problem with Viper 791XV

iv only had this a few times, but my valet led like blinks twice and waits like 5sec. then blinks twice again. And if i start to drive the car the alarm goes off.

The alarm is telling you something.... it is in a code of sorts. Check page 37 of the owners manual.... If it goes off when you drive away, it isn't disarmed. (And starter kill wasn't obviously done) Gus PS: If it was professionally installed, take it back to the shop that put it in. If you put it in yourself, double check connections. Wherever I go, that is where I end up......

Unless he's remote starting (but not disarming) the car when this happens. In that case, it's behaving appropriately when he hits the brake, the R/S disengages, and it "sees" 12V on ignition when it shouldn't... It sounds like your shock senser is getting triggered. This could be because A) Things are hoooked up wrong B) The shock sensor is too sensitive C) The brain needs reset or is having a meltdown D) Someone's messing w/ your car. In cases A), B), and C), the correct answer is to have whoever put it in fix it. If that's you, check your connections and the sensitivity of the shock sensor... Try disconnecting the harnesses from the brain and replugging them in. Me

Check your ignition connection also,  your alarm shouldn't go off while you are drivingDo it right the first time

well idk, i hooked it up myself and diddnt get a strait shot at it all. So ill be working on it. But all i had to do was lock then unlock it, and also sometimes when i click the unlock botton the buttons go up just a little then go back down??

What car is this? Me

86' mercedes 300E, also is there a way to diarm the alarm if i use the key to open the door. my dad has a merceds shop so i kinda just need to check some of the wiring books he has, or just ask him
