Instrument Cluster Description and
Operation
Displays Test
Certain instrument panel cluster (IPC) features are
tested when the ignition is turned on in order to verify
that the features are working properly. The following
indicators illuminate briefly at key up:
• ABS
• Air bag—flashes 7 times
• Brake system
• Charging system
• Change Engine Oil
• DRL
• Engine Coolant Temperature
• High beam indicator
• Liftgate Ajar
• Low Fuel
• Low oil pressure indicator
• Low Traction indicator
• Malfunction indicator lamp (MIL)—Check engine
• Reduced Engine Power indicator
• Security indicator
• Service Vehicle Soon indicator
• Stability System Disabled
• Tire Pressure Monitor
• Traction Off
Indicators and Warning Messages
Refer to "Indicator/Warning Message Description and
Operation".
Engine Coolant Temperature Gage
The powertrain control module (PCM) sends coolant
temperature as determined by the coolant temperature
sensor to the body control module (BCM) via controller
area network (CAN) serial data. The instrument panel
cluster (IPC) displays the engine coolant temperature
with the gage when the BCM sends a class 2 message
to the IPC indicating coolant temperature percentage.
The engine coolant temperature gage defaults to cold
(0°) or below if:
• The PCM detects a malfunction in the engine coolant
temperature sensor circuit.
• The IPC detects a loss of class 2 communications
with the BCM.
• The BCM detects a loss of CAN communications with
the PCM.
General Description
Fuel Gage
The PCM sends fuel level percent to the BCM via CAN
serial data. The IPC displays the fuel level as
determined by the BCM. The fuel gage defaults to E
(empty) if:
• The PCM detects a malfunction in the fuel level
sensor circuit.
• The IPC detects a loss of class 2 communications
with the BCM.
• The BCM detects a loss of CAN communications with
the PCM.
When the fuel level is less than a pre-determined value,
the Low Fuel indicator message illuminates.
Odometer
The odometer shows how far the vehicle has been
driven, in either miles (domestic) or kilometers (export).
The odometer is shown on display when any of the
following occur:
• Ignition is in ACC
• Ignition is in RUN, with no messages on
• The trip reset stem is pressed with the ignition OFF
Odometer readings are displayed in the IPC based on a
class 2 message from the BCM. The PCM calculates the
distance traveled from the vehicle speed sensor (VSS)
input. The BCM receives a CAN serial data message
from the PCM and stores the current mileage.
The IPC stores the last valid odometer reading from the
BCM in non-volatile memory. When a new valid
odometer reading is received from the BCM, the IPC will
update the display and store the new reading.
The IPC also receives class 2 messages from the BCM
regarding VIN and Vehicle content information. Valid
information is stored in non-volatile memory at the first
key-up with a new IPC. If the VIN or option content do
not match the stored information, the odometer will
display ERROR.
