Multi Display
A multi display is available as an option for MID TECHNICAL and MID ELEG\

models.
Navigation and trip information can be displayed on the multi display.
Navigation System

Through the use of the GPS (Global Positioning System) and map data in a DVD \
(Digital
Versatile Disc), the navigation system analyzes the position of the vehi\
cle and indicates that
position on the map that is displayed on this screen.

The navigation system employs a voice recognition function with a voice \
recognition
microphone installed in the overhead console. The voice recognition function can b\
e turned
on and off using the steering switch on the steering wheel.

The navigation system is operated using a remote controller.
Trip Information
Average fuel consumption after refueling, momentary fuel consumption, ave\
rage vehicle speed,
driving distance after engine start, and driving range can be displayed.\

SYMPTOM CONFIRMATION AND DIAGNOSTIC TROUBLE CODE
HINT:

The diagnostic system in AVENSIS has various functions. The first function is the Diagnostic Trouble
Code (DTC) Check, in which a malfunction in the signal circuits to the ECU is stored in code form in
the ECU memory. Another function is the Input Signal Check, which checks if the signals from various
switches are sent to the ECU correctly. By using these check functions, it is possible to quickly narrow
down potential problem areas and troubleshooting can be performed effectively. The diagnostic func-
tions are incorporated in the following systems in the AVENSIS.

In the DTC check, it is very important to determine whether the problem indicated by the DTC is still
occurring or has occurred in the past but returned to normal at present. In addit\
ion during the problem
symptom check, it a check must be made on whether the malfunction indicated by \
the DTC is directly
related to the problem symptom or not. For this reason, the DTC should be checked before and after
symptom confirmation to determine the current conditions. If this is not done, \
it may, depending on the
case, result in unnecessary troubleshooting for systems that are operati\
ng normally. This would make
more difficult to detect the problem area or to try to repair irrelevant areas. \
Therefore, always follow
the procedures in the correct order and perform the DTC check.

A flow chart showing how to proceed with troubleshooting using the diagnostic trouble\
code (DTC)
check is shown the this page. This flow chart shows how to utilize the DTC check effectively. Then,
by carefully checking the results, this chart indicates how to proceed either to the DTC troubleshooting
or to the troubleshooting of the problem symptoms table.
