P288FShift Fork "B" Actuator Control Circuit Driver Current/Temperature Too High

P288F indicates that the transmission control module (TCM) has detected excessive current or temperature in the driver circuit for the shift fork 'B' actuator, which is part of an automated manual or dual-clutch transmission. The computer monitors the actuator's electrical driver and flags this code when the current draw or driver temperature exceeds safe limits, often due to a short, binding actuator, or a failing driver circuit.
