What happens that you need to press the reset button?

If I had to guess.... It sounds like the "secret connector 2" wire is not grounded correctly. If I had to guess.

When the Z1 is new, you can ground just the parking brake and it will work with just that. But as it learns the vehicle is moving while it calibrates the system it will start locking you out when you sense movement. When you ground the connector 2 wire it will tell the Z1 not to listen to the movement.

Once it locks you out, do you turn the car off and then on again... sit still and do something, when you start moving, almost immediately you get locked out?

I don't know but it might pop up a warning message about the parking brake... does that pop up?

Sounds like you don't have a proper connection on the "secret connector 2" wire.

Yep, if you have that warning pop up and when you just stop everything works but when you are moving it's locking you out....

The wire that you need to ground on connector 2 is not grounded.

I don't know if you have the wire in the wrong place, or the wire is in the correct place but not pushed in all the way, or the wire is not grounded at all (possibly all 3). But it's something to do with the fact the wire on connector 2 that I show in that web site needs to be grounded and it isn't.

With what you describe, the parking brake wire is grounded... all you need to do is look at the connector 2 wire.

I also have the same problem. Bootup seems fine without any brake message. After 15-20 minutes of driving, improper brake connection message pops up and unit does not bypass anymore. After resetting the unit, it's good for about 10-20 minutes then the same happens. I think it may be the second wire also. I had trouble getting the cell mute wire out of connector so I cut it, stripped it and stuck it into the hole in connector 2. That may be the prob? Maybe the vibration from driving caused the wire to lose contact somehow? I just tried again to get the cell mute wire out and finally got the wire out of connector 1. I spliced the wire back and snapped it into the bottom right hole in connector 2. Hope it works now, but won't be able to test it out until tomorrow.

Yes, if your Z1 was made in July 06 and newer then that was your problem. Let us know how your new fix works out.

Thanks guys I will also try tomorrow and let you know, Not going out now as I will freeze my butt off, 46 here in Florida ..I here ya ..ahhhhh :P

Good luck!

After 2 hours of driving, so far so good. Still got my fingers crossed........................

Can you buy those little metal female connector clips for that size wire , so you can make your own ground / if so what size and what do you call them? I went to radio shack and they did not have anything like them in that size..

you can buy those ends and put them on a wire, but you will need to order them from [url=http://www.digikey.com">www.digikey.com or
