standard?
YES >> GO TO 3.
NO >>
Adjust air pressure, or replace tire.
Perform the self-diagnosis, and make sure that the result shows “NO DTC IS DETECTED”.
3. CHECK SENSOR AND SENSOR ROTOR
Check sensor rotor for damage.
Check wheel sensor for damage, disconnection or looseness.
OK or NG
OK >> GO TO 4.
NG >>
Repair wheel sensor mount or replace sensor rotor. Then perform the self-diagnosis.
Perform the self-diagnosis, and make sure that the result shows “NO DTC IS DETECTED”.
4. CHECK CONNECTOR
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector E30 and
malfunctioning wheel sensor connector E41(FR-RH), E59(FR-LH), B101(RR-RH), B102(RR-LH). Check
terminal to see if it is deformed, disconnected, loose, etc., Repair or replace it if any malfunction condition
is found.
2. Reconnect connectors and then perform the self-diagnosis. Refer to BRC-23, "
OPERATION PROCE-
DURE" .
OK or NG
OK >> INSPECTION END
NG >> GO TO 5.

2. Check continuity between terminals. (Also check continuity
when steering wheel is turned right and left and when sensor
harness inside the wheel house is moved.)
OK or NG
OK >> GO TO 6.
NG >>
Repair or replace malfunctioning components.
Perform the self-diagnosis, and make sure that the result shows “NO DTC IS DETECTED”.
6. CHECK WHEEL SENSOR
1. Replace wheel sensor that resulted in malfunction by self-diagnosis.
2. Reconnect connectors, drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute, and then
perform self-diagnosis.
Is above displayed on the self-diagnosis display?
OK >> INSPECTION END
NG >>
Replace ABS actuator and electric unit (control unit).
Perform the self-diagnosis, and make sure that the result shows “NO DTC IS DETECTED”.
