NOTE:
For navigation system operation information, refer to navigation system owner's manual.
BASIC OPERATION
NOTE:
Locations stored in the Address Book and other memory functions may be lost if the vehicle's battery is disconnected or becomes dis-
charged. If this occurs, service the vehicle's battery as necessary and re-enter the information in the Address Book.
VEHICLE ICON
Symptom Possible cause Possible solution
No image is displayed.The brightness is at the lowest setting. Adjust the brightness of the display.
The display is turns off.
Push and hold to turn on the display.
No voice guidance is available.
The volume is too high or too low.The volume is not set correctly, or it is turned off. Adjust the volume of voice guidance.
Volume guidance is not provided for narrow streets
(roads displayed in gray).This is not a malfunction.
No map is displayed on the screen.The map DVD-ROM is not inserted, or it is inserted
upside down.Insert the map DVD-ROM correctly.
A screen other than map screen is displayed. Push “MAP”.
The screen is too dim.
The movement is slow.The temperature in the interior of the vehicle is low.Wait until the interior of the vehicle has
warmed up.
Some pixels in the display are
darker or brighter than others.This condition is an inherent characteristic of liquid
crystal displays.This is not a malfunction.
Some menu items cannot be
selected.Some menu items become unavailable while the
vehicle is driven.Park the vehicle in a safe location, and
then operate the navigation system.
Symptom Possible cause Possible solution
Names of roads and locations dif-
fer between Plan view and Bird-
view™.This is because the quantity of the displayed infor-
mation is reduced so that the screen does not
become too crowded. There is also a chance that
names of the roads or locations may be displayed
multiple times, and the names appearing on the
screen may be different because of a processing
procedure.This is not a malfunction.
The vehicle icon is not displayed in
the correct position.The vehicle was transported after the ignition switch
was turned off, for example, by a ferry or car trans-
porter.Drive the vehicle for a while on a road
where GPS can be received.
The position and direction of the vehicle may be
incorrect depending on the driving environments and
the levels of positioning accuracy of the navigation
system.This is not a malfunction. Drive the vehi-
cle for a while to automatically correct the
position and direction of the vehicle icon.
When the vehicle is travelling on a
new road, the vehicle icon is
located on another road nearby.Because the new road is not stored in the map data,
the system automatically places the vehicle ion on
the nearest road available. Updated road information will be included
in the next version of the map DVD-ROM.
The screen does not switch to the
night screen even after turning on
the headlights. The daytime screen was set the last time the head-
lights were turned on.Set the screen to the night screen mode
using when turning on the headlights.
The map does not scroll even
when the vehicle is moving.The current location map screen is not displayed. Push “MAP”.
The vehicle icon is not displayed. The current location map screen is not displayed. Push “MAP”.

BCM (BODY CONTROL MODULE)PFP:284B2
System DescriptionNKS003XH
BCM (Body Control Module) controls the operation of various electrical units installed on the vehicle.
BCM FUNCTION
BCM has combination switch reading function for reading the operation of combination switches (light, wiper,
washer, turn signal) in addition to a function for controlling the operation of various electrical components. Also
it has an interface function allowing it to receive signals from the combination meter, and send signals to ECM
using CAN communication.
COMBINATION SWITCH READING FUNCTION
Description
BCM reads combination switch (lighting switch, wiper switch) status, and controls various electrical com-
ponent according to the result.
BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1-5)
and five input terminals (INPUT 1-5).
Operation Description
BCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in
turn.
If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals
(INPUT 1-5) becomes active.
At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects volt-
age change, and BCM determines that switch is ON.

BCM (BODY CONTROL MODULE)
Revision: 2007 April2007 M35/M45
Operation Table of BCM and Combination Switches
BCM reads operation status of combination switch using combinations shown in table below.
NOTE:
Headlamp system has a dual switch.
Sample Operation:
When lighting switch 1ST position is turned ON, contact in combination switch turns ON. At this time if
OUTPUT 4 transistor is activated, BCM detects that voltage changes in INPUT 5.
When OUTPUT 4 transistor is ON, BCM detects that voltage changes in INPUT 5, and judges that lighting
switch 1ST position is ON. Then BCM sends tail lamp and clearance lamp request signal to IPDM E/R
using CAN communication.
When OUTPUT 4 transistor is activated again, BCM detects that voltage changes in INPUT 5, and recog-
nizes that lighting switch 1ST position is continuously ON.
NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electri-
cal loads are activated with time delay. But this time delay is so short that it cannot be detected by human
senses.

Operation Mode
Combination switch reading function has operation modes shown below.
1. Normal status
When BCM is not in sleep status, OUTPUT terminals (1-5) send out ON signal every 10 ms.
2. Sleep status
When BCM is in sleep status, transistors of OUTPUT 1 stop the output, and BCM enters low power
mode. Mean while OUTPUT 2-5 send out ON signal every 60 ms, and accept only input from lighting
switch (except turn signal switch) system.
CAN COMMUNICATION CONTROL
CAN communication allows a high rate of information transmission through the two communication lines (CAN
L line, CAN H line) connecting the various control units in the system. Each control unit transmits/receives
data but selectively reads required data only. For details of signals that are transmitted/received by BCM via
CAN communication, refer to LAN-50, "
CAN System Specification Chart" .
