Driver Control Fault Service Required

[Marcoslps]

I have a question. I made some changes yesterday to my forscan because for some reason I dont have high beams. When I started the truck it now says Driver control fault service required.

I believe this started after trying the headlamp recalibration or ride height recalibration.

Any tips?

What did you do that caused no high beams? Change head lights?

If you saved your as built before making changes in forscan you should be able to load that back in.

Why did you have to make these changes? Did you change lights? Lift truck? Need to go back farther then forscan changes. What made these changes need to happen? Go back to when was working and what did you do? No high beams i would assume you changed lights or wiring. What caused no high beams?

I found the issue. I mistakenly tried to recalibrate ride height in the VDM. So now its looking for ride height sensors and throwing the code C1124:55-2F. I have loaded the factory as built, and write it. Attempted to reset the VDM module but the code doesnt go away. Pictures attached.
