Basic Operation
Vehicle Mark
The other party’s voice cannot be heard by hands-free phone. When the radio wave condition is not ideal or ambient sound is too
loud, it may be difficult to hear the other person’s voice during a
call.
Poor sound quality. Do not place the cellular phone in an area surrounded by metal or
far away from the in-vehicle phone module to prevent tone quality
degradation and wireless connection disruption.
Symptom
Cause and Counter measure
SymptomCause Remedy
No image is shown. Display brightness adjustment is set fully to DARK
side. Adjust the display brightness.
No guide sound is heard.
Audio guide volume is too low or
too high. Volume control is set to OFF, MIN or MAX. Adjust the audio guide volume.
Audio guidance is not available while the vehicle is
driving on a dark pink route.
System is not malfunctioning.
Screen is too dark.
Motion of the image is too slow. Temperature inside the vehicle is low.
Wait until the temperature inside the vehicle
reaches the proper temperature.
Small black or bright spots appear
on the screen. Symptom peculiar to a liquid crystal display (dis-
play unit). System is not malfunction.
Symptom
Cause Remedy
Map screen and BIRDVIEW™
Name of the place vary with the
screen. Some thinning of the character data is done to pre-
vent the display becoming to complex. In some
cases and in some locations, the display contents
may differ.
The same place name, street name, etc. may not
be displayed every time on account of the data
processing. System is not malfunctioning.
Vehicle mark is not positioned cor-
rectly. Vehicle is transferred by ferry or by towing after its
ignition switch is turned to OFF. Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.
Screen will not switch to nighttime
mode after the lighting switch is
turned ON. The daytime screen is selected by the “SWITCH
SCREENS” when the last time the screen dim-
ming setting is done.
Switching between daytime/nighttime screen may
be inhibited by the automatic illumination adjust-
ment function. Perform screen dimming and select the
nighttime screen by “SWITCH SCREENS”.
Map screen will not scroll in accor-
dance with the vehicle travel. Current location is not displayed.
Press “MAP” button to display the current lo-
cation.
Vehicle mark will not be shown. Current location is not displayed. Press “MAP” button to display the current lo-
cation.
Accuracy indicator (GPS satellite
mark) on the map screen stays
gray. GPS satellite signal is intercepted because the ve-
hicle is in or behind a building.
Move the vehicle out to an open space.
GPS satellite signal cannot be received because
an obstacle is placed on top of the instrument pan-
el. Do not place anything on top of the meter dis-
play (instrument panel).
GPS satellites are not visible from current location. Wait until GPS satellites are visible by mov- ing the vehicle.

< SYSTEM DESCRIPTION >[WITH INTELLIGENT KEY SYSTEM]
SYSTEM
• BCM switches the status (control mode) by itself wit
h the power saving control function. It performs the sleep
request to each unit (IPDM E/R and combination mete r) that operates with the ignition switch OFF.
Normal mode (wake-up)- CAN communication is normally performed with other units
- Each control with BCM is operating properly
CAN communication sleep mode (CAN sleep)- CAN transmission is stopped
- Control with BCM only is operating
Low power consumption mode (BCM sleep)- Low power consumption control is active
- CAN transmission is stopped
LOW POWER CONSUMPTION CONTROL WITH BCM
BCM reduces the power consumption with the following operation in the low power consumption mode.
• The reading interval of each switch changes from 10 ms interval to 60 ms interval.
Sleep mode activation
• BCM receives the sleep-ready signal (ready) from IPDM E/R and combination meter via CAN communica-
tion.
• BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful- filled.
• Each unit stops the transmission of CAN communication with the sleep wakeup signal. BCM is in CAN com- munication sleep mode.
• BCM is in the low power consumption mode and perform s the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
Sleep condition
Wake-up operation
• BCM transmits the sleep wake up signal (wake up) to each unit when any of the CAN wake-up conditions are fulfilled. It changes from the low power consumption mode or the CAN communication sleep mode to the
normal mode.
• Each unit starts the transmission of CAN communication with the sleep wake up signal. In addition, the com- bination meter transmits the wake up signal to BCM via CAN communication to report the CAN communica-
tion start.
