What it means

Serial Communication Error Between MCU and CCU.

How to fix it

  1. Disconnect power and unplug unit. Check wire harness connections to the motor, Motor Control Unit (MCU), and Central Control Unit (CCU). Check the drive system for any worm or failed components and reconnect power and plug unit in. Verify CCU is working by performing diagnostic test or any cycle. Check MCU by looking for operations of the drive motor and check drive motor for powered rotations. Make sure the serial harness at the MCU is not mounted upside down. The wires should be to the left when facing the MCU connectors. Replace failed component.
