Need help interpreting Carsoft codes

I have a 2002 530i, the DSC triangle and Brake light are lit. They have been lit for quite a while now, and never has the ABS light been on. I have searched to see if I could get a start to where the problem is, but I've noticed most people have the problem involving the ABS as well.

So currently, DSC does not work, ABS does work, Cruise Control does not work.


I have some shots I took from carsoft, but need your help in what they mean.

What did the test of the wheel speed sensors (key out of the ignition, ABS harness cable disconnected) show for the four wheel speed sensors?

Here are my results, by way of example:

This one is easy- your module is toast. communication fault, unless you do not have key in position #2

I havent tested the wheel speed sensors.

If my module is toast and I swap one from another E39, would that automatically fix that? I've heard that it has to be coded to the vin of the car, anyone know if thats accurate?

Takes only five to fifteen minutes with a DMM and celery ties.

Yep. But you have other options:

Basically yes - but there are specific exceptions:
- What happens if you don't code the VIN into a new or used ABS control module

I have another e39, it's a 2000 528i. The module is still a Bosch 5.7. So I swapped all the speed sensors on all four wheels and that did not solve anything. But when I swapped the module over, the brake light went off, cruise is working(ABS was never on), but the DSC triangle is still on. Wondering if its because its not coded.

Of the systems I can test on carsoft, I am not getting any codes either
