Re: VZ Body Control Module
The ABS fault warning without throwing a code would suggest low voltage either from the alternator or to the cluster / dash / BCM themselves.
Are you familiar with Diagnostic Mode on the trip computer? I am fairly sure it's MODE and ^, hold them down when you start the engine, you can then cycle through a heap of 'hidden' parameters. Find the battery voltage one and keep an eye on it.
It won't help if the whole cluster drops out, but may help keep an eye on things sometimes.
A friend's VY did the same thing, albeit not dropping out completely, and it was the regulator on his alternator.
