4.3.3 SC CODE DESCRIPTIONS
Important
•
If a problem concerns a circuit board, disconnect and reconnect the connectors
and then test the machine. Often a loose or disconnected harness is the cause
of the problem. Always do this before you decide to replace the PCB.
•
If a motor lock error occurs, check the mechanical load before you decide to
replace the motor or sensors.
•
When a Level “A” or “B” SC occurs while in an SP mode, the machine cannot
display the SC number. If this occurs, check the SC number after leaving the SP
mode.
•
The machine reboots automatically when the machine issues a Level “D” SC
code. This is done for Level “D” SC codes only. ( 4.3.2)
