In the USA, a hyster J series truck that has a serial number series that starts with "a416" would be a z (ac controller powered), not an xm. I know the weight class are metric -vs- US pounds but unless we know the correct model and serial, it is almost impossible to be sure of what those codes refer to.
if it is an AC powered truck (assuming the serial number is correct and model number wrong), the code 52 refers to "traction or pump motor speed sensor error". check the wires to the motor encoder or the encoder itself.
