CONSULT-II Functions (IPDM E/R)EKS00Q7P
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 carries 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
theignitionswitchON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “IPDM E/R” on “SELECT SYSTEM” screen.
If “IPDM E/R” is not displayed, refer toGI-50, "
CONSULT-II Data
Link Connector (DLC) Circuit".
Diagnosis Mode Description
SELF-DIAGNOSTIC RESULTS Refer toPG-17, "
SELF-DIAGNOSTIC RESULTS".
DATA MONITOR The input/output data of IPDM E/R is displayed in real time.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ACTIVE TEST IPDM E/R sends a drive signal to electronic components to check their operation.

AUTO LIGHT SYSTEMPFP:28491
Component Parts and Harness Connector LocationEKS00Q7V
*1: Without daytime light system, *2: With daytime light system, *3: Double cab, *4: King cab
System DescriptionEKS00Q7W
Automatically turns ON/OFF the parking lamps and the headlamps in accordance with ambient light.
Timing for when the lamps turn ON/OFF can be selected using four modes.
OUTLINE
The auto light system uses an light and rain sensor that detects outside brightness.
When the lighting switch is in AUTO position, it automatically turns ON/OFF the parking lamps and the
headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details of the
setting, refer toLT-60, "
WORK SUPPORT".
Light and rain sensor, power is supplied
lfrom BCM terminal 42
lto light and rain sensor terminal 1.
Light and rain sensor, ground is supplied
lto light and rain sensor terminal 3
lthrough grounds M21, M80 and M83.

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".

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.)
