Error Message F-01

I have a Unicarrier forklift M#MCP1F2A25LV S# CP1F2-9W2945 with 4800 hours. This forklift worked fine Friday and Monday it won't turn over. I can bypass the start circuit and it will start and run, but won't allow hydraulics or drive. A troubleshooting chart or suggestions would be greatly appreciated. Thanks

I've checked all the fuses, connections at battery, and vcm.

Error code F-01. VCM Memory Check. Condition- EEPROM check sum, Controller type not matched. Action- Control module stops operation (only executes CAN communications)

I will update if I find any trouble shootimg tree. Can only find the code description right now.

Id check all the grounds for clean connection. The one by the vcm and the one on Lh side as well. Also check power and grounds to your vcm connectors. But sounds like a VCM issue. Could swap in a known good vcm if you have a similar 1F2 truck around.

Fact of the week
In March 2002, identical twins in Finland died on the same day in similar accidents within hours of each other. A 70-year-old man was killed by a truck while cycling; hours later, his twin brother was killed by a truck on the same road, about a mile away, before the family had been informed of the first accident.
