I'm curious to know if you would ever need to add solder to the MCU?  How do you determine which area is lacking a solid connection?

Sometimes you can tell visually or by how snug the edge connector feels. You may note be able to tell and may need to add solder to both the CCU and MCU IF you're really dealing with a communications error.

 

The question you need to answer during your diagnosis is this: Am I really just dealing with an intermittent communications error or a bad MCU?  

 

Keep in mind that, depending on how it fails, a bad MCU can also cause the CCU to throw and F11 error code. The MCU may not be sending a handshake signal back to the CCU so the CCU algorithm would flag that as an F11 error code.
