found my mcm to be bad
ive gone through all normal procedures in DL to save old MCM info to server
plug new mcm in and go to program and says new mcm not connected. why?
i have full DL access
lets me update and program cpc and acm but shows grayed out mcm missing
truck has a new harness - not wiring issue
i can plug old mcm back in and it will read it.
any ideas?
