My viper 5900 has no reaction to someone touching it nor does the horn sound when it is armed. How do I set it to the most sensitive setting along with the horn sounding off upon alarming?

You have to make sure it is set up to sound the horn when armed. You can go into your information on the car and set it to sound horn when arming the system

I take help from online websites that have this service like helping in repair some like reliable-store have instant help.. others are a bit slow which I don't prefer... rest is up to us.. U get free manuals

You need to look under the dash for the model number then contact viper support

There is a sequence necessary to set the Viper every time you exit the vehicle: park the vehicle, put in neutral, place foot on brake, set parking brake,remove foot from brake, remote start vehicle with remote, remove key (vehicle should remain running), exit vehicle and close door, arm the alarm with remote (vehicle should shut down). The system is now set for MTS remote start. Test the system by remote starting the vehicle now (it should remote start at this point). If you open any door after the MTS remote start has been set, you will have to do the programming sequence again.This is a safety feature because something may have changed, i.e. parking brake released when the door was opened. You have to do this sequence each time you park the vehicle if you intend to use the remote start feature.
If this does not work, there may be an issue with the installation, i.e., the door trigger connection. Using dome supervision as a door trigger won't work because during the arming portion of the above mention programming sequence(when the vehicle shuts down), the interior lights will illuminate and the Viper will read it as a door opening. So, actual door trigger wires must be used.

I am having this same exact problem. Have you found a solution to this problem yet?

You have to find the clear mini shock sensor and use a philips screw driver to tune it up. As far as the horn that is a not a simple on/off feature, your installer would have needed to charge extra to do that.

small box under or around steering column. may have to remove panel under steering column or get lucky and may find it if you lay on your back on floor of driver area. look up underneath for a box 2" x 2" x 1" black box with an l.e.d. light on it. arm the vehicle and bang on steering wheel and look for the led light to light up and set off alarm. light will be red or green and will only light up during vibration.
find adjustment screw on it and turn counterclockwise.

try a couple of things, 1) try unplugging the anntena for the alarm for about 5 minutes. 2) remove battery from remote for 5 minutes 3) reprogram the remote

Look under dash for a small black box with wires coming out of it, about 2 or 3 inches rectangular.. there should be one or two screws on it. Look to see if it says which direction to turn for sensitivity. As far as not receiving, you need a new antenna, this is covered under warranty through DEI either bring back to where you purchased or look online and see where the closest dealer is to you...

Greetings Microluv,

Simple question, have you changed the battery in your remote lately? I was having similiar issues with my remote start and it was a simple matter of changing the batteries in the remote.

I figured lets eliminate the easy stuff first. :)
