werid issue with a 04 f150

I installed a Viper 5901 into a 2004 F150 yesterday. All went fine, it tested fine in the shop, etc. Got a call last night that it won't remote start without the alarm going off. Went out to the customer location today to check it out. It starts it routine to remote start just fine but as soon as it almost done cranking the alarm goes off and gives a "door open" on the remote. Upon troubleshooting it gets weird. It has 4 doors - 1, 2, 3, 4. All diode isolated, - trigger, all wired to the unit. Disconnect any 3 and leave 1, it'll work just fine. Hook up any other door and it acts up. I removed the diode to see if those were causing some issue - nope, still does it. If I disarm the alarm before remote starting it starts right up. I'm thinking about installing a relay to disconnect the door triggers while remote starting but it defeats the alarm. Any ideas?

Why didn't you use the + BLACK/ blue trigger in the passenger kick? That one will do all doors.

That wire is for dome light and it has a delay in it.

There is a  delay off on the domelight.  It comes on instantly.  Most quality alarms understand the delay off and will take care of it when the light goes off.

Yes as mr idiot said! Just program door trigger error off! That's why it's there!

This won't interfere with the dome light supervision I have hooked up? Humm... I've always been taught not to use a dome light wire that has delay on it and use the actual door triggers. What feature do I turn off on the 5901 to get it not to beep if a door is open when arming? Thanks.

I am not familiar with that alarm.  Even if you do not change it, if you arm it before the lamp goes out, it will probably chirp 3 times and when the lamp goes out, it will give you the 1 chirp.   The older alarms would just disregard the zone if the lamp was on.  Newer ones will monitor that zone and engage it when the lamp goes out.  Years ago, you could not safely use that wire if there was a delay.  The delay has become so popular, they have changed the alarms to accommodate the feature.

program the door trigger error chirp off if you wanna use the dome light

as for diode isolating the door trigers, did you do it correctly using 8 diodes?

Like has been said program the error chirp off, and hook up to the domelight wire. Helps to read the manual hah

Mr idiot, only audiovox systems chirp, three times and then once to indicate it is monitoring with delay active!

DEI products do not do this however!

Well it sounds as though DEI needs to get with the program.

actually, dei units (or at least i know the vipers will) chirp the siren once a few seconds after the arm chirp to alert the user if it sees a zone active such as a door or a domelight if used as a door trigger. hence if you turn off the door error chirp, it won't do that but will still monitor that zone after the viper sees it correct itself

Can anybody tell him how to disable the error chirp?

i can tomorrow. not from home though

1) Open a door (green door wire must be seeing ground during this procedure)

2) Turn igniton on the off (ignition wire must be connected)

3) Press and hold valet switch until two chirps are heard

4) Press valet switch five times and hold on that fifth press, when you hear four chirps, press the unlock button on the remote, you should hear two chirps, that indicates success!
