CONSULT-II MAIN FUNCTION

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

CONSULT-II SETTING PROCEDURE

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 performs CAN communication.

●

For further information, see the CONSULT-II Operation Manual.

Turn ignition switch “OFF”.

Connect CONSULT-II and CONSULT-II CONVERTER to data
link connector on vehicle.

Turn ignition switch “ON”.

Touch “START (NISSAN BASED VHCL)”.

Touch “ABS”.
If “ABS” is not indicated, go to

SELF-DIAG RESULT MODE
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 SETTING PROCEDURE”. Refer to

BRC-20, "CONSULT-II SETTING PROCE-

DURE"

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:

Just after starting engine, or turning ignition switch ON, “ABS” may not be displayed on system
selection screen even if “START (NISSAN BASED VHCL)” is touched. In this case, start self-diag-
nosis again from step 2. If it cannot be shown after several attempts, ABS actuator and electric
unit (control unit) may have malfunctioned. Repair or replace control unit.

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-28, "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.

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.

Symptom

Symptom description

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.

Normal

ABS operation (longer stop-
ping distance)

Stopping distance may be longer for vehicles with ABS when the vehicle
drives on rough or snow-covered roads. Use lower speeds when driving on
these kinds of roads.
