CONSULT-II MAIN FUNCTION
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II SETTING PROCEDURE
Refer to GI-34, "CONSULT-II Start Procedure" .
Self-Diagnosis BFS000D0
DESCRIPTION
If an error is detected in the system, ABS warning lamp on combination meter turn on. In this case, perform
self- diagnosis as follows.
OPERATION PROCEDURE
1. Turn ignition switch OFF.
2. Perform “CONSULT-II Starting Procedure”. Refer to GI-34, "
CONSULT-II Start Procedure" .
3. Turn ignition switch ON.
4. Start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
5. After stopping vehicle, with the engine running, touch “ABS”, “SELF-DIAG RESULTS” in order on the
CONSULT-II screen.
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 System Selection screen. In this case, repeat
the operation from step 1. If it cannot be shown after several attempts, ABS actuator and electric
unit (control unit) may have malfunctioned.
6. The self-diagnostic results are displayed. (Touch “PRINT” to print out self-diagnostic results, if necessary.)
Check ABS warning lamp if “NO FAILURE” is displayed.
7. Perform the appropriate inspection from the display item list, and repair or replace the malfunctioning
component.
8. Start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
CAUTION:
When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning
lamp will not turn off even when the system is normal unless the vehicle is driving at approxi-
mately 30 km/h (19 MPH) or more for approximately 1 minute.
ERASE MEMORY
1. Turn ignition switch OFF.
2. Start engine and touch “ABS”, “SELF-DIAG RESULTS”, “ERASE MEMORY” in order on the CONSULT-II
screen to erase the error memory.
CAUTION:
If the error memory is not erased, re-perform the operation from step 4.
3. Perform self-diagnosis again, and make sure that diagnostic memory is erased.
4. Drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make
sure that the ABS warning lamp is off.
Diagnostic test mode Function Reference
SELF-DIAG RESULTS Self-diagnostic results can be read and erased quickly.BRC-17, "

sis"
DATA MONITOR Input/Output data in the ABS actuator and electric unit (control unit) can be read.BRC-19, "Data Monitor"
CAN DIAG SUPPORT
MNTRThe results of transmit/receive diagnostic of CAN communication can be read.LAN-44, "CAN Diagnos-
tic Support Monitor"
ACTIVE TESTDiagnostic Test Mode in which CONSULT-II drives some actuators apart from
the ABS actuator and electric unit (control unit) and also shifts some parameters
in a specified range.BRC-20, "Active Test"
FUNCTION TESTPerformed 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. —
