viper 350hv shock sensor won't shut up

I have a Viper 350HV installed on my Jeep Wrangler, and all of a sudden the on-board shock sensor won't stop tripping the full alarm. I've tried adjusting it to completely off (knob all the way counter-clockwise) and it's still uber-sensitive. Tried adjusting it all the way in the other direction and still no change... everything trips the sensor. Slamming a car door next to the Jeep will trigger at least warning chirps. So as you all know, it's pretty annoying... and this is a new problem.

So I have an extra stand alone dual zone shock sensor that I can install in line with my 508D prox sensor, but first I have to shut off the on-board sensor, and in checking through the manuals, and searching the net, I can't find any way to do so. Is there any tricks to doing this? There is a note in the manual that I can bypass that sensor with the remote when arming, but I need a different remote, so that's out too. I have the cheap-o remote... but I'd like to shut it off completely anyway.

Any ideas?

Side question - if I tie the wires from a stand alone shock sensor to my 508D prox sensor wires, would I just solder in diodes on the prox sensor wires? If so, any special flavor of diode that I would need?

Any insight would be greatly appreciated.

Bumping this to the top.

Anyone have any suggestions, short of replacing the brain.

HaHa...that dirty little sensor will never learn.

Seems like there should be a way to bypass that sensor, just baffles me that they wouldn't but some provision in the menu to do so.

I do have a stand-alone shock sensor here, so I'm going to crack the brain open this weekend and see if I can fix the adjustment pot, or cut the trace. Seems like it should be easy to identify, but does anyone have a pic or diagram?

Quick update for anyone else who has this problem:

Took the brain out and removed the case. Adjustment pot looked ok, would still turn and stop at either end of the adjustment. So I plugged the circuit board back in (without the case) and tested the sensitivity of the shock sensor by tapping the sensor, and still had the issue. Played with the sensor plunger, looked like it wasn't frozen... then flipped the board over and on the bottom side by the shock sensor traces there was solder splatter from when the board was made. I scrapped it all off with my fingernail and seems like the problem is now gone.

Odd, since the alarm has been installed for like 9 months, and this issue just came up last week. But for now (knock on wood) it seems to be working correctly. Time will tell.

After further testing I don't know that the internal sensor is working correctly. It's definitely not triggering the full siren at every noise anymore, but now unless I turn it to the least sensitive position, it will chirp at everything. I beat the crap out of my jeep during testing and I can only get it to chirp back, no more full siren. So I may just turn the onboard sensor to its lowest sensitivity, and run the stand-alone sensor. Thank you for the info on the diodes!

See, I've always secured my alarm brains tight, but the install manual on this one said specifically not to screw it down, so I didn't. When reinstalling the brain (after my testing) I secured it with industrial strength velcro, so now it's more solid than the caluking I used before, and it seems like the sensor is now working more consistantly. It just doesn't trigger the full alarm!

This is definitely the most finicky alarm I've ever owned.
