The monitor will not run unless:
- mil is off.
- Fuel level is approximately 1/2 to 3/4.
- Altitude is 7800 feet (2400 m) or less.*
- Engine coolant temperature (ect) is between 40°f and 95°f (4.4 °C and 35 °C).

Hint
:
examples:
- scenario 1
ect = 75°f (24 °C)
iat = 60°f (16 °C)
difference between ect and iat is 15°f (8 °C).The monitor will not run because difference between ect and iat is greater than 13°f (7 °C).
- Scenario 2

iat = 68°f (20 °C)
difference between ect and iat is 2°f (1 °C).The monitor will run because difference between ect and iat is less than 13°f (7 °C).
