That's a network error: Lost Communication With Body Control Module
With what software or scanner did you read the code?
I read it from the dashboard directly by scrolling through the test mode
It was clear, then the fault happened long enough to bring the ecu light on briefly, and then the code was stored
The alternator light came one once apparently for 30s or so , but i wasnt driving it at the time to see.
