System Description
WARNING: This page is about a different car, the 2016 Nissan Rogue. However, it is still accessible from the selected car via links, so may be relevant.
A smart Field-Effect Transistor (FET) is a transistor used to monitor and control current flow on module outputs. The IPDM E/R uses a smart FET protection strategy to prevent module damage in the event of excessive current flow. The smart FET protection strategy monitors its outputs for excessive current, and when a fault occurs, shuts down the output and records a DTC.
