F-body is different --> "special"
Lol...:hihi:...all other car models are different than F-body... :gossip:
F-body BCM is not connected to the Class 2 bus, and has no bus style connection to any other module...
(this makes it a PITA to diagnose BCM problems, as you have discovered)
See attached diagrams (All Else.zip and PCM.zip) for 2001/2002 F-body.
Even the high end Genisys/Snap-On scantools do not see the BCM when connected to the F-body DLC...
By contrast, Y-body has just about everything on the Class 2 bus, see attached... :doh2::doh2::doh2: ...it's a wonder that the tunetool can get bus bandwidth.
So Paul was correct about the BCM being on the Class 2 bus, for everything except F-body... :)
