Airbag plugs into clock spring assembly, clock spring assembly connects to body harness, body harness connects to the ACM. The book may be calling the Airbag Control Module the "Data Link Collector", but I'm not certain. That wording doesn't ring a bell to me, but it has been nearly ten years since since I was a Ford Intern Tech.Quote:

PCM is the same as PCU, ECM, ECU. Powertrain Control Module (Unit) Engine Control Module (Unit). Depends on the year of manufacture. Ford changes their names for the same thing overtime.Quote:

Now you know how I feel!Quote:

Well, in that case, why don't they simply use 2 C250 instrument clusters instead of a C250 and a C251?Quote:

Just pulling that out from where the sun don't shine as I really do not know. I don't even know what C250 and C251 are.Quote:

Otherwise they appear functionally identical. I figure it must be for the same reason that I had to have half of the top of the engine removed to replace a faulty tranny fluid cooler door sensor so that the damn check engine light would go off and I could get my new inspection sticker.
Are you getting C250 and C251 from a schematic or diagram? If so, that would be the code for the connection. C250 would be Connection #250 and C251 would be Connection #251. No two connections would ever have the same number.Quote:

After experiencing a heat sensor problem on my '99 F 150, (under manifold $1300 bucks), and a lengthy quest to find the fuse for the trailer running lights, (shorted plug) on the 2008 F 250.....I have discovered that service manuals, and owner manuals are completely useless.
Dealer techs are a bit better but do expect you to pay form their lack of knowledge, (reference the 2 visit, not finding the problem the first time, so having to pay for the second visit).
Having been around awhile, and built several race cars from basically scratch, HVAC service tech for 10 years, so don't feel I am totally stupid, but I have concluded.....we need not worry about EMP and such......our gadgets will be out down fall on any thing newer the maybe 1969? or so.
If all else fails, park in field and use for chicken coop, they make new ones evert day.
Good luck on your quest on the Jeep, must have been interesting to get to that stage.
It was very interesting, my ramps slipped just as the front tires were coming off the trailer. Grand Cherokee bumpers are not ment to support the weight of the jeep, so now it laying next to the jeep.Quote:
