The info I posted is straight from disassembly. That is the usage of traction and how it is handled by the pcm. Linking the code with platforms is not an easy task, so thanks for figuring that part. I suspect the frequency input was designed to allow abs to request specific not only retard but how much of a retard. ANyway it seems overkill left over for something more complex.

B22 might be configured in the calibration how to be used. I need to check that out.

Does anybody knows if that ICE mode is only bosch related, or is experienced on other abs modules. 98+ fbodies also come with bosch abs.
We can also make that statement. Bosch= built to brake. AC Delco= built to last.
