2014 C250 *U0141*
Last week, my friend was using my car, and after turning it off, it wouldn’t crank when trying to start it again. Everything powered up, but it just wouldn't crank. Today, I finally scanned it and got a U0141 code, which I found refers to no communication with the BCM
I have two questions:
1. Where is the BCM located?
2. What steps should I try first to diagnose and fix the issue?
