John Deere Fault Codes List - 1
John Deere Listing of Diagnostic Trouble Codes (DTCs)
NOTE: Not all of these codes are used in all engine applications.
NOTE: If the corrective actions below do not solve the engine fault, contact your servicing dealer.
The SPN and FMI codes in the table below are not intended to be paired from left to right. There are several possible combinations of SPN and FMI codes. To use the table below, first write down the SPN and FMI codes you received from the engine diagnostic gauge. Locate each SPN in the first column and its associated definition to the right in the second column. In the same way, locate the FMI in the forth column and its associated definition to the right in the fifth column.
