I will check batteries and look for wires on turbo. Changed batteries in 2010. upper 50s during the day this weekend, and upper 30's in the morning early. Southern Louisiana On I10.

 

check you connections at the turbo and look at aby and all connection and grounds on your fuse box and on the injection pump side of the engine there should be the ecm

 

OK, I did some research on the codes and saw it referred to checking connections. Some nice instructions on cummins site once you enter your EIN. I tried to look yesterday but it was cold and raining. I did let the RV idle for 1 hour and no luck with the check engine light going off. If I cannot see the the issue when checking the connections and wires, i will bring it into a shop. I will report what I find out.

 

I finally had a chance to look at the wiring to the turbo. The wire coatings were flaking off. I played with some wires and cranked it. No CEL. Took a spin and was able to get CEL but was off mor than on. Taking it in the shop next week. Will report back.

 

Sorry for the no show been busy the past several days or weeks not sure which. Well the flacking wire may be causeing a short or misread of ampreages to the ECU on your rig..

 

I tried to find a good diagram but was unsuccessful. Not sure what or where the flack wire is.

 

Wow, I brought my Rv to midsouth Cummings and they could not help me and referred me to another shop at a cost of 300 plus for failure to fix. Is this the norm? i already gave them the codes. I am not happy and will take time to review them on line.
