INDICATORS AND DRIVER INFORMATION CENTER (DIC)

Engine Coolant Temperature
Gauge
The IPC displays the engine coolant temperature as
determined by the PCM. The IPC receives a class 2
message from the PCM indicating the engine coolant
temperature. The engine coolant temperature gauge
defaults to 100
_
F (40
_
C) or below if:
S
The PCM detects a malfunction in the engine
coolant temperature sensor circuit.
S
The IPC detects a loss of class 2 communications
with the PCM.
Engine Oil Pressure Gauge
The IPC displays the engine oil pressure as determined
by the PCM. The IPC receives a class 2 message from
the PCM indicating the engine oil pressure. The engine
oil pressure gauge defaults to 0 psi (0 kPa) or below if:
S
The PCM detects a malfunction in the engine oil
pressure sensor circuit.
S
The IPC detects a loss of class 2 communications
with the PCM.
Fuel Gauge
The IPC displays the fuel level as determined by the
PCM. The IPC receives a class 2 message from the
PCM indicating the fuel level percent. The fuel gauge
defaults to empty if:
S
The PCM detects a malfunction in the fuel level
sensor circuit.
S
The IPC detects a loss of class 2 communications
with the PCM.
When the fuel level is less than a pre-determined value,
the IPC illuminates the low fuel indicator.
Odometer
The base IPC contains a season odometer and a trip
odometer. The uplevel IPC contains a season
odometer and two trip odometers. 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 IPC calculates the mileage based on the vehicle
speed signal circuit from the PCM. The odometer will
display ’error’ if an internal IPC memory failure is
detected. The odometer displays either miles or
kilometers as requested by the activation of the
Personalization button on the steering wheel controls.
PRND321 Display
The IPC displays the selected gear position as
determined by the PCM. The IPC receives a class 2
message from the PCM indicating the gear position.
The PRND321 display blinks if:
S
The PCM detects a malfunction in the transmission
range switch circuit.
S
The IPC detects a loss of class 2 communications
with the PCM.
Speedometer
The IPC displays the vehicle speed based on the
information from the PCM. The PCM converts the data
from the vehicle speed sensor to a 4000 pulses/mile
signal. The IPC uses the vehicle speed signal circuit
(4000 pulses/mile) from the PCM in order to calculate
the vehicle speed. If the IPC detects a malfunction in
the vehicle speed signal circuit, the IPC uses the class 2
message from the PCM indicating the vehicle speed.
Tachometer
The IPC displays the engine speed based on the
information from the PCM. The PCM converts the data
from the engine speed sensor to a 2 pulses/engine
revolution signal. The IPC uses the engine speed signal
circuit (2 pulses/engine revolution) from the PCM in
order to calculate the engine speed. If the IPC detects a
malfunction in the engine speed signal circuit, the IPC
uses the class 2 message from the PCM indicating the
engine speed.
Voltmeter
The IPC displays the vehicle voltage based on the
information from the BCM. The IPC uses class 2 serial
data information from the BCM to provide a voltage
level indication on the voltmeter.
