I have a new vehicle and my GPS tracker is hard wired to 12V + The car, a Mercedes, has a battery monitor connected as standard to the ECU. What I am seeing is the feed to the tracker, after locking the vehicle is monitored by the ECU and after about 4 hours it sees it as an abnormal current drain. It starts to shut down the tracker every few minutes and powers it up again. After about 5 hours it shuts down the radio circuit it is powered from altogether. You ca see this happening in the logs. The only way I can think of is to power it from the battery +ve [post itself, bypassing the battery negative cable current monitor. BUT this makes disconnecting it trivial by anyone looking to see if a tracker is fitted. The device ID is 352887078466244 and it’s registered as a Concox GT06N As it is it works fine and by shutting down until the car is unlocked again saves potential long term battery drain, but is the way this thing shuts down in “jumps” going to be a problem to YOU at GPS Trace??? Many thanks for a great service I recommend you to any customers looking for a good service provider, commercially!
If anyone can think of a way around this issues with full time current draw devices on modern cars with current monitoring I would be very interested.
