Check the wire harness that goes to all your connectors on the Motor, MCU, and CCU. I have seen a loose wire connector do this F06 error.

If all checks ok, then its a faulty CCU that needs to be replaced. Here is the part.

I had this error and engineer said the meaning of the codes on the web are wrong as they don't like to disclose their real code meanings for pure protectionism reasons. F06 on IWD7145 is a burnt out door interlock IDC error. He replaced the part number C00085194 (replacement door interlock) and microritardator part number 085194 and it works ok now.

Before you replace the control panel use a tester on the cable to check continuity .. if the cable is faulty you will get this fault

POSSIBLE COMMUNICATION PROBLEM BETWEEN MAIN AND MOTOR CONTROLLER
