Alarm wiring diagram 2003 Jetta

All VWs sold in the US come with standard keyless entry and factory anti-theft system.  I have a 2002 Jetta and, as far as I know, it is the same as the 2003.

When you press the "lock" button in your remote (or when you turn the key on the door) the parking lights will blink once and the buzzer (it is a high-pitched "beep" sound, louder inside the car) will make a brief noise once.  When you press the "unlock" button on your remote (or when you turn the key on the door) the lights will flash a few times, disarming the system.  The regular car horn should never beep (that is a lower tone outside the car).

Also, if you unlock the car but you do not open any doors, the car will lock again after 30 sec or so, the lights will flash once, and the buzzer will beep once, as if you had pressed the lock button again.

Now ... your post was not specific as to whether you are having problems with the factory system or with an aftermarket alarm system.  Since your car is less than a year old, if you have any doubts, you may want to contact your dealer about the malfunction.  If it is an aftermarket system, installed by a professional, you may want to see them and explain the problem.  If you installed it yourself, we will need more details about what is happening.

Then I would go up to the aftermarket alarm installer and point out he/she interfered with the operation of the driver's door lock module.  If you go back to the dealer, they will probably not honor your warranty, since the vehicle has been modified.

I am also confused about the statement "goes into sleep mode".  If the Viper alarm is in "sleep" mode, is it still protecting the car?  If it is not, then it is really not doing anything other than annoying your life ...

The operation you described doesn't sound right.  You shouldn't have to use two remotes in that sequence.  It sounds like this was a hack job.  By the way, may I ask what is there to gain by adding a second alarm?  The factory one will prevent the vehicle from being started.  Are you looking for additional triggers (glass sensors, motion sensors, etc)?  Are you looking for a louder buzzer (since the factory one is loud inside, but moderate outside)? You already have anti-theft, keyless entry, and an alarm from the factory ...

rte, factory alarms are great in being allready in the car. The problem lies in range, factory keyless works at most up to 30feet. A new viper, 1000ft+

I was interested in the remote start basically they just keep giving me a new one when I switch vehicles for free so why buy something else.In the alarm system again.The viper doesn't go into sleep mode it is the factory system they goes to sleep mode when you try to open the doors.The viper remote will not work at all just the factory one.The viper alarm disarms including the factory one but the doors remain locked.Do you think a blown driver module would cause the viper keyless entry not to work properly??And cause it not to open the doors.The installer which are reputable in my area had nothing really to go by there is no exact wire diagram for a 2003 if you can find one for me e-mail it to me.   So what do now is when i remote start you have to manually unlock the car with a key it doesn't unlock with the viper remote.If you arm the car the doors lock except the drivers door After ten seconds you can disarm the alarm but the doors remain locked understand If you have any idea or if you think the module is screwing this up  let me know?

I have an update.Here it goes. I start my car with the 550 esp viper I go to unlock my doors using the viper remote they all open.OK. Next I don't remote start my vehicle,it is not running I go to open my doors with the viper remote.They don't open.But the alarm disarms.OK. My doors always lock with the viper keypad remote.The only problem I encounter is that when you try to open the doors when the car is not running they don't open at all with the viper remote.It is like my factory alarms door lock are asleep to save energy and the viper doesn't understand.The only way you can open the doors with the viper is to wake up the system with the factory remote by hitting lock the using the viper remote the will unlock. Somehow I think a pulse needs to be sent to wake up the system..

Let me know if this makes any sense I think this is a new problem with the 2003 models.By the way I have a 1.8T Tiptronic and the color of the wires from the module are yellow blue stripe and yellow green stripe..The module is being looked at by volkswagen service tommorrow .

if the factory keyless goes to sleep it needs a relay ta wake it up i dont know how but i seen it done. ask ur installer if thats not it the viper should have a factory disarm wire output ta shut  off the factory alarm/keyless

If any one else can throw some feedback it would be great..Also if you fing out how to wire that relay with exact wire colors and were it would be helpful..

I think your problem is simpler then you think.  The car requires two pulses on the unlock wire to unlock the doors.  The first one disarms and the second unlocks the doors.  I only skimmed through this quickly so if I missed anything I appologise. 

Dear Bmline,

Your problem have more simple decision, from this, which these people here recommends you. Your best way to control the original alarm in the vehicle is to connect the wires from your Viper alarm into the drivers door to the wires coming from the keylock. This is the only way to remote the factory alarm, because inside the door the signals are coded in only one wire. That`s the problem. Don`t try to connect your alarm to the drivers door motor for central locking, use the wires inside the door before they goes into the fabric module for the window motor and central locking module. All this reccomends of other guys like rti3tdi are bull sh*ts (i`m sorry for my strong words), but they havent good experience in this european vehicles, how i can see from their answers.

Good luck !
