Not just Ford, but all of them...including foreign
"Highly Integrated" plus the over all complexity of today's vehicles
are worrisome to me...technologist all my life, so speak with knowledge
on the matter
Buddy saved all her life...hubby laughs at this...just bought a C class
and he's keeping his Ford Ranger... Scared her so much when she 'tried'
to read the manual, about an inch thick. Hubby told her to take the
'free' class...and after her first session, came home to tell hubby
that there were over 100 computers in the lowest class MB...he continues
to laugh over this.
Don't blame the dealers, nor any mechanic too much...today's vehicles
require a computer background. Even at that, the 'right' computer
background...controls and systems background are my preferred. Process
control and real time even better
My mechanic is GREAT, but lacks that background, so I've become one
of his helpers... :B Mainly discussing to get to a divide and conquer
position. He is a Master ASE on engines, trannies, AC/cooling and brakes.
He is much more than that, but those are his certificates on the wall
Had a few PM discussions over 'Highly Integrated' trailer brake controllers
and those two still don't understand how any IBC and Sway Control
system can affect ABS on the TV. Even less on how it can affect the
engine and tranny
What am trying to get across is that when the OEM has control of EVERYTHING
on the vehicle...they get creative in pinching the penny
Meaning that a P2/P3 will have that design team working only on the
trailer brake control and the interface with the TV.
They CAN NOT touch the tranny computer, nor the ECU, etc. Maybe the
trailer brake controller that plugs into the TV's network port
Since there are so many inter-dependencies for the OP's vehicle, it
is almost impossible to diag it...add that in going bad...all of these
inter-dependencies has the chance (high) of taking other systems/components
down...they might still be just barely good for now...
Most of my auto electronics is no longer good enough to today's vehicles
and turn to my mechanic more and more. My hardware tools are still golden...
