Disabling PSM in a 99C2

[mark_d_mcguire]

Has anyone permanently disabled PSM in a 99 C2?

I located a car to rebuild my race car, but is has PSM.

If I have my computer and ABS controller from my old car can I swap parts to make it work?

Anyone flashed the computer to disable?

I am a nubbie on this ptopic and could use some advice. Couldn't find anyuthing in my serch.

If you replace the ABS/PSM controller and hydraulic unit you will be most of the way there.

But you will have one extra line. Compare these two diagrams and perhaps you can see what else needs to change.

Thanks for the info.

It's interesting that the hydraulics are different. I'm assuming I can modify the lines to combine the rear circuit.

What happens when the control unit gets disconnected from the DME? Anything more than a warning light?

I don't know - It does not seem like you have to do anything if you switch ABS control boxes.

Loren, thanks.

It is interesting the the DME is shown in the TC diagram but not in the other one.

I was talking to the librarian about purchasing a set of manuals. Would there be a description of that connection somewhere in there?

After thinking about it, this does seem pretty simple since I have the hardware.

Before I go there though, does the TC activate once the ABS kicks in like later PSM, or is it really turned off with the switch?

The service manuals have a functional description of all the ABS, ABS/TC, and ABS/PSM systems used in the 9x6 cars. They also have troubleshooting.
