Residual power

[ukrkoz]

I am referring to what several cars, I had and RAM I have, have - you turn system off, but you still have power for several minutes, so music still plays, phone stays connected.
Is there any way to turn this feature on in 2011 QX56?
Thank you

That's called Retained Accessory Power (RAP) and it's a BCM software function. You either have it or you don't, Nissan BCM's can be configured but they can't be reprogrammed (for security reasons). It doesn't look like your '11 QX has it. The only work around I can see is to change the Ignition signal for the radio from ignition to battery, but routed through a Hella timer relay driven by the ignition and gated by a standard relay driven by the driver's door switch. It won't leave anything else working (like the power outlets), but at least you'll have radio.

Thank you, appreciate response. Oh well. Kinda sucks, but not life necessary.

Sorry it wasn't better news.
