Increased Battery Discharge and aftermarket installs
I have installed the following:
1. Escort Radar hardwired with laser jammers 2. OBD-2 Port bluetooth module 3. Wifi Back-up Camera Car says Increased Battery Discharge (car is 3 years old, in South Florida, driven almost daily) Tech at dealer states: 19442 BATTERY LIGHT IS ON. CHECKED FAULTS AND FOUND FAULTS FOR INCRASED BATTERY DISCHARGE RAN TEST PLAN FOR ENERGY DIAGNOSIS CHECKED AND FOUND THAT THE CAR HAS BEEN WOKEN UP 32 TIMES WITH AN AMP DRAW OF 80-200mA. CHECKED THE CAR FOR AFTERMARKET PARTS AND FOUND MULTIPLE PARTS. CAN NOT PERFORME CLOSED-CIRCUIT CURRENT DIAG TELL ALL AFTERMARKET PARTS ARE REMOVED. CLEARED FAULTS AND CHARGED THE BATTERY. Nothing stays on after car is shit down (not positive about wifi camera, will double check when I get car back). Any thoughts? No low battery power issues, just the occasional warning light in the dash.

The car senses if there is power draw when the car is off. Anything greater than 80mA will trigger the increased battery discharge alarm. You must have something plugged into one of those circuits.
Obd2 doesn't disable power... Start with removing that. I never had an issue with one tho. If that doesn't work.. Remove the other things one at a time until you stop seeing the message. Very annoying indeed!

Per the tech, one line is open on the obd2 so that may be the issue.

unless you have a garage where you have to roll back-up 2 inches from a wall or you have young children i don't see why anyone needs a backup camera.
Your custom WiFi probably has to stay alive all the time. |
