Am I getting F'D by the dealer?? Smells fishy?

I'm going to have to agree with John on the ECM - it should recalibrate itself without intervention - I think you can buy a used unit for around $100-150. It really sounds to me that they misdiagnosed the orignal problem and that the ECM wasn't bad - rarther the CEL was caused by the ABS sensor. I would call BS on this, get the original ECM and have it tested.

About the ABS - there's a sensor on each wheel and they shouldn't be difficult to replace. If they know it's bad, then the diagnostic has already been done and you shouldn't be charged for it - in any case most dealers charge $80-100 for a reading to get what code is being thrown. Once you know which is bad you can have it replaced or do it yourself.

This possibly falls into the flipside of owning a VX. Since people hardly ever see one, most assume it's some sort of exotic, and that as it's owner, you automatically have piles of cash on hand for them to liberate at their whims.

I parked near a Sears Auto shop at a mall one time, and came back an hour or so later with a tire that was almost flat. I'd never had problems with a leak before that, but you never know. I pulled into their garage and we aired up the tire and check for leaks with it still on the vehicle, all the while with them saying they could repair it and have me back on my way in no time. I never spotted any leak so I just told them I'd take my chances on making it home and keep watching it. It never went low again. Did they let the air out themselves (it was a couple of teenagers manning the shop that day) thinking they could make a quick $20 in the process? I guess I'll never know for sure. But it did make we wonder.

The history some VX's seem to have with wiring harnesses becoming shorted because of bad routing seems more likely than an ecu going bad, but other than that, I don't think I can add more than what's already been suggested.

Thanks for all the help....but can anyone actually tell me for sure if there
is any crossover/connection between the ABS system and the ECM where one could have shorted the other out causing my original problem?

Thanks

Let me share with you my experience with this. One day my ABS light came on and off she went to the mechanic. He tested the ABS hydraulic module - it was bad. I purchased another module (used) and brought it to mechanic. Module good.. ECM unit had a problem. The partition of the ECM that signals to the ABS system was out. I purchased another ECM (used). He put in the new ECM with the old ABS module -- still no ABS. My truck needed both parts to correct the problem entirely. I asked the same question, whether something happened between the two parts that caused them both to malcfunction. My ECM in every other way was fine. Just the ABS signal was affected.
