viper 5204 on 03 sierra

Looking for a bit of advice – recently finished installing a Viper 5204v with the idatalink ADS-AL(DL)-GM1 (flashed as necessary) on my 2003 GMC Sierra 1500 4x4. Installation / wiring connections are indicated below. Everything (remote starting /dome lights / parking lights / accessories, etc) works fine – the one issue I have is that the driver’s door unlocks when using / activating the remote start. I have programmed the Viper security features as follows: Menu 1 (Security) #6 – Door Lock Pulses = Single Menu 2 (Convenience) #7 – OEM Alarm / Disarm Output = With Unlock (to be sure, if I open the door after remote starting the alarm will go off) Menu 3 (Remote Start) #16 –Remote Start Safelock = Off (If switched to “on” both doors unlock asopposed to just the drivers door). Anyone have any insight or a fix for this – it’s a bit unnerving.

Hi Kreg, Got it figured out (right after I started a new thread on the issue) OEM Alarm Disarm Output (Menu 2 Convenience #7) should be set to "Remote Start Only. After I did that everything worked fine. The drivers door does unlock momentarily, but then immediately locks after the truck starts. Thanks again. -RRoadGlide2459

Try unhooking the factory alarm disarm wire and see what happens. Otherwise you cold grab a second status wire. And have it pulse after startup and pulse the lock wire to relock the doors

Doesn't this system have the Smart Lock feature? It locks the door during remote start. Menu 3, Item 16, Option 2.When all else fails, Read the Instructions

i think pentavolvo is right. when the RS activates it pulses the factory disarm wire causing the factory alarm to do a drivers door unlock as "part one" of progressive factory unlocking. yuk

If your system moves you physically and not emotionally, you have wasted your money.

Pentavolvo - thanks for the reply. Would prefer not to disconnect the factory alarm / disarm wire as the way the system is currently wired I still have full OEM key fob functionality. Not quite sure which "2nd Status Wire" you are referring too. Thanks again. -RickRoadGlide2459

Smokeman1 - thanks for the reply It does have the Smart Lock feature? However if I chose option 2 (on)both doors unlock during remote start as opposed to just the drivers door (with option 1 (default - off) selected. Thanks again. -RickRoadGlide2459

Hi Kreg, I spoke to soon - still having the same issue. Have verified the W2W connection between Viper H2/4 GREEN/ Black to ADS AL-CA 10 Pin harness, Pin 4 Brown and also verified that the Viper is not set to OEM Alarm Disarm Pulses = 2 and the Door Lock Pulses is not set to Double Unlock Only. Also tried turning Remote Start Safelock = On, however then both doors unlock as opposed to just the drivers door (when remote starting) Not quite sure what to do at this point - I reset the Viper to factory defaults (and then programmed for the automatic trans and also the hard wired tach), but I still have the same problem. To be sure I can still lock the truck after remote start by pressing the lock button on the key fob so it's more of a nuisance issue than anything - sure would like to figure it out though. Thanks again for your reply. -Rick RoadGlide2459

Slightly off-topic, but does anyone know how cabin temp is reported on the Viper 5204LE (my remotes do not have a display but was under the impression that pressing the function key would cause the LED to light periodically as temp increases / decreases) Have turned on Menu 3 #15 "Vehicle Auto Temp Report" but am not getting any indication of temp changes on my 2-way key fob. -RickRoadGlide2459

Hello, Does anyone know how cabin temp is reported on the Viper 5204LE (my remotes have LED's as opposed to a display but was under the impression that pressing the function key would cause the LED to light periodically as temp increases / decreases) Have turned on Menu 3 #15 "Vehicle Auto Temp Report" but am not getting any indication of temp changes on my 2-way LED key fob. -RickRoadGlide2459
