      HINT:

      1. Electrical noise from radio waves generated by optional components or the wiring for those components may affect MOST communication.
         
      2. This DTC may be stored when a MOST communication error occurs due to electrical noise.
         

1. Remove optional components (including associated wiring).
   

   NOTICE:

   Do not remove optional components or associated wiring without the permission of the customer.

1. Clear the DTCs (Click here).
   

1. Recheck for DTCs and check if the same DTC is output again (Click here).
   

   OK:

   No DTCs are output.
   

1. Disconnect the multi-display controller sub-assembly connector.
