Hyster H70FT:
fault codes and no start

I just purchased a unit from a remote location. Unit was suppose to run and operate. Unit will not start and has these codes. ECU522739-5 #6, VSM2023-12 #1, VSM524263-1 #3 Vehicle system Mngr HW4430040, SW P 5.67. This is my first newer hyster 2005. Unit does crank over, has no spark from the coil.
What can anyone tell me about all of this.

ECU522739-5 is open circuit in Heated Oxygen Sensor
possible cause:
Heater supply/drive open circuit
sensor failure
functional failure in controller

VSM524263-1 is Uncommanded Power Down
possible cause:
TCU program corrupted or TCU application file mismatch
functional failure in controller

VSM2023-12 is canbus error with display
possible causes for this error are:
termination resistors open circuit
open/intermittent circuit on can HI, can LO
can HI and can LO shorted together
open circuit on power/ground to can connected devices
STG on can HI
STS/STB on can LO
can connected device failure

Check all wiring and connectors and make sure they are in good order, fully plugged in, make sure no broken wires, corroded connections, all ground connections are good, and check all fuses to make sure none are blown.

If you find no issues there then try clearing out the codes, generally if you turn off the key (for no less than 30 seconds) the codes should clear, if not then you will have to go into the DSC and check truck serial number and make sure it matches the dataplate. A software update may be required.
Generally these type errors are caused by a connection issue but ultimately could be a component failure.
A call to your local hyster dealer to get a qualified tech to look at this may be required.

How can you move a batch of palletised goods in half the time? It’s simple: carry the pallet loads two at a time. That’s the idea behind the new platform double pallet handler range from Cat® Lift Trucks.
Safety in operations is gaining increasing attention these days. Potential risks associated specifically with warehouses and production areas are becoming especially apparent at times when goods handling is extremely busy. However, the growing portfolio of safety solutions from Linde Material Handling (MH) can assist.

Fact of the week

John Lennon had terrible eyesight and was very self-conscious about it. Early in his career, he would not wear his glasses during performances. In the end, John's 'granny glasses' became one of his most iconic trademarks. His last pair, worn on that tragic day in 1980, are kept at 'The Beatles Story' exhibit in Liverpool, insured for over £1 million.
