My name is ***** ***** I will assist you.

That code is related to lighting and shouldn't shut the truck down.

Are the fluid levels good? Do you still have a green light on the fuel filter setup?

I'll verify the codes online as soon as I return to the shop. Currently in the field and on way back.

I just had all filters replaced, including the fuel filter, and the fluid levels are also good

I apologize for not getting back sooner. I couldn't get online. Yahoo was hacked and my account passwords were changed, then I use another yahoo account to verify this account and I had to fight all morning to get my passwords fixed.

Trailer brake lamps below normal or open circuit. Fuse 23 or relay 7 at the SAM cab might be defective. Test and see if they are missing or damaged. If not, start checking the pigtail and the trailer.

The one is a short in the left turn signal.

Both of these can be related. Check the turn signals on the trailer and then check the relays in the fuse box on the firewall. That relay number 7 gives a bunch of issues and we swap them a lot because of the different codes it always provides.
