Ford B1342 code diagnosis – What’s the best way to fix this?

[Nicko]

B1342 code on my 2011 Ford Fusion popped up, and from what I’ve found, it’s related to a failure in the control module (ECM or ABS module). My ABS light is on, but the car drives just fine. Should I be worried about this? Is it safe to drive, or am I looking at a huge repair bill? Anyone else dealt with this before? Let me know what you did to fix it.
