There have been several reports where the PTO is inoperative after the PCM was flashed or replaced. When this happens, the PTO switch either flashes or stays on solid, but the PTO does not engage and the engine does not idle up.

If your vehicle has this condition, please return the vehicle to the dealer. Inform the dealer of the issue and refer them to STAR ON LINE case number S1818000027. The repair procedure involves connecting the dealer service tool (WiTech) and running a routine called PCM CONFIGURATION found in the PCM MISC FUNCTIONS menu..
