Roof Controller odd issue

  Having a very weird issue with my RFC v2 controller.

  Every so often, while I am driving, I get a warning that my roof has malfunctioned. The error immediately goes away and the roof continues to operate as expected.

  I have had it pop up twice in a single drive. I have no idea if a bump triggers it or what, but it seems to have started happening more frequently as it has gotten hotter outside.

  I have had my RFC installed for 4 months.

  Anyone seen this before or have any tips? I don't want to leave it be and find out that my RFC is slowly damaging my car.

  this error message will show up if communication over the CAN bus was lost for a short period of time for some reason. It could be due to bad contacts. It is nothing harmful to the car, just a warning of the bad connection.

  RFC module does not have any connection with mechanics, just handling button activation and pass-through CAN data. The instrument cluster expects a response from the roof controller every 10 ms, if one message is missing, it will report a malfunction. It will clear up if communication is restored.

  @mx5things Thank you for the reply. As soon as I am able to I will open the flap back up and check my connections.
