2009 Focus - Radio Controls Broke! Sign In

 I recently replaced an evaporator core on a 2009 Focus SE. The dashboard had to be removed for this. After putting everything back together, the radio controls are not working. The radio come on, and can be controlled with the steering wheel controls, but the controls on the actual radio itself do nothing.

With a scanner I pull a code U0255 - No Communication with FIDM (Front Integrated Display Module). This is the flat control panel that is the front of the radio. Using Mitchell's instructions on diagnosing this code the wires checked out and it said to replace the FIDM.

I tried another FIDM and get the same result. I'm not understanding how this thing could have broken in the first place. I barely touched it when I removed the dash.

Anyone else seen this?

Have you tested all your fuses using a test light with the key on?

Go back over your work and make sure you didn't forget to attach a ground somewhere, usually behind the kick panels.

The manual state the ground is in the center of the dash near the audio control module.

Yes, there are a couple ground wires behind the radio. They are hooked up. The front "plate" of the radio contains all buttons and knobs and is actually considered a separate module from the radio itself. There is one small connector going to this front piece. It has a power wire (good), a ground (good), and a couple data lines. My diagrams don't show where those data lines go so I am not able to check continuity on them.

Do you have the base system or the premium system?

If you have the premium system, the ground for that additional module is at the left end of the dash, near the bulkhead connector.

Yes, premium system. Is this is a ground that bolts up behind the left side kick panel trim piece? I have a good ground on the black-purple (I believe) wire at the small connector that plugs into the radio "face".

Yes, that is the one.

Thanks!

I already checked the black/violet wire at the radio and it showed a good ground. I will double check at the other end just to be sure.
