crimestopper cs 2900

Does anyone install crimestopper? I have a question about the CS-2900. My unit when locking sends a unlock then a lock pulse. When unlockng it sends a lock then a unlock pulse. Does anyone know why?

It is in a 04 Nissian Maxima. I used the CAN-SL2 bypass. The remote starter is sending an oppsite pulse before the one I want? I have installed alot of other crimestopper units but never the CS-2900. None of the other unit worked like this. The matter fact I pulled a 2016 of the car before putting the 2900 in.

I've checked all the wiring diagrams that I have access to, and it looks to me that you may have the lock and unlock wires backwards. It also looks pretty diffucult, because they also say to "Test the wires by turning the key in the door lock cylinder" which I obviously can't do. Try going back and checking the wires again. I'm sure you did it right, but humor me and double check, then let me know.The Only Stupid Question, is the one Un-asked

Wires are correct. I just removed a 2016 from the car (which was working fine, just wanted to upgrade) minutes before installin the 2900. When I press lock it does lock, when I press unlock it deos unlock, but it does the oppsite first. When lock is press the RS unlocks the doors then locks them. When unlock is press it will lock the doors then unlocks them. The RS is sending 2 different signals one right after the other. Make sense?

Yeah, that helps a bit more.... I'm thinking that you have both the Green and Blue Wires for the lock/unlock from the brain... I'm reading that you have a Negitive locking system, lock from single pulse and unlock from double pulse..... Try this......    grab a Digi multi meter and check wich wire gets the double pulse,  after you hit unlock.... only use that wire. Make sure that it's a neg double pulse thats being sent... If that doesn't work, let me know, and we'll go from there. Sorry I haven't been much help thus far, I'm trying though!  good luck!The Only Stupid Question, is the one Un-asked
