False Alarms to Compustar CM7000-AS

+1 vote
Vehicle: 2015 Jeep Wrangler 
Alarm: (New-Install) Compustar cm7000as w/2W704r-sh long range 2-way RF transmitter 
Bypass Module: Fortin EVO-ALL 
 
The only wiring done outside the CAN-BUS are parking lights, siren, hatch trigger and 12v switched connections. 
 
- Doors triggers are connected through CAN-BUS; hood and hatch triggers are hard-wired into Jeep. 
- Compustar DAS Tilt/2-stage shock Sensor is currently DISCONNECTED from the brain. 
- DEI Proximity Sensor is currently DISCONNECTED from the brain. 
 
About 20% of the time my Compustar will go into full alarm within 5 seconds of arming the system. I thought the issue might have been the proximity sensor so I disconnected it completely. When that didn't work, I also disconnected the DAS tilt/shock sensor with no change (currently no external sensors are connected). 
 
After going into full alarm, pressing disarm turns off the siren but the parking lights continue to cycle through the full timeout period of 30 secs and the doors do not unlock. If I hit disarm a second time, the trigger cycle stops and the doors unlock but there are NO zone breaches indicated on the 2-way remote, by parking light or LED flashes as if the alarm never went off. 
 
When the alarm triggers, I can disarm the system twice, stopping the cycle, and immediately ARM the system with no repeated full trigger. 
 
Next, I disabled all triggers and unused options within the EVO-ALL with no change.  I finally disconnected the data wire from the EVO-ALL and I had not had a false alarm for one day.  I then reconnected the DAS Tilt/2-stage shock sensor and the DEI 508D Proximity sensor and haven't had any false alarms in two days.  This leaves me thinking the problem is either the EVO-ALL or there is something in the CAN-BUS that the EVO-ALL is picking up and causing the false alarms.  I'm hoping someone out there has a suggestion for me.
 
 
Thanks in advance for any help you can provide!

Sounds like something datalink related. Option F2 in the EVO is enabled which is perfect with Compu systems, just make sure the Compu is set to ADS protocol and that the datalink is plugged into the ADS port (the black datalink port and NOT the grey port).

 

This is where the TEST-ONE diagnostic tool would be soooo handy! You be able to see what's going on  via datalink and if a door/trunk/ status is being randomly sent from the EVO.

Hello AJ, it has been a while since this post, but did you resolve this?  I have two vehicles now with same issue, same set up, except one is a one-way remote kit. One is a Hyundai, the other is GMC truck, so the issue is not specific to a type of vehicle.  Found the alarm triggered full shock ONLY if the vehicle was remote started before being driven.

Since the original thread poster has not replied back after a solution was proposed, it normally means that the solution worked. Please try the steps that was outlined by Robb.
