How many CAN bus modules?

How many CAN bus modules do these trucks 2023+ have? Where are they located?

I'm not trying to do anything, just curious to know more about our trucks.

There are 20+ modules in newer Ford trucks. Almost everything is controlled over a network (high speed, medium speed or LIN). Dig into the forum stickies for Forscan .You must have a good scan tool to do almost any work on theses vehicles besides changing oil and air filter. Forscan is free and Autel makes good products but you need to spend about $400 for a full service tool.

Ok that's more modules than I thought.

What full service tool are people using these days?

Forscan is the go-to for PC (not Apple) users and Ford only use. Requires an adapter ($50 approx). Owners of other manufacturers can use Autel or others. Autel MK808 isn't repair shop quality ($2000+) but allows for garage mechanic level diagnosis and service functions.

All scan tools have a learning curve and expect to spend hours watching YouTube to learn how to use them. Forscan is the most "difficult" to learn because it is not as intuitive as commercial tools, but it is as powerful as a $2k tool.

If you can get a hold of a service and wiring manual, there’s a lot of good info.

In excess of 25k pages, it’s hard to digest it all.

This is not as good as having the real manual, but still lots of information.
