Communication with the Power Take-Off (PTO) Control Module has been lost on the vehicle network. This module manages auxiliary equipment powered by the engine, such as hydraulic pumps, generators, or other work equipment.
The most common cause of U0117 (Lost Communication With PTO Control Module) is: Damaged wiring harness or corroded connectors to PTO module
Typical repair costs for U0117 range from $150 to $1,000, depending on the vehicle, location, and whether you do it yourself or go to a shop.
PTO equipment will not function, but vehicle can be driven normally. This primarily affects work capability rather than basic vehicle safety or operation.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0117 to identify the root cause.
