Preliminary Instructions
• If the problem is in an electrical circuit board, disconnect then connect the board connectors again
before you replace the PCB.
• If the problem is a motor lock, check the mechanical load before you replace a motor or sensor.
• When a Level A or Level B SC occurs while the machine is in the SP mode, the SC number will not be
shown. If this occurs, check the SC number after the machine goes out from the SP mode. This does
not include Level B codes.
• Some SC codes contain more than one level (SC303-1, SC303-2, SC303-3, and others). Some SC
codes can show a “-1”, even if there is only one level.
The following abbreviations are used in these SC tables:
• (F) means "Front"
• (R) means "Rear"
