I have a u0028 code and my car shows the ABS light and traction control light on the dash. A code scanner says it cannot communicate with the ABS computer system. I want to find which wire is faulty between the PCM/ECU and the ABS controller.

The U0028 code you are getting is set by the Restraints Control Module (RCM). It's not getting roll stability messages from the ABS module. First, clear the code and retest. If the code returns and/or there is still no communication with the ABS module, then follow the pinpoint test I have uploaded below. I hope this gets you started. Please let us know how it goes.
