Diagnostic Trouble CodesWhen either a Service Alert or Information indicator is displayed it is suggested the tractor be placed in park or engine shut off. Restart the engine to verify if the active Diagnostic Trouble Code reappears before contacting your John Deere dealer. Sometimes, the code can be corrected by resetting the communication messages when tractor is restarted. Some Service Alerts and Information indicators can be acknowledged and display cleared by pressing the select switch on the CommandCenter. The display will return to a normal mode allowing tractor function to continue. However, diagnostic trouble code may reappear at a later date if condition still exists. For an explanation of STOP, Service Alert, Information Indicators and Diagnostics Trouble Codes refer to section 15 in this document. |
