Hi all,

I've owned my 2011 F150 supercrew lariat for 3 years now. The head unit went after 18 months so I decided to replace with the pioneer dmh-1500nex with the data link maestro rr interface module so I could keep all the controls on steering wheel.

It worked great for 3 months then the head unit stopped turning on. I've been testing trying to diagnose issue with no luck... I even purchased a second head unit and interface module to test thinking one of those went, but the new ones don't turn on either.

All fuses have been checked, wires checked.. Can't find the source.

Any ideas?

 

Do you have power your 12+ constant and 12+ switched leads? How is ground looking?

 

Where is your remote turn on wire? If you "jump" power from the main 12v to the remote turn on, does it then turn on?
