Indicators and Warning Messages
Refer to Indicator/Warning Message Description and Operation, Data Link
Communications Description and Operation , and Body Control System Description and
Operation .
Engine Coolant Temperature Gage
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the
engine control module (ECM). The IPC receives a GMLAN message from the ECM indicating
the engine coolant temperature. The engine coolant temperature gage defaults to 60°C (140°F) or
below if:
The ECM detects a malfunction in the engine coolant temperature sensor circuit.
The IPC detects a loss of GMLAN communications with the ECM.
The body control module (BCM) detects a loss of GMLAN communications with the ECM.
Fuel Gage
The instrument panel cluster (IPC) displays the fuel level as determined by the ECM. The IPC
receives a GMLAN message from the ECM indicating the fuel level percent. The fuel gage
defaults to empty if:
The ECM detects a malfunction in the fuel level sensor circuit.
The IPC detects a loss of GMLAN communications with the ECM
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates in the
IPC.
Odometer
The vehicle odometer is calculated and stored electronically in the instrument panel cluster (IPC).
The IPC contains a season odometer and trip odometer A or B. Momentarily press the DIC
trip/fuel button on the IPC in order to toggle between the season odometer and the trip odometer.
Press the DIC set/reset button for greater than 0.25 seconds, while the trip odometer is displayed,
in order to reset the trip odometer. The IPC displays the vehicle mileage and trip mileage as
determined by the IPC. The IPC calculates the mileage based on the GMLAN vehicle speed
information from the ECM. The odometer will display 'error' if an internal IPC memory failure is
detected. The odometer displays either miles or kilometers and can be set through the
personalization programming menu in the DIC.

The IPC displays the selected gear position as determined by the ECM. The IPC receives a
GMLAN message from the ECM indicating the gear position. The PRNDL display blanks if:
The ECM detects a malfunction in the transmission range switch circuit.
The IPC detects a loss of GMLAN communications with the ECM.
Speedometer
The IPC displays the vehicle speed as determined by the ECM. The IPC calculates the mileage
based on the GMLAN vehicle speed information from the ECM. The speedometer defaults to 0
km/h (0 mph) if the IPC detects a loss of GMLAN communications with the ECM.
Tachometer
The IPC displays the engine speed as determined by the ECM. The IPC receives a GMLAN
message from the ECM indicating the engine speed. The tachometer will default to 0 RPM if:
The ECM detects a malfunction in the engine speed sensor circuit.
The IPC detects a loss of GMLAN communications with the ECM.
Battery Gage
The instrument panel cluster (IPC) displays the voltage as determined by the regulated voltage
control (RVC). The IPC receives a GMLAN message from the BCM indicating the battery
voltage. When the engine is ON, the gage should be between 10-16 volts. The gage will default to
0 volts if the IPC detects a loss of communication with the BCM.
