Check for applicable trouble codes. To check codes yourself, at the least you need an obd2 code reader for generic as well as manufacturer specific codes. I'd have to check voltage and ground circuits at the instrument cluster. Go from there.

Sorry your question is too vague. I see nothing labeled, "main cab ground". There are many ground circuits.
