2. Are there any self-diagnostic items, other than those relating to CAN communication system, in the self-
diagnosis results?

If YES, GO TO 3.

If NO, GO TO 4.
3. Based on self-diagnosis results unrelated to CAN communication, carry out the inspection.
4. Malfunctions may be detected in self-diagnosis depending on control units carrying out CAN communica-
tion. Therefore, erase the self-diagnosis results.
5. Diagnose CAN communication system. Refer to LAN-44, "
TROUBLE DIAGNOSIS" .
Precautions for Brake ControlEFS006LA

During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.

Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from
engine compartment. This is normal due to the self check operation.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.

When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnosis. Besides electrical system inspection, check brake booster operation, brake fluid level, and fluid
leaks.

If incorrect tire sizes or types are installed on the vehicle or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.

If there is a radio, antenna or related wiring near the control module, ABS function may have a malfunction
or error.

If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits or improper wiring.
Precautions for CAN SystemEFS006LB

Do not apply voltage of 7.0V or higher to terminal to be measured.

Maximum open terminal voltage of tester in use must be less than 7.0V.

Before checking harnesses, turn ignition switch OFF and disconnect battery negative cable.

Area to be repaired must be soldered and wrapped with tape.
Make sure that fraying of twisted wire is within 110 mm (4.33 in).

Do not make a bypass connection to repaired area. (If the circuit
is bypassed, characteristics of twisted wire will be lost.)

Basic InspectionEFS006LM
BRAKE FLUID LEVEL, FLUID LEAK, AND BRAKE PAD INSPECTION
1. Check fluid level in the brake fluid reservoir. If fluid level is low, add fluid.
2. Check the brake piping and around the ABS actuator and electric unit (control unit) for leaks. If there is
leaking or seeping fluid, check the following items.

If ABS actuator and electric unit (control unit) connection is loose, tighten the piping to the specified
torque and recheck for leaks.

If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) threads,
replace the damaged part and recheck for leaks.

When there is fluid leaking or seeping from a fluid connection, use a clean cloth to wipe off the fluid and
recheck for leaks. If fluid is still seeping out, replace the damaged part. If the fluid is leaking at the ABS
actuator and electric unit (control unit), replace the ABS actuator and electric unit (control unit) assem-
bly.
CAUTION:
The ABS actuator and electric unit (control unit) cannot be disassembled and must be replaced
as an assembly.
3. Check the brake pads for excessive wear.
POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure the battery positive cable, negative cable and ground connection are not loose. In addition, make
sure the battery is sufficiently charged.
ABS WARNING LAMP INSPECTION
1. Make sure ABS warning lamp turns on for approximately 2 seconds when the ignition switch is turned ON.
If it does not, check CAN communications. If there are no errors with the CAN communication system,
replace the combination meter. Refer to IP-19, "
COMBINATION METER" .
2. Make sure the lamp turns off approximately 2 seconds after the ignition switch is turned ON. If the lamp
does not turn off, conduct self-diagnosis of ABS actuator and electric unit (control unit). If no malfunctions
are detected in self-diagnosis, replace combination meter. Refer to IP-19, "
COMBINATION METER" .
3. After conducting the self-diagnosis, be sure to erase the error memory. Refer to BRC-20, "
CONSULT-II
Function (ABS)" .

Note 1: If wheel sensor 2 for each wheel is indicated, check ABS actuator and electric unit (control unit) power supply voltage in addition
to wheel sensor circuit check.
Note 2: If multiple malfunctions are detected including CAN communication line [U1000], perform diagnosis for CAN communication line
first.
DATA MONITOR
Operation Procedure
1. After turning OFF the ignition switch, connect CONSULT-II and the CONSULT-II CONVERTER to the data
link connector.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
2. Touch “START (NISSAN BASED VHCL)”, “ABS”, “DATA MONITOR” in order on the CONSULT-II screen.
If “ABS” is not indicated, go to GI-40, "

NOTE:
The green POWER indicator should illuminate. If the POWER indicator does not illuminate, replace the
battery in the ABS active wheel sensor tester before proceeding.
3. Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel
sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal.
NOTE:
If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and
retest.
Does the ABS active wheel sensor tester detect a signal?
YES >> GO TO 3.
NO >> Replace the wheel sensor. Refer to BRC-33, "
Removal and Installation" .
3. CHECK TIRES
Check for inflation pressure, wear and size of each tire. Refer to WT-29, "
SERVICE DATA AND SPECIFICA-
TIONS (SDS)" .
Are tire pressure and size correct and is tire wear within specifications?
YES >> GO TO 4.
NO >> Adjust tire pressure or replace tire(s).
4. CHECK WHEEL BEARINGS
Check wheel bearing axial end play. Refer to FAX-5, "
FRONT WHEEL BEARING INSPECTION" or RAX-4,
"REAR WHEEL BEARING INSPECTION" .
OK or NG
OK >> GO TO 5.
NG >> Repair or replace as necessary. Refer to FAX-5, "
