CONSULT-II Function (ABS)

EFS004N2

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

CONSULT-II BASIC OPERATION PROCEDURE

Turn ignition switch OFF.

Connect CONSULT-II and 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-diag-
nosis depending on control unit which carries out CAN
communication.

Turn ignition switch ON.

Touch “START (NISSAN BASED VHCL)”.

Touch “ABS” in the “SELECT SYSTEM” screen.
If “ABS” is not indicated, go to

GI-38, "CONSULT-II Data Link

Connector (DLC) Circuit"

Select the required diagnostic location from the “SELECT DIAG MODE” screen.
For further information, see the CONSULT-II Operation Manual.

ABS diagnostic mode

Description

WORK SUPPORT

Supports inspection and adjustments. Commands are transmitted to the ABS actuator and electric
unit (control unit) for setting the status suitable for required operation, input/output signals are
received from the ABS actuator and electric unit (control unit) and received data is displayed.

SELF-DIAG RESULTS

Displays ABS actuator and electric unit (control unit) self-diagnosis results.

DATA MONITOR

Displays ABS actuator and electric unit (control unit) input/output data in real time.

CAN DIAG SUPPORT MNTR

The result of transmit/receive diagnosis of CAN communication can be read.

ACTIVE TEST

Operation of electrical loads can be checked by sending drive signal to them.

FUNCTION TEST

Conducted by CONSULT-II instead of a technician to determine whether each system is "OK" or
"NG".

ECU PART NUMBER

ABS actuator and electric unit (control unit) part number can be read.

TROUBLE DIAGNOSIS

2005 Pathfinder

SELF-DIAGNOSIS
Description

If an error is detected in the system, the ABS warning lamp will turn on. In this case, perform self-diagnosis as
follows:

Operation Procedure

Turn ignition switch OFF.

Connect CONSULT-II and 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.

Turn ignition switch ON.

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

After stopping the vehicle, with the engine running, touch “START (NISSAN BASED VHCL)”, “ABS”,
“SELF-DIAG RESULTS” in order on the CONSULT-II screen.

CAUTION:

If “START (NISSAN BASED VHCL)” is touched immediately after starting the 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.

The self-diagnostic results are displayed. (If necessary, the self-diagnostic results can be printed out by
touching “PRINT”.)

●

When “NO DTC IS DETECTED” is displayed, check the ABS warning lamp, SLIP indicator lamp and
VDC OFF indicator lamp.

Conduct the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.

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

CAUTION:

●

When a wheel sensor “short-circuit” is detected, if the vehicle is not driven at 30 km/h (19 MPH)
for at least 1 minute, the ABS warning lamp will not turn off even if the malfunction is repaired.

Turn ignition switch OFF to prepare for erasing the memory.

10. Start the engine and touch “START (NISSAN BASED VHCL)”, “ABS”, “SELF-DIAG RESULTS”, “ERASE”

in order on the CONSULT-II screen to erase the error memory.
If “ABS” is not indicated, go to

GI-38, "CONSULT-II Data Link Connector (DLC) Circuit"

CAUTION:

If the error memory is not erased, re-conduct the operation from step 5.

11. For the final inspection, drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute and

confirm that the ABS warning lamp, SLIP indicator lamp, and VDC OFF indicator lamp are off.
