Komatsu Reach Error E-10

I have a problem with an old Komatsu reach truck throwing up a fault code E-10. Unfortunately there is no plate on the truck with serial model etc, the customer thinks its an FB15 or FBM 15 something like that.

The system on it seems like the one they use on Nisaan electric trucks. A large gold cased card that sits on top of the IGBT's. There is no drive just lift works.

Any body have any fault codes that might tally with E-10 off a komatsu or even a Nissan perhaps, just to give me some idea:)

Fact of the week
Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
