That's a great idea!
What you're doing by leaving the lights on, is taking off the surface
charge
of the battery, that the alternator puts on it. After a couple of hours,
the
parasitic drain from the volatile memory in the computer, even though
small.
Draws just enough, now that the battery is older, and The BCM (Body
Control
Module) sees that as an intrusion, as in stepping on the brake for an
example.
Thank you for that idea, I do diagnostics for a living, besides body work.
This will save me a diagnostic nightmare, if a case as this ever enters
the
shop.
Thank you again.
