Manual Extract:
Failure code [56] (Disconnection or short circuit with chassis  ground in caution buzzer relay system) is displayed
– This troubleshooting is carried out when there is still an abnormality, so when disconnecting the connector and inserting the T-adapter, or when removing the T-adapter and returning the connector to its original position, if the error code is no longer displayed on the monitor display, the problem has been removed.
– Before carrying out troubleshooting, check that all the related connectors are properly inserted.
– When the joystick steering lever is not being used, leave it at the neutral position.
– Always connect any disconnected connectors before going on to the next step.
