Driver/Vehicle Information Display: Initial Inspection and Diagnostic Overview
Principles of Operation
PRINCIPLES OF OPERATION
The message center is a vacuum fluorescent display, which is part of the instrument cluster. The message center electronic functions use both hardwired
and controller area network (CAN) circuits to transmit and receive information. As a technician it is very important to understand:
-
where the input (command) originates from.
-
all the information (messages) necessary in order for a feature to operate.
-
which module(s) receive(s) the input or command message.
-
does the module which received the input (message) control the output of the feature, or does it output a message over the CAN circuits to another
module.
-
which module controls the output of the feature.
The message center provides the following features:
-
information displays
-
setup displays
-
warning messages
-
system check messages
The message center information can be selected through a set of 3 buttons:
-
SET
-

The message center buttons are located on the steering wheel assembly, behind the steering wheel audio control buttons.
