module was replaced but, how's the wiring harness and pins look? That code means the PCM is not receiving the expected signal from the ABS module by the allotted time. It basically times out before the ABS module says "Hey, i'm here and working".
Dealer replace that under warranty?

Every look up says that code is for a mirror control module, but after
more digging:
U0514 - Solenoid relay abnormal connect, or solenoid circuit open.
U0514 - Invalid data received - anti-lock brake system (ABS) control module
Wiring, Wheel speed sensors, Defective ABS control module, Defective ABS pump, PCM
The car will stop without ABS, so don't worry that your breaks will fail, they
will not.
Some common causes of code U0415 could include the following-
Damaged, burnt, shorted, disconnected, or corroded wiring and/or connectors in the ABS wiring harness.
One or more defective or malfunctioning wheel speed sensors, but note that this condition will almost certainly be indicated by additional codes that are related to individual wheel speed sensors.
Defective ABS control module.
Defective ABS pump.
Failed or failing PCM; Note that this is a rare event, and the fault must therefore be sought elsewhere before any control module is replaced
The PCM requires valid data from the ABS system at all times via the wheel speed sensors in order to be able
to control the brake -, and other brake-dependent system in a safe and effective manner. Thus, if the PCM
detects input data from the ABS that is implausible, or invalid in any way, it will set code U0415, and also
illuminate a warning light. Note that on most applications, the PCM will also disable or deactivate the ABS
system until the fault is corrected.
The module was replaced, now you have to move on to the wheel sensors, and
pump, or wiring.

Hello there I was wondering if you've gotten this fixed I just had issues with my PCM it was put on the bench and reprogrammed by my tuner.. the Advanctrac, ABS come on and say fault but then go off after a minute. Comes on after a couple minutes of driving then goes off any ideas.. I have had the wheels off the front I installed the vmp triple pass heat exchanger and a 79mm pulley and 170°t-stat.. any input will be helpfull.. and sensor or ring or maybe faulty wire or since the pcm was recal maybe the ABS and advancetrac modules need recal???
Well replacing the wheel speed sensor and hub assembly fixed the problem. Not sure which as the work was performed under warranty at the dealer. The lights that we’re being displayed on my dash we’re constant
