      E111 No serial comms!

      Description of error

      Display unit is unable to communicate with other system components.

      Solution

      Total CAN bus comms failure, usually caused by the CAN bus messages being swamped by errors. Slipring is the usual cause, water ingress or wear. Could also be a faulty sensor, identify by unplugging angle sensors / modules / encoder one by one until error disappears.
