Do you know what can cause this failure code 23? Transistor, diode, where are they located at?

That is one of the main reasons to never tow or push something with a fortklift. They have a tendancy to burn up electrical components. Most manufactures will not cover warranty on new trucks or warranty on parts if they know the truck was being used to tow or push something.

We call this the combo #3. Replace transistor, chopper control module and diode.
