APS-996a false alarm problem

Everything works great, except for some reason, when doors are locked (alarmed armed), when remote started, the alarm goes off.  Did I hook up something wrong, is that why the alarm isn't shunted during remote start?  Please help.  Thanks guys for a great forum

Your shock sensor is causing this problem! You need to use the light blue wire with a relay to bypass the shock sensor. Check the installation manual for the LT blue wire connection and how it gets connected to disarm the shock sensor during remote start. It has been a long time so I do not remember.

Well I am almost positive it is the shock sensor. As with prestige, they dont bypass the shock sensor during remote start automatically. As with viper, they bypass the shock sensor during remote start operation and the alarm still remains fully operational. I ran into this issue with almost all of the prestige's that I installed. Aps-786,Aps-996 ect...

Thanks alot guys, I appreciate it.  I guess I took it for granted that it automatically bypassed it.  Seems kind of silly not to do that.  Anyway, I appreciate it.  By the way, its on a 96 Cav.  Thanks again

Audiovox automatically shunts the shock sensor during remote start. Look at page 14 of the install manual, they have it written under the the description for the 4pin shock sensor.

The lt.blue wire is for 3rd ignition or aftermarket shock sensors that do not get shunted during remote start. This has always been the way with audiovox. Even on an older APS-775 that I just put in has the sensor shunted during RS. You seem to be having a different issue going on. Do not introduce the lt.blue wire into the system. You risk frying the shock sensor and the brain..

Metaverse,

I beg to differ. To boot the lt blue wire can be used for a bunch of things (not just third ign.). I have installed plenty of prestiges, and all of them need the shock sensor bypass. APS-776, APS-996. But I do know that there was a couple of different versions of the 996. I cant argu if the manual says so, in which none of mine did. Pluse the light blue wire is a 200ma ground 3 sec before, during, and 3 sec after remote start. Please intrduce me as to how the brain and/or shock sensor may be fried!

First off, every audiovox has this feature, period. APS-775, 786, 996, to mention a few. I just installed an APS-775 two weeks ago which was made in 1998 and it had this feature..the 996 is it's successor which came out in the 2000+ The manual located here the official one I downloaded from audiovox's website. I know there are iterations of 996A, 996B and 996C's..but, this info is from the model the user mentioned. The shock sensor is always a 4 wire..always has been. Unless it is an old clifford with no pre-warning and just straight full trigger. You even had to run a power and ground on those sensors since they only tied into the brain for full trigger.

How you can fry a sensor is by introducing a negative trigger with a positive line. The install manual does not mention how to bypass an aftermarket shock sensor. It just says the lt.blue is a negative trigger that can be used for that option. It clearly states for a non plug-in sensor which is aftermarket. I mentioned "RISK" frying a line since the user could possibly wire it wrong by tying it into a power line on the factory plug-in shock sensor.

I'm no expert, nor do I do this for a living..yet, I install so many at this point maybe I should. So, i'm going to take a deferred stand. This is a no guarantee, informative website. All I can say is go do what you have to do and good luck with whatever you do. I'm just here to compare what is in my head and from experience from hand's on and picking the brain of experts online and onsite. I always backup my info where I can. Good luck..
