A951_O: Memory Card Data Write Failure
On the VSODC, this fault would be displayed on the seven-segment LED as d1.
The Drive LED's will not report non compressor or non drive related faults.
The VSODC is unable to write to the memory card. This could be a defective memory card or loose memory card within the socket. Remove the VSODC and inspect the back of the control where the memory card is inserted to see if any loose solder joints are present. If not, reinstall and reinsert the memory card to see if the fault goes away.
The memory card may also be defective. Replace the memory card.
