Ah, you must think about the later models with the DPF unit under the hood?

This is the old one installed on top of the counterweight with a Fan/Dieselpump/Glowplug system and a manual cleansing cycle.

Been able to connect to it before and check codes and reset it.

But now the fault is that the forklift can´t communicate with it and sets the fault code D160, and you are unable to regenerate the sootfilter.

Hope this cleared it out! :)
