(5) ECM Description The service mode will provide a list of fault codes that an operator may communicate to a technician before traveling to the machine. Service Mode can be accessed using the key-switch method. Prior to starting the machine, quickly transition the ignition key from off to run (without going through start) three times to enter the Service Mode. If the display self-test is initiated, the ignition key transition was done too slowly. The LCD display is used to show the fault code, the Active or Logged status, and the ECM issuing the code.
