The Voltage Output For Manual Trailer Brake Application From The Factory Installed Trailer Brake Controller On 2005-2006 F-super Duty Vehicles Is In Two Different Ranges, Based On Build Date. The Normal Output Voltage For A Full Manual Apply (manual Activator Lever Slid Fully To The Left, Gain Setting Of 10, Vehicle Not Moving) Is 1-3 Volts On Vehicles Built Before 3/23/05, And Is Greater Than 10 Volts On Vehicles Built After 3/23/05. Brake Pedal Based Output From The Controller Is The Same Regardless Of Build Date. Do Not Replace The Controller If It Is Providing Voltage Output In The Correct Range Based On Build Date. Refer To Section 206-10 Of The Workshop Manual For Further Information.
