The most common cause for this Ford F-350 B0259 type of failure is due to liquids spilled on the upshift/downshift switch. Open or shorted electrical wiring, damaged, corroded, or disconnected wiring or connectors are also a viable possibility.
A sure sign of this is smoke or steam being emitted from underneath the hood. The ignition timing could be set incorrectly and will require adjustment. If, when looking under the hood, you notice that the drive belts appear loose, they need to be tightened or completely replaced. If there is a noticeable pool of fluid underneath the car, this could be a sign of the cylinder head gasket failing. That will be confirmed in the form of billowing smoke being blown from the exhaust system. Parts or components should not be replaced with reference to only a Ford F-350 B0259 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
A repair technician can do so once repairs have been made.
The OBD II can automatically turn it off when it fails to detect the problem after several diagnostic cycles.
