2014 bobcat 530 with doosan wont start throwing code M6507 ecu open circuit. I checked fuses all are good checked battery cables look good , I have power to key and does not seem to be a battery issue , I have 12.7 volts what else can I check
Sounds like a communication problem between the gateway controller, and the ecu. Look for worn wires in the engine harness. Also, Ground connections, on the battery ( the small connectors) have to be clean! I would start there.
