Nothing

Hello, if the codes come right back, they are "active" hard faults that are likely related to component failure or electrical short / ground issue. I'm seeing concerns related to throttle position, fuel pump driver, and glow plug? This is a Diesel? You didn't share any information about what engine, how many miles, and so on.
