Doosan (& Daewoo) G25E-7:
Pulling Codes 2022 G25E-7

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.

Figured I would post an update. I was able to get he MIL light to blink out 3 digit codes by doing the "Pedal Maneuver"

The Pedal Maneuver procedure is below if anyone else needs the information.

"Displaying Fault Codes (DFC)
from SECM Memory
To enter code display mode you must turn OFF the
ignition key. Now turn ON the key but do not start
the engine. As soon as you turn the key to the ON
position you must cycle the foot pedal by depressing
it to the floor and then fully releasing the pedal
(pedal maneuver). You must fully cycle the foot
pedal three (3) times within five (5) seconds to
enable the display codes feature of the SECM.
Simply turn the key OFF to exit display mode. The
code list will continue to repeat until the key is
turned OFF. "
