SECTION 413-01: Instrumentation, Message Center, and Warning Chimes
DIAGNOSIS AND TESTING
Instrumentation, Message Center and Warning Chimes
Refer to Wiring Diagrams Cell 60 for schematic and connector information.

Special Tool(s)

73III Automotive Meter
105-R0057 or equivalent
Worldwide Diagnostic System (WDS)
Vehicle Communication Module (VCM) with appropriate adapters, or
equivalent diagnostic tool
Flex Probe Kit
105-R025C or equivalent

Principles of Operation

The instrument cluster receives information through hardwired circuitry and over the controller area network (CAN) to control the gauges, indicators, message center and warning chimes.
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 communication network circuits to another module.
which module controls the output of the feature.
Instrument cluster
The instrument cluster contains an analog speedometer, tachometer, fuel gauge, engine coolant temperature gauge, voltage gauge (if equipped), and a oil pressure gauge (if equipped).
The instrument cluster receives the information over the controller area network (CAN) circuits.

Instrument Cluster Configuration

When installing a new instrument cluster, it is necessary to upload the module configuration information to the diagnostic tool. Following installation of the instrument cluster, download the
module configuration information from the diagnostic tool into the new instrument cluster. For additional information, refer to
The following items are configurable:
Speedometer calibration
brake system
door ajar
shift indicator lamp
daytime running lamps (DRL)
door ajar warning chime

Instrument Cluster Prove-Out

The instrument cluster carries out a display prove-out to verify that the warning/indicator lamps and monitored systems are operating correctly. When the ignition switch is turned to the
ON position, the charging system warning indicator, the low oil pressure warning indicator, and the malfunction indicator lamp (MIL) illuminate until the engine is started and operating
normally. The safety belt warning indicator proves out for 65 seconds or until the safety belt is fastened.
Each time the ignition switch is turned from the OFF to the ON positions, the following instrument cluster warning indicators prove out:
anti-lock brake (ABS) warning indicator (3 seconds)
air bag warning indicator (6 seconds)
Brake Warning Indicator (3 seconds)
fail safe cooling warning indicator (3 seconds)
low fuel warning indicator (3 seconds)
traction control indicator (3 seconds)
Anti-Theft Indicator (3 seconds)
check fuel cap warning indicator (3 seconds)
