ASKING COMPLAINTS

Complaints against malfunction vary depending on each person.
It is important to clarify customer complaints.

Ask customer about what symptoms are present and under
what conditions. Use information to reproduce symptom while
driving.

It is also important to use diagnosis sheet so as not to miss infor-
mation.

Control Unit Input/Output Signal StandardNFS00022
REFERENCE VALUE FROM CONSULT-III
CAUTION:
The display shows the control unit calculation data, so a normal value might be displayed even in the
event the output circuit (harness) is open or short - circuited.
Note 1: Confirm tire pressure is normal.
Note 2: Serves as EBD warning lamp.
Note 3: ON/OFF timing of ABS warning lamp
ON: For approximately 1 second after the ignition switch is turned on or when an error is detected.
OFF: Approximately 1 second after the ignition switch is turned on (when system is normal).Monitor item Display ContentData monitor

CONSULT- II Functions (ABS)NFS00023
CONSULT-III MAIN FUNCTION
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
Self-DiagnosisNFS000HD
OPERATION PROCEDURE
1. Before performing the self-diagnosis, start engine and drive vehicle at 30 km/h (19 MPH) or more for
approximately 1 minute.
HOW TO ERASE SELF-DIAGNOSIS RESULTS
1. After erasing DTC memory, start engine and 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 and brake warning lamp turn
OFF.
CAUTION:
If memory cannot be erased, perform applicably diagnosis.

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 approximately 30 km/h (19 MPH) or more for approximately 1 minute.

Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake
fluid level switch operation (when brake fluid is insufficient).
Diagnostic test mode Function Reference
SELF-DIAG RESULTS Self-diagnostic results can be read and erased quickly.BRC-19, "
Self-Diagnosis"
DATA MONITORInput/Output data in the ABS actuator and electric unit (control unit) can be
read.BRC-21, "Data Monitor"
CAN DIAG SUPPORT
MNTRThe results of transmit/receive diagnosis of communication can be read.LAN-44, "CAN Diagnostic
Support Monitor"
ACTIVE TESTDiagnostic Test Mode in which CONSULT-III drives some actuators apart
from the ABS actuator and electric unit (control unit) and also shifts some
parameters in a specified range.BRC-22, "Active Test"
FUNCTION TESTConducted by CONSULT-III 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. —
