Another FICM voltage quesiton
I have a Scangauge and one of the things I monitor is the FICM voltage. Generally I'm at 47-48.5, except at start up in the morning where it will start at 36 and quickly move up to 45, 46, 47, 48. This is only with the first start of the morning.
Today I turned the key to the "on" position (did not turn the truck on), then I turned on the Scangauge and I saw that it starts out at about 35, but quickly (over about 5-8 seconds) goes up to 47-48. THEN I turned on the truck.
Does anyone see a problem here? That's not a trick question.
Would it make sense to practice this starting procedure?
In other words, is it less stress on the FICM if I wait the 5-10 seconds for the voltage to go up BEFORE starting the truck?
Does it spare the FICM any stress?
