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:
• | Air bag (flashes 7 times) |
• | Hot coolant temperature |
• | Low engine oil pressure |
• | Service engine soon (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 IPC illuminates the hot coolant
temperature indicator when the coolant temperature reaches 124°C
(255°F).
Fuel Gage
The IPC monitors the fuel level signal circuit, and when the fuel tank
level is full, the sensor resistance is high and the IPC senses a high signal
voltage. When the fuel tank level is empty , the sensor resistance is low
and the IPC senses a low signal voltage. When the fuel tank level is less
than 16 percent, the low fuel indicator illuminates.
Odometer
The IPC contains a season odometer and a trip odometer. Momentarily
press the DIC 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 Eng/Met button
on the driver information center (DIC). The associated indicator
(km or MPH) illuminates.
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 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.
Tachometer
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.
