2022 F250 Electronic Locking Differential, Check Locking Differential issue
Error message

TCCM
Grounding point (1-3)
Body to frame grounding point
Hello ford enthusiast I’m in need of some help finding the issue to this problem I have above. I posted pictures to give you an insight of things I’ve already researched. My current theory is that my TCCM is defective and is failing to push 12V out on the Yellow wire. I’ve run numerous checks to see if there was a potential fault to ground and found none. Additionally, I have replaced the MSS (Mode selector switch) and do currently get voltage at the White-green on the TCCM however it seemed low. Which leads me to problem 2. Could the low voltage i believe was 10v prevent the TCCM from even pushing it out? What steps should I take? Purchase a TCCM? Let dealership identify fault? What’s the cost of something like this?
