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 indicators illuminate briefly at key up unless otherwise
noted:
• | Air bag (flashes 7 times) |
• | Low engine coolant level |
• | Malfunction indicator lamp (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 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. |
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. |
When the fuel level is less than 14% (74ohms), the low fuel indicator
illuminates.
Odometer
The IPC contains a season odometer and a trip odometer. Momentarily
press the TRIP ODO switch 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 class 2 vehicle speed
message from the PCM. The odometer will display 'error' if an internal
IPC memory failure is detected.
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 from the
PCM. The IPC receives a class 2 message from the PCM indicating
the vehicle speed. The speedometer defaults to 0 kph (0 mph)
if:
• | The PCM detects a malfunction in the vehicle speed sensor circuit. |
• | The IPC detects a loss of class 2 communications with the
PCM. |
Tachometer
The IPC displays the engine speed as determined by the PCM. The IPC
receives a class 2 message from the PCM indicating the engine speed.
The tachometer will default to 0 rpm if:
• | The PCM detects a malfunction in the engine speed sensor circuit. |
• | The IPC detects a loss of class 2 communications with the
PCM. |
