Hello. I will be trying to troubleshoot a new to me forklift. It is a 2022 Doosan G25E-7. It supposedly overheats and shuts off. My gut says that there will be codes stored and there is more to the issues this machine is having. How can I go about retrieving the codes off this machine? This is a newer machine than I am used to and want to try and be ready when I see it.

Are codes retrieved by completing the "Pedal Maneuver" and watching blink codes on the dash?

Or by jumping pins 1 and 4 in the DLC connector and watching blink codes?

Alternatively can the codes be retrieved with a laptop, communications adapter and the appropriate software? Anyone know what software and hardware is needed to connect to the forklift?

Thanks for any information you can provide.
