Description
The vehicle trailer controller (VCTRAILER) ran a High Side Field-Effect Transistor (FET) functional test, but the voltage feedback was below the necessary threshold to confirm High Side FET functionality.
Condition
High Side FET functional test does not measure voltage greater than 2V, but a trailer is still detected based on open electrical load.
Clear Condition
The High Side FET functional test passes, or a trailer is no longer detected (no open electrical load).
Potential Impact
Trailer brakes may be unavailable or may not function as expected.
