Is Weak Pulsing on Trailer Brake Controller Output Pin Normal
Published 04/05/2019
Question:
2013 Ford F-350. 2015 5th wheel. Disc brakes installed 2017. I have truck set to EOH brakes. About 2 months ago, the titan actuator started pulsing. Actuator works normally when brake pedal pushed or when Breakaway is pulled. Put a test light on the truck plug. Noticed a weak regular pulsing signal on the brake pin. I suspect a problem with the truck but Ford dealer says everything is ok and weak pulse in the brake pin in normal. Appreciate advice.

Expert Reply:
The weak pulsing you are seeing is normal on the output pin of the connector. That pulse is actually your brake controller constantly testing to see if a trailer is connected. Basically it's looking for a low amperage draw when it applies the voltage which tells the controller it's actually connected to a trailer and to start operating the trailer brakes. Since the brakes are working like they should you are totally fine!
