Subject: Body Motion Control Computer Problem on 1997 Plymouth Van

My question is simple. What does it do besides interface with the cruise
control?

Your right it is an exact repeat of what you made earlier and Im going to
repeat what I said again. "what are you talking about"
Why don't you explain what is wrong with you vehicle and maybe someone will
give you an answer that could help you!! There is no such thing as a body
motion control computer.
Since the cruise control is not controlled by the Body control Module not
only are you confused but so is the person that is talking to you.

No, PCM is powertrain Control Module. That is the computer that controls
engine and emissions functions. The TCM is Transmission Control Module,
which is the computer that controls the Transmission. Learn something before
you post. Or better yet post a relevant question to which you would want an
answer. Oh, and if your BCM is in need of a replacement, why didn't you just
purchase a used one at a scrap yard for $50. and try it.

OK, fair enough. Here's the deal. My wife's van has had the cruise control
malfunction. It just cuts out pretty much randomly. She took it to the
Plymouth dealer, and they said the *body motion computer* (BMC) showed a
problem when they examined it with their diagnostic computer, and that it
would be a good idea to have it replaced. $800 later with a refurbished unit
it hadn't solved the problem. They examined the problem again and this time
they said it was the servo, so for about $100 it was replaced. That was
Monday. She hasn't had an opportunity to drive it long enough for failure.
Tomorrow she will be going on a long trip of 100 miles, and typically that's
where it's used. So far $900 paid out and no results.

I went to our library yesterday, and got onto a site called
arrc.epnet.com/autoapp/... There's probably a general name for the site, but
I don't know it. I looked at the data for a 1997 van, and found no mention
of the device. I did find a one page description of the cruise control with
a troubleshooting table. For my purposes, that's sufficient and really what
I was after; however, if you have an opinion, then please offer it.

Body motion module, body motion computer, body moton controller... Whatever
the proper name is fine. When we took it to a non-authorized dealer, they
couldn't peek into the innards of the device, since their diagnostic
computer wasn't equipped to handle the device. It's a computer.

Ok Dr. Watson I presume? First of all the BCM was replaced for absolutely no
reason at all. The cruise control is in no way connected to the BCM (Body
Control Module) get you money back on that!!!
Second, If the person that was diagnosing your problem had a good scan tool
or even new how to use one all they needed to do was go into the cruise
control monitor section of the tool. It would have showed the last cut off,
meaning what caused the cruise control to shut down. There are several
things that could cause the problem and it sounds as if they are going to
start tossing parts at it until you let them find it at your expense. The
brake switch, vacuum hose, cruise switches, the servo, the PCM, wiring, the
servo itself and the clock spring.......which leads me to ask this. Does the
horn work when you loose the cruise control? Is the air bag lite ever on?
There was a recall on the clock spring for this year vehicle which could
cause the cruise control to act up.

Thanks. That's very helpful. Ah, my wife will be absolutely delighted to
hear this. Yes, she now agrees that it's the PCM and not the BCM. She thinks
she got shafted. Of course, it will be unlikely that we can get our money
back. We had to exchange it for a refurb, and I don't think that's going to
fly with the dealer. Air bag light hasn't been on, and appears to work
normally. She knew about the spring. I'll be going to the dealer with her
tomorrow. Definitely going to ask about the scan tool. If I think there's a
chance we've been screwed, then I think I can get a pretty persuasive
consumer advocate to help.

I had a lesson recently on a non-car item that the dealer would be well
advised to use as a strategy. It boils down to this. Check the least costly
and least labor intense items first, then look for the more complicated
stuff. I spent 12 hours correcting a piece of equipment that could have been
narrowed to one or two hours if I had followed that advice. I guess the
benefit of the 12 hours is they equipment got a complete maintenance job by
me. Still, I would have settled for less effort.

Whoops. Strike my remark about the PCM/BCM. The BCM does exit and is what
got replaced. B and P are just too close in sound. She was talking to me
while I was responding and misheard her remark.

I think we now have enough info to ask for our money back. My wife,
cleverly, decided to take it up with our regular mechanic. He owns a highly
respected small shop. She presented the evidence to the owner, and he said,
"Get your money back." We now have a plan to do just that.

Well all you have to do is ask the person to show you where in the flow
chart (diagnostic procedure) does it say anything about the BCM related to
the cruise control, or ask for a wiring schematic that ties the cruise
control with the BCM and you got your money back.

Problem solved. The dealer told us they installed the wrong computer. Should
have been PCM and not BCM. The price difference is about the same as the
extra servo, so they gave us the two parts and remaining labor free. So far
it hasn't failed, but my wife will give it a test this weekend. She says it
behaves more like she believes it should. Forgot exactly what, but it had to
do with being in cruise control when she turned off the engine, and then
turned it on. The cruise control was still where it was. Seems right. It
didn't do that before. Got the warranties on the PCM too.

My it's been a long time since I posted this thread. 7/26/2006. It turns out
the above did not fix the problem. It reduced it in someway but didn't fix
it. We took it in a few more times at the dealer's request when they had an
idea about it. Finally, last week they had an idea that worked. The brake
light switch was replaced. After about 600 miles of driving later the
problem has not reappeared.
