Hello Guys.
I was told i need a new computer for the 6.0, kinda confused the computer is the ecm or pcm the ficm is just for the injectors.the one that is on the fender well driver side that is the computer rite.

PCM= Power Control Module
ECM= Engine Control Module
FICM= Fuel Injector Control Module
TCM= Transmission Control Module
They are all computers and are in different places.

witch one would control the air conditioner and the throttle positioning censor?

[WarChild]

TPS would be monitored by the ECM your foot controls it....lol none control the AC. Maybe the vacuum pump but not the AC itself.

I have a spare PCM if you need one cheap. You might need to have it programmed with your VIN depending on your year.

[bismic]

The PCM consists of the ECM and TCM (and in some model years the GEM)

[themetalman]

so witch one would control the fan clutch?

[bismic]

I don't believe you can buy separate components (boards) for the PCM but it would be the Engine Control Module that controls the fan (not the Transmision Control Module)

[themetalman]

I have replaced two fan clutch and still can't get then to work,they will just not engage.do you have to reprogram the ecm, to get the clutch fan to operate when it should.
