seconds delay before the warning is displayed or removed.
Engine Coolant Temperature Warning (CHECK ENGINE TEMP)
This warning message is displayed when the engine coolant is overheating.
The message center indicator senses the voltage level on Circuit 39 (RD/WH) (C2008-8 to the message center indicator).
If that voltage is greater than approximately 2.7 volts, at a battery voltage of 13.5 volts there will be no warning. if it is less than approximately 2.7 volts,
at a battery voltage of 13.5 volts then the warning will be displayed.

This warning message is displayed when there is approximately 80 km (50 mile) or less left before the vehicle runs out of fuel.
Oil Level Warning (LOW OIL LEVEL)
This warning message is displayed when the engine oil level is low.
When the engine oil level is normal, the input to the message center indicator will be an open circuit.
When the engine oil level is low, the low oil level sensor will close, grounding the input to the message center indicator and the warning will be
displayed during the next ignition cycle of OFF to RUN. This low oil level sensor is only monitored when the ignition switch is OFF.
There is a delay of up to 12 minutes in this monitoring in order to allow the oil to drain back into the oil pan and reach the correct level.
Oil Life Warning (CHANGE OIL SOON or OIL CHANGE REQUIRED)
If the connection to the oil temperature sensor is open circuit or shorted, the message center display will read OIL TEMP SIGNAL ERROR instead of
displaying the PERCENTAGE OIL LIFE LEFT during system check sequence.
