Driving down the road today under normal conditions and running empty (no trailer) my check engine light came on. After checking I got 4 codes, P0882 )Trans relay circuit low), P2769 (TC), P0148 (RP) and P2149 (Fuel injection group 2 circuit). Any ideas what to check for? I cleared them out and as soon as I started the truck, the P0882 came back. Truck is driving normal and acting normal. Suggestions anyone?

 

Well with all of the aftermarket things plugged in it could be lots of things. I don't remember which fuses the Juice uses to tap into, but I would make sure all of the Juice taps and the fuses they are on are good. After that checks all connections/connectors.
