B14F0 Ford Code - High Side Driver 1
Quick Answer
The Upfitter Interface Module utilizes a Field Effect Transistor (FET) protective circuit strategy to protect the low and high side driver output circuits. Common causes include Faulty Upfitter Interface Module, Upfitter Interface Module harness is open or shorted, Upfitter Interface Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B14F0 Ford Description
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.
What are the Possible Causes of the DTC B14F0 Ford?
- Faulty Upfitter Interface Module
- Upfitter Interface Module harness is open or shorted
- Upfitter Interface Module circuit poor electrical connection
