Displays Test
Certain instrument panel cluster (IPC) features are tested when the
ignition is turned on in order to verify the features are working properly.
The following illuminate briefly or flash at key up:
| • | The air bag indicator flashes 7 times. |
| • | The engine coolant indicator |
| • | The engine oil pressure indicator |
| • | The fasten belts indicator |
| • | The service engine soon indicator (MIL) |
Indicators and Warning Messages
Refer to
Indicator/Warning Message Description and Operation
.
Engine Coolant Temperature Gage
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 gage defaults
to C 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. |
Fuel Gage
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 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 IPC contains a season odometer and a trip odometer. Press the RESET
TRIP A/B button for greater than 2 seconds 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 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 ENG/MET button on the driver information center (DIC). The
associated indicator (km or MI) illuminates.
PRNDL 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 PRNDL 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 IPC displays the vehicle speed based on the information received
from the power control module (PCM). The PCM converts the data received from
the vehicle speed sensor into a 4000 pulses/mile signal. The IPC uses the
vehicle speed signal circuit from the PCM in order to calculate the vehicle
speed. The speedometer defaults to 0 MPH (0 km/h) if
a malfunction in the vehicle speed signal circuit exists.
The speedometer displays either miles or kilometers as requested by
the activation of the ENG/MET button on the driver information center
(DIC). The associated indicator (km/h or MPH) illuminates. The speedometer
display configuration can be changed as requested by the activation of
the DSPL MODE button on the driver information center (DIC) switch. The
speedometer can be configured in the following formats:
| • | Analog and digital displays |
Tachometer
The IPC displays the engine speed based on information received from
the PCM. The PCM converts the data received from the engine into a 2 pulses
per engine revolution signal. The IPC uses the engine speed signal circuit
from the PCM in order to calculate the engine speed. The tachometer defaults
to 0 RPM if a malfunction in the engine speed signal circuit exists.
Voltmeter
The IPC displays the system voltage as detected at the ignition 1
input of the IPC.
