Below is a photo of the current codes for the most part they indicate a open ground /short. Not sure what steps to take next. The airbag light is not activated on the dash nor abs. Truck seems to operate as usual. Just did a cold start at 25 degrees and there were no issues. Was tough to start the other day after sitting for a week seems to be loosing power if left to rest.
Just so we are clear, what manufacturer year vehicle were these codes pulled from? It does make a difference when selecting pinpoint tests for auxiliary systems.
I am not seeing those DTC's in the manual. I have been looking and come close to them, but not specifically those DTC's. The sections for the trucks with a VSM instead of a GEM are a lot more convoluted in my opinion when looking at the manual.
I would encourage you to select the DTC's within FSL and/or search for them on the interwebs in order to narrow a section of the vehicle to look at.
If you suspect a ground is bad or loose, check the major grounds like the 2 on the block, one above the PCM on the firewall, one near the hydroboost on the fender, etc... I apologize I could not be of more specific help to you.
My 02 had a loose ground on the front of the block down low where the fuel lines start to come up. It is hard to see/tighten, but it was oil covered and hand tight. I was not having any issues, just passing it along.
I was able to find U1059 in the Instrument Cluster section of the manual. Attached is a PDF of that entire section of the manual. You will need to perform Pinpoint Tests F.
The rest of the codes are found under Multifunction Electronic Control Modules. Follow the document's guidance on the pinpoint tests to perform for each code accordingly.
