Description: Side deck communication problem • An error code from the side deck is detected eight times in succession. No communication: there is no reply after 3 retries. Abnormal communication: a communication error (parity or checksum error) is detected five times in succession.
Causes: Poor contact in the connector terminals. Defective engine PCB. Defective main PCB. Defective side deck main PCB.
Remedy: Check the connection of connector CN9 on the main PCB and the connector CN3 on the side deck main PCB, and the continuity across the connector terminals. Repair or replace if necessary. Replace the engine PCB and check for correct operation. Replace the main PCB and check for correct operation. Replace the side deck main PCB and check for correct operation.
Code: C034
