CONSULT-II INSPECTION 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 carry out CAN communication.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to the
data link connector.
3. Turn ignition switch ON.

Note 1: After completing repairs of shorted sensor circuit, when ignition switch is turned ON, ABS warning lamp turns on. Make sure that
ABS warning lamp turns off while driving vehicle at 30 km/h (19 MPH) or more for approximately 1 minute according to self-diagnosis
procedure. In addition, if wheel sensor 2 is displayed for wheels, check wheel sensor circuit and also check control unit power voltage.

OPERATION PROCEDURE
1. Touch “START (NISSAN BASED VHCL)”, “ABS”, “DATA MONITOR” in order on CONSULT-II screen.
CAUTION:
When “START (NISSAN BASED VHCL)” is touched immediately after starting engine or turning on
ignition switch, “ABS” might not be displayed in “SELECT SYSTEM” screen. In this case, repeat
the operation from step 1.
2. At the monitor item selection screen, touch one of the item “ECU INPUT SIGNALS”, “MAIN SIGNALS” or
“SELECTION FROM MENU”.
3. Touch “START” to proceed to the data monitor screen.
DISPLAY ITEM LIST
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.

6.CHECK WHEEL SENSOR
1. Replace wheel sensor that resulted in malfunction by self-diagnosis.
2. Reconnect connectors, drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute, and then
perform self-diagnosis.
Is above displayed on self-diagnosis display?
OK >> Wheel sensor has malfunction.
NG >>
lReplace ABS actuator and electric unit (control unit).
lPerform to self-diagnosis again, and make sure that the result shows “NO DTC IS DETECTED.
FURTHER TESTING MAY BE REQUIRED”.

2.CHECK CONNECTOR
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector E63 check
terminal for deformation, disconnection, looseness, and so on. If there is an error, repair or replace termi-
nal.
2. Connect the connector securely and perform self-diagnosis again.
OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 3.
3.CHECK ABS ACTUATOR RELAY OR ABS MOTOR RELAY POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector E63.
2. Check voltage between ABS actuator and electric unit (control
unit) harness connector E63 and ground.
OK or NG
OK >> GO TO 4.
NG >> Circuit malfunction between battery and ABS actuator and electric unit (control unit). Repair the
circuit.
4.CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT
Check continuity between ABS actuator and electric unit (control
unit) harness connector E63 and ground.
OK or NG
OK >> Perform self-diagnosis again. If the same results appear, replace ABS actuator and electric unit
(control unit).
NG >> Open or short in harness. Repair or replace harness.
