If I'm reading his post correctly, his problem is that after the repair work was done and the codes were cleared the CEL is still illuminated and they can't seem to figure out why.

if the truck cab controller is a paccar product (mack, peterbilt, kenworth, etc) .. then they are well known for this issue where there are no engine codes, but the CEL light / dash controller has ghost errors in them. those things are flaky as hell. It is mentioned a lot on this forum in the past. here is one reference + solution.

light finally went out while the truck was shut off for the night.
was able to use insite and found the following codes:
0286 count 2 sae j1939 multiplexing configuration error-out of calibration
0285 count 4 sae j1939 multiplexing pgn timeout error-abnormal update rate
6339 count 2 fuel level 1-abnormal update rate
2198 count 2 vgt actuator driver circuit-root cause not known
0197 count 1 coolant level-data valid but below normal operating range-moderately severe level
5868 count 1 atertreatment 1 scr feedback control status-mechanical system not responding or out of adjustment

overall, it points towards some part of the (j1939) canbus #2 not functioning properly, as all of those faults, fuel sensor, vgt, and after-treatment components are all connected to that one.

were those seen only in the dash?, and not to be found when ising Insite to see the codes? - or are they in the engine fault code history too?

maybe want to read this post too.
