drober30 Posted September 4, 2006 Report Share Posted September 4, 2006 My AVIC Z1 is bypassed with a TR7, actually two TR7 because I have auto headlights. After driving my car for a while the parking break message comes up and my system is no longer bypassed. I searched the forum because I thought this happened to someone else but I could not find the post. I had this professionally installed and they wanted to use the TR7. I have reset the unit before but it keeps happening. Any ideas? Quote Link to post Share on other sites
ducatiboy Posted September 5, 2006 Report Share Posted September 5, 2006 Hit MENU-SETTINGS-HARDWARE-CONNECTION STATUS And look at the status of the parking brake connection. Is it ON all the time? If so, that's your problem. Even with 2 TR7's you will need to disconnect your parking brake wire. You don't want it grounded all the time. I'm going to guess that's your problem, disconnect that wire, and then reset the unit and those 2 TR7's should work just fine. Quote Link to post Share on other sites

I started the car and it immediately came up with that message. I will call them and tell them I want your circuit installed. I will ask them if I buy it if they will put it in. I'm sure they will their real good guys. I have two vehicles so I will be ordering two circuits if they will. Another question: I had one installed in my 05 Trailblazer last week and the tech said he could not get the illumination to work because there was no 12v just a pulse or something like that. I thought I read that with your circuit it didn’t matter that it would work with these new pulse/canbus systems? Quote Link to post Share on other sites

There are 4 levels of resetting. You might want to try them all. Usually just the recessed button to the right of the eject button will get rid of that message... Unless they programmed and installed the TR7's wrong. [quote name="drober30"] I will call them and tell them I want your circuit installed. I will ask them if I buy it if they will put it in.

Just that with my circuit there is no programming and, I would like to think, an easier install. [quote name="drober30"] I have two vehicles so I will be ordering two circuits if they will.[/quote] Feel free to order some, but if you already have TR7's those should work, there is a sticky in this forum with how to install and program them.

My circuit is smart enough to watch a "dimmer" signal and activate the Z1. The Dimmer wire is a pulsed 12V. It is 12V for 1/1000 second and then ground for 1/1000 of a second. Your dimmer knob will vary the time on and off to adjust the dimming of the interior lights. I tried to program my circuit to work of that signal and make 12V while it sees that signal. Canbus is usually more of a command signal. When you turn your lights on the system sends out a "hey I turned on the lights" and then that's it till you turn off your lights and then it sends out a "hey, I turned off the lights" signal. My circuit and the Z1 won't work with this, we need at least something all the time when the lights are on. There are canbus adapters out there, that will watch for these commands and send out a constant 12V output until it sees the "hey I turned off the lights" command. It's something to consider.

Can I trouble you for the other reset levels you mentioned? I know there is one in the menu that says reset to factory. Quote Link to post Share on other sites

I think one is MENU-SETTINGS- in there somewhere. And leverl 3 and 4 are something like hold MAP when you turn on the car and there are 2 in a secret pop up menu. Just check the manual for that to be sure. Quote Link to post Share on other sites
