I don't have much interest in this alleged "fix"; tuning the brake controller module to simply have the warning light come on sooner does nothing for me. Either replace the pump correctly with the part that superseded it, or stop wasting my time with a tune that obfuscates the root problem.
We just had our Buick Enclave into the dealer (for the 6th time in the 1 year we've owned it,) for a stupid recall to fix a potential issue with the transmission clutches potentially dragging after an auto start/stop sequence that I am already irritated that I cannot disable in the first place.
