< SYMPTOM DIAGNOSIS >
NORMAL OPERATING CONDITION
RELATED TO ROUTE CALCULATION AND VISUAL GUIDANCE
The vehicle icon is not displayed in
the correct position.The vehicle was transported after the ignition
switch was pressed off, for example, by a ferry
or car transporter.
Drive the vehicle for a while on a road where
GPS signals can be received.
The position and direction of the vehicle icon
may be incorrect depending on the driving en-
vironments and the levels of positioning accu-
racy of the navigation system. This is not a malfunction. Drive the vehicle for
a while to automatically correct the position
and direction of the vehicle icon.
When the vehicle is traveling 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 vehi-
cle icon on the nearest road available.
Updated road information will be included in
the next version of the map data.
The screen does not switch to the
night screen even after turning on
the headlights. The daytime screen was set the last time the
headlights were turned on.
Set the screen to the night screen mode using
when you turn on the headlights.
The map does not scroll even when
the vehicle is moving. The current location map screen is not dis-
played.
Press “MAP”.
The vehicle icon is not displayed. The current location map screen is not dis-
played.
Press “MAP”.
The location of the vehicle icon is
misaligned from the actual position. When using tire chains or replacing the tires,
speed calculations based on the speed sensor
may be incorrect. Drive the vehicle for a while [at approximately
30 km/h (19 MPH) for about 30 minutes] to
automatically correct the vehicle icon posi-
tion.
If this does not correct the vehicle icon posi-
tion, contact an INFINITI dealer.
The map data has a mistake or is incomplete
(the vehicle icon position is always misaligned
in the same area). Updated road information will be included in
the next version of the map data.
Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
Waypoints are not included in
the auto reroute calculation. Waypoints that you have already passed are not included in
the auto reroute calculation. If you want to go to that waypoint
again, you need to edit the route.
Route information is not dis-
played. Route calculation has not yet been performed.
Set the destination and perform route
calculation.
You are not driving on the suggested route. Drive on the suggested route.
Route guidance is set to off. Turn on route guidance.
Route information is not provided for certain types of roads
(roads displayed in gray). This is not a malfunction.
The auto reroute calculation (or
detour calculation) suggests
the same route as the one pre-
viously suggested. Route calculations took priority conditions into consider-
ation, but the same route was calculated.
This is not a malfunction.
A waypoint cannot be added. Five waypoints are already set on the route, including ones
that you have already passed. A maximum of 5 waypoints can be set
on the route. If you want to go to 6 or
more waypoints, perform route calcu-
lations multiple times as necessary.
The suggested route is not dis-
played. Roads near the destination cannot be calculated.
Reset the destination to a main or or-
dinary road, and recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far away. Divide your trip by selecting one or two
intermediate destinations, and per-
form route calculations multiple times.
There are time restricted roads (by the day of the week, by
time) near the current vehicle location or destination. Set [Use Time Restricted Roads] to
off.

BODY CONTROL SYSTEM
BODY CONTROL SYSTEM : System DescriptionINFOID:0000000006274789
OUTLINE
 BCM (Body Control Module) controls the various electrical components. It inputs the information required to
the control from CAN communication and the signal received from each switch and sensor.
 BCM has combination switch reading function for reading the operation status of combination switches (light,
turn signal, wiper and washer) in addition to a function fo r controlling the operation of various electrical com-
ponents. It also has the signal transmission function as the passed point of signal and the power saving con-
trol function that reduces the power c onsumption with the ignition switch OFF.
 BCM is equipped with the diagnosis function that perfo rms the diagnosis with CONSULT-III and various set-
tings.

 BCM reads the status of the combination switch (light, turn signal, wiper and washer) and recognizes the
status of each switch.
 BCM has a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5). It reads a
maximum of 20 switch status.

COMBINATION SWITCH READING FUNCTION
Description
 BCM reads the status of the combination switch at 10 ms interval normally.NOTE:
BCM reads the status of the combination switch at 60 ms interval when BCM is controlled at low power con-
sumption control mode.
 BCM operates as follows and judges the status of the combination switch.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 1 → 2 → 3 → 4 → 5, and outputs
voltage waveform.
- The voltage waveform of OUTPUT corresponding to the formed circuit is input into the interface on INPUT
side if any (1 or more) switches are ON.
- It reads this change of the voltage as the status signal of the combination switch.
Operation Example
In the following operation example, the combination of t he status signals of the combination switch is replaced
as follows: INPUT 1 - 5 to “1 - 5” and OUTPUT 1 - 5 to “A - E”.
Example 1: When a switch (TAIL LAMP switch) is turned ON
OUTPUT 3 WIP VOLUME 1 RR WASHER — HEADLAMP 2 HI BEAM
OUTPUT 4 RR WIPER INT WIP VOLUME 3 AUTO LIGHT — TAIL LAMP
OUTPUT 5 WIP VOLUME 2 RR WIPER ON RR FOG FR FOG — System INPUT 1 INPUT 2 INPUT 3 INPUT 4 INPUT 5
