B1925 is an OBD-II body code for a Ford vehicle, as all B1xxx codes are manufacturer specific. It pertains to a vehicle’s electrical circuit for the battery and the passenger side air bag.

While inspecting, they will ensure all grounds are cleaned and in working condition.

Mister Ron was very nice and took time out to explain any concerns I might have about my car. He also made sure he communicated with me when he was on his way, once he was outside, and when we was done working on my car. I appreciate that considering I have a newborn that I had to look after.
