CONSULT-II Functions (BCM)
EKS00Q7O
CONSULT-II can display each diagnostic item using the diagnostic test mode shown following.
CONSULT-II BASIC OPERATION
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 the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the 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".

AUTO LIGHT SYSTEM
When ignition switch is turned to ON position and when outside brightness is darker than prescribed level,
input is supplied
lto BCM terminal 24
lfrom light and rain sensor terminal 2.
The headlamps will then illuminate. For a description of headlamp operation, refer toLT-49, "
System Descrip-
tion".
COMBINATION SWITCH READING FUNCTION
Refer toBCS-3, "COMBINATION SWITCH READING FUNCTION".
CAN Communication System DescriptionEKS00Q7X
Refer toLAN-23, "CAN COMMUNICATION".
Major Components and FunctionsEKS00Q7Y
Components Functions
BCM
lTurns ON/OFF circuits of tail light and headlamp according to signals from light and rain sensor, lighting switch
(AUTO), driver door switch, passenger door switch, rear door switches, back door switch, glass hatch opener
switch and ignition switch (ON, OFF).
Light and rain
sensor
lConverts outside brightness (lux) to voltage, and sends it to BCM. (Detects lightness of 50 to 1,300 lux.)
