Indicators and Warning Messages

Refer to Indicator/Warning Message Description and Operation.

Engine Coolant Temperature Gage

The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the
powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating
the engine coolant temperature. The engine coolant temperature gage defaults to 100°F (40°C) 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 PCM.

Engine Oil Pressure Gage

The instrument panel cluster (IPC) displays the engine oil pressure as determined by the
powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating
the engine oil pressure. The engine oil pressure gage defaults to 0 psi (0 kPa) or below if:

The PCM detects a malfunction in the engine oil pressure (EOP) sensor circuit.

The IPC detects a loss of class 2 communications with the PCM.

Fuel Gage

The instrument panel cluster (IPC) displays the fuel level as determined by the powertrain control
module (PCM). The IPC receives a class 2 message from the PCM indicating the fuel level
percent. The fuel gage defaults to empty if:

The PCM detects a malfunction in the fuel level sensor circuit.

The IPC detects a loss of class 2 communications with the PCM.

Odometer

The base instrument panel cluster (IPC) contains a season odometer and a trip odometer.
Momentarily press the trip/reset switch on the IPC in order to toggle between the season
odometer and the trip odometer. Press the trip/reset switch for greater than 2 seconds, while the
trip odometer is displayed, in order to reset the trip odometer.

The body control module (BCM) calculates the mileage based on the vehicle speed signal circuit
from the powertrain control module (PCM). The BCM then sends a class 2 message to the IPC
indicating the value of the odometer. The odometer will display 'error' if an internal BCM
memory failure is detected.

PRND321 Display

The instrument panel cluster (IPC) displays the selected gear position as determined by the
powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating
the gear position. The PRND321 display blanks if:

The PCM detects a malfunction in the transmission range switch circuit.

The IPC detects a loss of class 2 communications with the PCM.

Speedometer

The instrument panel cluster (IPC) displays the vehicle speed based on the information from the
powertrain control module (PCM). The PCM converts the data from the vehicle speed sensor to a
4000 pulses/mile signal. The IPC receives a class 2 message from the PCM indicating the vehicle
speed.

Tachometer

The instrument panel cluster (IPC) displays the engine speed based on the information from the
powertrain control module (PCM). The PCM converts the data from the engine speed sensor to a
2 pulses/engine revolution signal. The IPC receives a class 2 message from the PCM indicating
the engine speed.

Voltmeter

The instrument panel cluster (IPC) displays the vehicle voltage based on the information from the
body control module (BCM). The IPC uses class 2 serial data information from the BCM to
provide a voltage level indication on the voltmeter.
