The local NAPA has been asking me for a while to take a look into an issue with the fuel Guage reading/not working issue on an 06 Kodiak 4500. The truck is the short cab version that has a dump bed installed but one of the fuel tanks has been deleted apparently to make space for the hydraulic reservoir. I have a "screen shot" here with some EFI Live Data on something similar. F0301 25 Gallon Capacity, F0302 25 Gallon Capacity, F0303 40 Gallon Combined Capacity. I stopped out around 4 O clock and read the truck to get the Data/OS info. Unfortunately i think they cleared the codes where the truck has been sitting for a few days. Also this vehicle is equipped with the Allison Transmission which uses a separate TCM that Reads/Writes separate from the P59 PCM.
