On Komatsu Forklifts with K21 or K25 engines older than 2007, unfortunately there are only two ways to get the codes out. The pedal dance or the Hitachi Handset. 2007 & newer the EPA mandated OBDC II Code in the ECM software so you can pulll codes with a generic OBDC II Code Reader. Komatsu also offers laptop or Tablet based software to pull codes.
