Looking for a way to turn off accessories

lolbrother · 03-05-2021, 03:41 PM

I have a dash camera in my 12v socket, and a usb charger in the usb slot. Even when the car is off and locked, the camera and charger stay on. Any way I can code it to where when I lock the doors from the outside it turns off?

It turns off automatically after 5-10 minutes.

Yes it does, but I want to know if it is possible to shorten that time so it turns off right away?

I *think* this is it:
FEM -> 3020 TcMaster-> TCM_TIME_KL30B_OFF

Values are hex, in minutes. Default appears to be 12 minutes, with options for 2 minutes and 30 minutes. If you use esys or bimmercode, you should be able to inject a custom value.

I think TCM_TIME_KLR_OFF is related as well. Default value for that appears to be 8 minutes.

Effectively, these are settings that tell the FEM when to shut off certain power to certain terminals.

No guarantees I've got it right - this is just my assumption based on the fact that accessory power is off of terminal 30, and there is related coding on TcMaster that controls when to shut off power to the radio (terminal 15) such as when opening the door, etc.
