Hello,
I belive you mean BCM-0094. This code is for communication problems.That seems to be an awful lot of things to replace.

I am sure this communication problem is the cause of the car shutting off.

Does the car have any other codes besides this BCM-0094?
Customer: replied 8 years ago.
yes it has ecm code 310a rpm and 300a cmp thats all the codes
Expert:  Michael replied 8 years ago.
Getting code ECM-310A will mean the car will likely die. This is the engine speed sensor and the engine will die when the signal is lost.

This could be a faulty sensor. Has the engine or transmission ever been out of the car?
It could be a fult in the wiring.
It could be a lttle surface rust on the flywheel causing interferance.

I see you have replaced the cam sensor. Has the Crank or RPM sensor been replaced?
Do you have a screen shot of the RPM sensor with the engine running?
Customer: replied 8 years ago.
i have replaced the rpm sensor the motor and trans are original and never been apart. The car had 76k in 2006 when the problem began and know has 105k in 2008 with the same problem. i do not have a screen shot of the rpm sensor.    The way i am heading is to replace the climate control module the can network runs through this module with the stc for the abs. what do you think.
Expert:  Michael replied 8 years ago.
The CCM should have no effect on the engine.
Here is the high speed CAN. The throttle module, ECM, ABS module, Central Electronic module are the ones that could effect the engine.

Does the 310A code return after being cleared?
Customer: replied 8 years ago.
yes the 310a code clears and the only code that is a hard code is the abs0094 the 310a code is only seen in the advanced screen of vida and it says 310a ereased.
Customer: replied 8 years ago.
but the abs0094 code will also clear
Expert:  Michael replied 8 years ago.
I would unplug the ABS module and drive it around. See if the 310A returns.

Was the crank sensor unplugged to cause the code?
Has it been replaced?
Customer: replied 8 years ago.
there is no crank sensor in the car. I can do that with the abs computer.
Expert:  Michael replied 8 years ago.
Yes, It will set codes but the engine will run without it.
I have had a couple ABS modules that would kill the engine.

You will want to put the crank sensor in or it won't go far.
Customer: replied 8 years ago.
so you think it still could be the abs computer
Customer: replied 8 years ago.
the crank sensor i refer to is the rpm sensor and yes it is plugged in
Expert:  Michael replied 8 years ago.
I think the 310A was killing it in the first place.
You can leave the ABS plugged in for right now.
Make sure all the codes are cleared out. and drive it around.

Let me know if you have any codes return.

Do you have any other questions for now? I am headed to bed soon. I will check up on this tomorrow otherwise.
Customer: replied 8 years ago.

Expert:  Michael replied 8 years ago.

I wil be waiting to hear back.
Expert:  Michael replied 8 years ago.

Can I be of any more assistance to you?
