Explorer 2WD V6-245 4.0L SOHC VIN E EFI (1997)
Temperature Switch (Warning Indicator): Description and Operation
This warning message is displayed when the engine coolant is overheating.
The message center indicator senses the voltage level on Circuit 39 (R/W) (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.
The message center indicator filters this input; therefore there will be a few seconds delay before the warning is displayed or removed.
