TROUBLE DIAGNOSIS
ASKING COMPLAINTS
lComplaints against malfunction vary depending on each person.
It is important to clarify customer complaints.
lAsk customer about what symptoms are present and under
what conditions. Use information to reproduce symptom while
driving.
lIt is also important to use the diagnosis sheet so as not to miss
information.

CONSULT- II FunctionsEFS005TT
CONSULT-II MAIN FUNCTION
In a diagnosis function (main function), there are “SELF-DIAG RESULTS”, “DATA MONITOR”, “CAN DIAG
SUPPORT MNTR”, “ACTIVE TEST”, “FUNCTION TEST”, “ECU PART NUMBER”.
CONSULT-II BASIC OPERATION PROCEDURE
1. Touch “ABS” in “SELECT SYSTEM” screen.
2. Select required diagnostic location from “SELECT DIAG MODE”
screen.
Diagnostic
test modeFunction Reference
SELF-DIAG
RESULTSSelf-diagnostic results can be read and erased quickly.BRC-18, "
Self-Diagnosis"
DATA MONI-
TORInput/Output data in the ABS actuator and electric unit (control unit) can be read.BRC-20, "Data Monitor"
CAN DIAG
SUPPORT
MNTRThe results of transmit/receive diagnosis of communication can be read.LAN-15, "CAN Diagnostic
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-21, "Active Test"
FUNCTION
TESTPerformed by CONSULT-II instead of a technician to determine whether each
system is “OK” or “NG”.Separate volume “CON-
SULT-II OPERATION MAN-
UAL (FUNCTION TEST)”

OPERATION PROCEDURE
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector.
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 engine running, touch “START (NISSAN BASED VHCL)”, “ABS”, “SELF-DIAG
RESULTS” in order on CONSULT-II screen.
CAUTION:
If “START (NISSAN BASED VHCL)” is touched immediately after starting engine or turn on the
ignition switch, “ABS” might not be displayed in the “SELECT SYSTEM” screen. In this case,
repeat the operation from step 1.
6. The self-diagnostic results are displayed. (Touch “PRINT” to print out self-diagnostic results, If necessary.)
lCheck ABS warning lamp if “NO FAILURE” is displayed.
7. Perform the appropriate inspection from display item list, and repair or replace the malfunctioning compo-
nent. Refer toBRC-18, "
Display Item List".
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 and brake warning lamp will not turn off even when the system is normal unless the vehicle
is driving at 30 km/h (19MPH) or more for approximately 1 minute.
ERASE MEMORY
1. Turn ignition switch OFF.
2. Start engine and touch “START (NISSAN BASED VHCL)”, “ABS”, “SELF-DIAG RESULTS”, “ERASE
MEMORY” in order on CONSULT-II screen to erase the error memory.
If “ABS” is not indicated, go toGI-50, "
CONSULT-II Data Link Connector (DLC) Circuit".
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 turn off.
