CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.

CONSULT-II SETTING PROCEDURE

Refer to

GI-37, "CONSULT-II Start Procedure"

Self-Diagnosis

NFS000T0

DESCRIPTION

If an error is detected in system, ABS warning lamp and brake warning lamp on combination meter turns on. In
this case, perform self-diagnosis as follows.

OPERATION PROCEDURE

Perform “CONSULT-II Start Procedure”. Refer to

GI-37, "CONSULT-II Start Procedure"

Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute.

Stop vehicle. With engine at idle, touch “SELF-DIAG RESULTS”. Display shows malfunction experienced
since the last erasing operation.

CAUTION:

If START (NISSAN BASED VHCL) is touched immediately after starting engine or turning on the
ignition switch, ABS might not be displayed in the SELECT SYSTEM screen. In this case, repeat
the operation from step 1.

Self-diagnosis results are displayed. (If necessary, touch “PRINT” to print self-diagnosis result.)

●

When “NO FAILURE” is shown, check ABS warning lamp. Refer to

BRC-26, "For Fast and Accurate

Diagnosis"

●

CONSULT-II self-diagnosis results are displayed without regard to occurrence timing. In some cases
later ones (timing value is small) appear on next screen.

Go to appropriate “Inspection” chart according to “Display Item List”, and repair or replace as necessary.

Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute.

CAUTION:

●

Check again to make sure that there is no malfunction on other parts.

For Fast and Accurate Diagnosis

PRECAUTIONS FOR DIAGNOSIS

●

Before performing trouble diagnosis, always read general information (GI) to confirm general precautions.
Refer to

GI-4, "General Precautions"

●

After completing service, always erase self-diagnosis results. Refer to

BRC-20, "CONSULT- II Functions

(ABS)"

●

When inspection of continuity or voltage between units is performed, check connector terminals for dis-
connection, looseness, bends, or collapses. If any non-standard condition is detected, repair or replace
applicable part.

●

Intermittent errors may be caused by a poor connection in harness, connector, or terminal. Move har-
nesses, harness connectors, or terminals by hand to make sure all connections are solid and undamaged.

●

If a circuit tester is used for check, be careful not to forcibly extend any connector terminal.

●

ABS is a system that uses electronic control to perform brake control. Therefore, phenomena like those
shown in the following table may occur, but this is because system is working normally.

●

To use CONSULT-II to perform self-diagnosis of ABS actuator and electric unit (control unit), active tests,
or work support, first stop work, then connect CONSULT-II and select “ABS”.

●

When CONSULT-II is used, ABS warning lamp may be ON/OFF.

Basic Inspection

NFS000FI

BRAKE FLUID LEVEL, LEAKS, AND BRAKE PAD

Check fluid level in the brake reservoir tank. If fluid level is low, refill brake fluid.

Check brake piping and around ABS actuator and electric unit (control unit) for leaks. If leakage or seep-
age is found, check the following items.

●

If ABS actuator and electric unit (control unit) connection is loose, tighten piping to the specified torque
and re-conduct the leak inspection to make sure there are no leakage.

●

If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw,
replace the damaged part and re-conduct the leak inspection to make sure there are no leakage.

●

If there is leakage or seepage at any location other than ABS actuator and electric unit (control unit)
connection, wipe away leakage or seepage with clean cloth. Then inspect again and confirm than there
is on leakage.

●

If there is leakage from ABS actuator and electric unit (control unit), wipe away leakage or seepage with
clean cloth. Then inspect again. If there is leakage or seepage, replace ABS actuator and electric unit
(control unit).

CAUTION:

ABS actuator and electric unit (control unit) body can not be disassembled.

Check the brake disc rotor and pads. Refer to

BR-28, "Removal and Installation of Brake Pad"

in “Front

Disc Brake” and

BR-34, "Removal and Installation of Brake Pad"

in “Rear Disc Brake”.

POWER SYSTEM TERMINAL LOOSENESS AND BATTERY

Make sure battery positive cable, negative cable and ground connection are not loose. If looseness is
detected, tighten the piping to the specified torquer. In addition, check the battery voltage to make sure it has
not dropped and alternator is normal.

Symptom

Result

Motor operation noise

This is the noise of motor operating inside ABS actuator and electric unit
(control unit). Slight noise may occur during ABS operation.

Normal

Just after the engine starts, the motor operating noise may be heard. This is
a normal status of the system operation check.

System operation check
noise

When the engine is started, you may barely be able to hear a slight thudding
sound from the engine room, but this sound is made by the system operation
check and is normal.

After using CONSULT-II SELF-DIAG RESULTS to determine position of malfunctioning wheel sensor, check
all areas to determine the component to be replaced.

CAUTION:

●

Do not measure resistance value and also voltage between sensor terminal with tester etc.,
because sensor is an active sensor.

●

Do not expand terminal of connector with a tester terminal stick, when it does inspection with
tester.

Disconnect ABS actuator and electric unit (control unit) connector E24 and malfunctioning wheel sensor
connector E20 (FR - LH) or E27 (FR - RH) or B202 (RR - LH), B203 (RR - RH). Check terminal to see if it
is deformed, disconnected, loose, etc., and repair or replace it if any malfunction condition is found.

INSPECTION PROCEDURE

CHECK SELF-DIAGNOSIS RESULTS

Check self-diagnostic results.

Is above displayed in self-diagnosis display?

YES

>> GO TO 2.

>> INSPECTION END

CHECK CONNECTOR

Turn ignition switch “OFF”.

Disconnect ABS actuator and electric unit (control unit) connector E24. Then reconnect it securely.

Preform self-diagnosis again.

DO any self-diagnosis items appear?

YES

>> GO TO 3

>> Poor connection. Repair or replace the applicable connector.

CHECKING ABS MOTOR AND MOTOR RELAY POWER SYSTEM

Turn ignition switch “OFF”.

Disconnect ABS actuator and electric unit (control unit) connector.

Check voltage between ABS actuator and electric (control unit)
unit harness connector E24 and ground.

Check continuity between ABS actuator and electric unit (control
unit) harness connector E24 and ground.

OK or NG

>> Perform self-diagnosis again. If the same result

appears, replace ABS actuator and electric unit (control
unit). Refer to

BRC-42, "ACTUATOR AND ELECTRIC

UNIT (ASSEMBLY)"

>> Repair harness or connectors.
