Crazy VATS Problem
 

Ok so I seem to have this reoccurring problem with my car not starting. Originally I thought it was due to the fact that I cut off the battery when ever I leave the car. Some folks on the forum thought this may be messing with the VATS system thinking there is a problem. Every tome this happens following about a 20 minute wait she will start right up. The only other thing that is constant in all this it only ever happens when I am at the gym. Yesterday I came to the gym and did not cut off the battery this time. When I went to leave sure enough the car doesn’t start. I waited about 15 minutes and it still would not start. Called my wife for lift and went back about 1 hour later and it started without issue. It was then I noticed I always park under some high tension power lines and was wondering if the magnetic fields created by these things may be messing with the VATS system. It makes no sense at all that it only happens ever at the gym. I always park in the same spot.

I see 95 and 92 ZR-1s on your signature line. Is this happening to 95? If so, this is while using PKE remote?

Re: Crazy VATS Problem
 

It is the 95 but not sure what the PKE remote is?

Re: Crazy VATS Problem
 

93 to 95 ZR-1s (as well as standard C4 Corvettes) came with proximity remote fobs - a.k.a. Passive keyless entry.
I’m wondering if you lock/unlock the door with PKE remote, if VAT will still malfunction as you are experiencing.

I just use the key to unlock. But it never happens any other time.

The fact that it started in that same spot 1hr later would tend to eliminate the power line hypothesis IMO.

Just a guess. Doesn’t happen every time I take it either. I don’t think I can rule it out until it happens somewhere else. I have read elsewhere in the forum that if this VATS system sees anything odd in the electrical system, could be enough to trigger. That is why all fingers initially pointed toward my battery disconnect. May take it today to see what happens.

Is there a way to just turn this system off?

Re: Crazy VATS Problem
 

If this was happening to me, I would splice in a VATS bypass and see if this eliminates intermittent issue. If yes, i would suspect periodic CCM malfunction.
Did you notice what the security light was doing on the main cluster?

Re: Crazy VATS Problem
 

When the door opened the light blinked. When I turned the key to energize the system (but not start the car) the light was Off.

Is there a thread that describes how to do this? I am also considering putting a resistor into bypass the key pellet. From what I understand there is a 2 wire connector under the dash near the column that can be disconnected and bypassed with a resistor of the same ohms as the key pellet. I urge everyone to measure the resistance across the pellet on their keys so if they ever lose them, bypassing can be an option. doubt these keys are available anymore.
