Just installed an oem brake controller. Enabled with forscan. With no trailer I can adjust gain but when I press the slider nothing appears. I thought it would say no trailer connected or something. Is my unit bad or is this how it’s supposed to be until a trailer is connected?

 

Need more details on your truck

 

You may have to take it to a dealer to have it properly programmed. Even disconnected, it should read no trailer when actuated.

 

There have been problems with off brand controllers. Is the one you bought a genuine Ford controller?

 

It’s off brand. I ordered a different brand and am sending this one back. If that doesn’t work I’ll cough up the coin for a Ford product.

thank you all

 

get the OEM , the China copies aren’t worth the money, I had the same issue twice.

 

replaced with a new unit. All is working as it should now.

 

Yes, she is! Very! Time for a spanking...

Sorry, couldn't resist.

 

Uh, has the forum direction changed course?
