Control Unit Circuit Test
System Description:When the switch is ON, the control unit lights up the lamp.
INPUT-OUTPUT VOLTAGE CHART
The voltage value is based on the body ground.
*:If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltage. Control unit
does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not supply power to light up the
lamp.
INPUT-OUTPUT VOLTAGE CHART
The voltage value is based on the body ground.
*:If high resistance exists in the switch side circuit (caused by a single strand), terminal 2 does not detect approx. 0V. Control unit does
not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not control ground to light up the lamp.

PRECAUTIONS
lNever reverse polarity of battery terminals.
lInstall only parts specified for a vehicle.
lBefore replacing the control unit, check the input and output and
functions of the component parts.
lDo not apply excessive force when disconnecting a connector.
lIf a connector is installed by tightening bolts, loosen bolt mount-
ing it, then take it out by hand.
lBefore installing a connector, make sure the terminal is not bent
or damaged, and then correctly connect it.
When installing a connector by tightening bolts, fix it by tighten-
ing the mounting bolt until the painted projection of the connec-
tor becomes even with the surface.
lFor removal of the lever type connector, pull the lever up to the
direction pointed to by the arrow A in the figure, and then
remove the connector.
lFor installation of the lever type connector, pull down the lever to
the direction pointed by the arrow B in the figure, and then push
the connector until a clicking noise is heard.

lDo not apply excessive shock to the control unit by dropping or
hitting it.
lBe careful to prevent condensation in the control unit due to
rapid temperature changes and do not let water or rain get on it.
If water is found in the control unit, dry it fully and then install it in
the vehicle.
lBe careful not to let oil to get on the control unit connector.
lAvoid cleaning the control unit with volatile oil.
lDo not disassemble the control unit, and do not remove the
upper and lower covers.
lWhen using a DMM, be careful not to let test probes get close to
each other to prevent the power transistor in the control unit
from damaging battery voltage because of short circuiting.
lWhen checking input and output signals of the control unit, use
the specified check adapter.

Configuration (BCM)EAS001Q6
DESCRIPTION
CONFIGURATION has two functions as follows:
lREAD CONFIGURATION is the function to confirm vehicle configuration of current BCM.
lWRITE CONFIGURATION is the function to write vehicle configuration on BCM.
CAUTION:
lWhen replacing BCM, you must perform WRITE CONFIGURATION with CONSULT-II.
lComplete the procedure of WRITE CONFIGURATION in order.
lIf you set incorrect WRITE CONFIGURATION, incidents will occur.
lConfiguration is different for each vehicle model. Confirm configuration of each vehicle model.
READ CONFIGURATION 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. With ignition switch OFF, connect CONSULT-II and CONSULT-II
CONVERTER to data link connector, and then turn ignition
switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “BCM” on “SELECT SYSTEM” screen.
If “BCM” is not indicated, refer toGI-50, "
CONSULT-II Data Link
Connector (DLC) Circuit"in “GI” section.
