help! how to disable lock engine function?
komatsu pc200-8N1
5x engine oil flushing
pulled out injectors for flushing of the combustion chamber
reinstalled injectors
replaced monitor and engine controller
cleaned and checked all electrical socket and connectors
it shows error code D19JKZ and we’ve already checked all harness and fuses. they’re all okay.
the engine won’t start but it’s cranking, just wont continue
