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 will illuminate briefly or flash at key up:
• | 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
.
Average Fuel Economy (wU02)
The average fuel economy is a function of distance traveled divided
by fuel used since the parameter was last reset. When the average fuel economy
is displayed in the IPC, pressing the INFO RESET button on the DIC will
reset the average fuel economy parameter. On vehicles equipped
w/UY9, the average fuel economy parameter is only displayed on
the DIC.
The average fuel economy displays either miles or kilometers
as requested by briefly pressing the ENG/MET button on the driver information
center (DIC).
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 signal
circuit. |
• | The IPC detects a loss of class 2 communications with the
PCM. |
Fuel Range (w/U02)
The fuel range is the estimated distance that the vehicle can travel
under the current fuel economy and fuel level conditions. The fuel range parameter
cannot be reset by the driver. "LO" is displayed in
the fuel range display when the range is calculated to be less
than 64 km (40 miles). The fuel range displays
either miles or kilometers as requested by briefly pressing the
ENG/MET button on the driver information center (DIC).
Odometer
The IPC contains a season odometer and two trip odometers. 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 briefly pressing the ENG/MET button on the driver information
center (DIC). Pressing the RESET TRIP A/B button for greater than 2 seconds
will reset the trip odometer that is displayed.
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
signal circuit. |
• | The IPC receives a class 2 message indicating the park
position and the column park switch indicates a position other than park. |
• | 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 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 from the PCM in order to calculate the vehicle speed.
The speedometer defaults to 0 km/h (0 mph) if a
malfunction in the vehicle speed signal circuit exists. The
speedometer displays either miles or kilometers as requested
by briefly pressing the ENG/MET button on the DIC.
On vehicles equipped w/UY9 the speedometer display configuration can
be changed by using the DSPL MODE button. The speedometer can be configured
in one of the following formats:
• | Analog and digital displays |
Tachometer (w/UY9)
The IPC displays the engine speed based on information received from
the PCM. The PCM converts the data from the engine to 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.
