xk01 causing gmrc01 to chime excessively

A local installer put in a Viper 350HV in my 04 Avalanche this past week. Previously installed is a Kenwood headunit with a GMRC01. Other than described below, the GMRC01 functions as it should, chiming when seatbelts are not on, doors are open, lights on, ect. The installer put in an XK01 to activate the door locks when the alarm is armed/unarmed, but that is where the problems start. After installation, every time the alarm is armed, the GMRC01 chimes excessively and won't stop until the key is turned in the ignition. Disarming the alarm or unlocking the doors with either the factory remote or key do not stop the chiming. Additionally, the door locks pulse once to lock when the alarm is armed (chiming begins immediately) then about 3 seconds later, they pulse to lock again. In order to isolate the problem, I had the installer remove the XK01 and cycle the alarm. No problems with the chimes. Obviously the doors didn't lock, but we know the Viper's light functions and such are not causing the chiming. While the alarm was armed, we locked and unlocked the doors with the factory remotes and keys. No problems there either. The factory remotes cycled the locks only once as they were supposed to, and there was no chiming. Clearly, the Body Control Module is getting some kind of signal to lock the doors from the XK01, but I'm thinking the BCM is interpreting the signal as a problem, resulting in the chimes going off. I had another installer in the same shop go over the wiring, and he couldn't figure out any problems, so I have no idea where the issues could lie. I just want my alarm working the way it should. Any suggestions?

did they hook up a factory alarm disarm?

xk01 isn't designed to work with non oem data pieces, mind you not many are. I've installed decks in trucks and lost tach output on idata modules. did he try installing the stock deck, programming the xk01 and then reinstalling the gmrc01?Shaughn Murley

any solution on this issue Have an 05 Hummer doing the same thing only does it when you lock/arm the alarm FYI GMOS-01 Amp intergration and xk01 for alarm

did sum installs on late chev vechiles (05-08), and had the same issue....also was using the XK01.  Talk to my distributor, and said..."u have to download the NEWEST Firmware to the XK01"...they had problems with the unit in the past, "with the chiming issue" and released a program, to solve the problem. U can got to flashlogicvip.com, and it states the problem there, and how they fixed it...the 1701g, already has this "new update", so the issue is not a problem there, if u use the 1701g.born to install

thxnk you all for the reply I end up with a 1700G and a happy costumer
