Greetings all....I am needing some help with a Hyster H60FT S/N L177V03711G

I have a wrench light on and a code of 524240-3. I know the code is for the rear washer driver. What I don't know is how to diagnose that this driver is in fact the issue, and where to find it! The truck operates normally...no issues other than the code and wrench light.

Also, do these Hyster units have an OBD II port on them for diagnostics?

Any help would be greatly appreciated.
