The cost of diagnosing the B14F1 FORD code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
The Upfitter Interface Module utilizes a Field Effect Transistor (FET) protective circuit strategy to protect the low and high side driver output circuits. Output loads (current levels) are monitored for excessive current (which is typically caused by a short circuit to ground) and are shut down (turns off the voltage or ground provided by the module) when a fault is detected.
A short to battery voltage occurring on either a low or high side driver output circuit may also result in a temporarily loss of operation in the output circuit (no voltage or ground will be applied to the output circuit) to protect the module against a potential over temperature condition.
A Field Effect Transistor (FET) is a type of transistor that the module uses to control and monitor current flow on module output circuits. The Field Effect Transistor (FET) protection strategy prevents damage from occurring to the module.
Whenever a FET is turned off because of a fault condition a Diagnostic Trouble Code (DTC) is set in the module which corresponds to the specific fault observed. The module resets the Field Effect Transistor (FET) protection and allows the circuit to function when the fault is corrected or the ignition is cycled off and then back on. The ignition should always be cycled from off to on after a fault is corrected to ensure that FET protection is reset.
