Difficult to say without any context. What is the entire fault code? Or even better, a complete autoscan would be good (see below).

It means that at some point, the ABS module received data from the AWD module that the ABS module didn't expect, or didn't know what to do with.

Since the AWD module itself shows no faults, I'd work on the Steering Angle Sensor fault first. What do you see in the ABS module's MVB 004.1 with the wheels pointed straight ahead and the steering wheel centered? What happens as you turn the wheel left and right from center?

Changed code but after doing basic settings in G85 , 200 201 and G251 it won’t “stay”set comes back as No or incorrect basic setting /adaptation
That’s the only code coming back in 03

New code of 0000607 cleared the wad “implausible signal “ but I still have abs , esp and flashing brake light but the last one is intermittent, the code remains as no basic setting or adaptation
