im trying to read 2013 Ford Focus ST 2.0 and it doesnt want to.
can anybody tell me what the hell does this mean:
Controller Unlocker: x7F Service Not Supported in Active Session
TC-1767A ECM
GMBN1SA.H32 CCF
and how can i read this ecu?
thanks in advance
Pretty sure I got this on a 2012 F150 EcoBoost when I tried to read with the engine running. Try reading it key on engine off and see if it works any better.
This ECU is tuned by a Cobb Accessport (The CCF portion = Cobb Custom Features).Originally Posted by GeorgeGG
They "lock" the ECU preventing a normal read. You will need to uninstall the Accessport from the vehicle before reading.
If its not broke, just give it time.
Just ran into This on a 10 model Ford 5.4 truck…
