So everything was working great for a week or so... I was lovin' it. I then installed an aftermarket HU w/backup camera. I'm not sure if disconnecting/connecting the ground to battery so many times (to make connections for install of stereo) messed up the alarm/RS and maybe needs to be reprogrammed or if the stereo install is unrelated but what happens is when I use the key fob to lock/arm the vehicle the siren chirps, pauses, then chirps again and key fob says "door open". when I unlock/disarm vehicle it unlocks and chirps once. sometimes it will say "trunk open" but not consistently. when the system is armed the antenna led flashes 3 times then pauses, flashes 3 times then pauses, and keeps repeating. when I remote start the vehicle it will try to start but never turns over(kind of similar to what was happening prior to programming the tach as Howie suggested) and won't start. if I place key into ignition and turn to on position and then remote start it will start up but sounds like something is not turning off because it makes a strange noise and often turns off after about 15 seconds without me turning key to off position. all of my connections have been soldered and I don't think I could have disrupted anything while installing the stereo. I should also note that I accidentally turned the knob to 4wd while installing the stereo. I was then going through my checklist to make sure everything worked, the stereo, amp/sub, reverse camera, etc then came to the last check... verify the alarm/rs was still working and tried to remote start with the knob still in the 4 wheel drive position. it did not and that's when I first noticed the problems and haven't been able to get it right since. I checked all the fuses and they seem fine. I should also note that the dball2's led will not come on at all (red, orange, green, nothing). I tried to go through process of "module reset" for dball2 but that involves unplugging the d2d 4 pin harness, holding the reset button, and waiting until led comes on which never does. I should also note that when I left viper unit plugged in and only completely removed dball2 bypass I experienced the same symptoms. how can I verify if dball2 is getting powered or possibly fried? thanks for any help in troubleshooting this. I'm getting ready to move down south in 2 weeks, it's going to be hot, and I was really looking foward to this remote start feature!
