Trunk lid question
UPDATE:
Seems I have a new problem.
The power trunk feature does not work at all.
(Latch and Lock work as expected, from trunk handle, from door switch, and from remote)
Will not power open or power close. (No noise from motor at all, no motion at all)
Does the same thing from the handle, remote or drivers door switch.
The power latch cycles, so you can "pop" it and then hand open and hand close.
All rear taillights work fine. (Checked license plat light)
No dash error.
I think the red trunk buttons are not lit (Will check tomorrow). (Red Lights are NOT lit)
Guessing it is either a popped fuse, or maybe a different wire in the trunk bundle.
(Checked wire bundle and checked fuse. Both good)
I fixed the famous broken brown wire a coupe of years ago, and at that time none of the others looked bad, and I rewrapped the bundle to move the stress from that point.
(Fix looks good, unwrapped and no new signs of stress or rubbing)
Also wondering of it was a wire, why the remote or the drivers door switch would not work? (
Maybe a wire frayed and shorted taking out the fuse? (Nope and Nope)
Thoughts anyone? (HELP!)
All New Below

Kind of thinking it has to be the controller, the position sensor, or a secondary trunk open/closed switch.
Does anyone know if the trunk has a second switch that the controller may reed as a safety, or is the position sensor the only one?
Anyone have a controller or a position sensor fail?
Anyone have a diagnostic service sheet on the trunk opening system?

With your VIN I would love to know why you think you have a N111 module???

My trunk lid opens manually regardless of interior lock engaged.
And the below attached scan generally. Last year engine light turned on and fan at full speed. CAN issues galore. Scanner skipping over transmission. My attempts at a fix replaced front SAM, tested ECU, EIS with no effect. Replaced IC last week and new code litany rendered. Since the trunk lid has explicit problems, starting there seems reasonable.
