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.

NOTE:
The example shown is for front right wheel. The procedure for the other wheels is the same as given below.
1. For ABS solenoid valve, touch “UP”, “KEEP”, and “DOWN” on
the display screen. Make sure solenoid valve operates as
shown in solenoid valve operation chart.

TROUBLE DIAGNOSIS
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”.
Inspection 2 ABS Actuator and Electric Unit (Control Unit)EFS005U0
INSPECTION PROCEDURE
1.CHECK SELF-DIAGNOSTIC RESULTS
Check self-diagnostic results.
Is above displayed in self-diagnosis display items?
YES >> Replace ABS actuator and electric unit (control unit). Perform ABS actuator and electric unit (con-
trol unit) self-diagnosis again.
NO >> INSPECTION END

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.

Fuel Injection Control SystemEBS01KCE
SYSTEM DESCRIPTION
Three types of fuel injection control are provided to accommodate engine operating conditions; normal control,
idle control and start control. The ECM determines the appropriate fuel injection control. Under each control,
the amount of fuel injected is adjusted to improve engine performance.
Pulse signals are sent to fuel injectors according to the input signals to adjust the amount of fuel injected to
preset value.
