Using Troubleshooting Blink Code Chart

Before attempting to troubleshoot your vehicle using Diagnostic Trouble Codes listed, ensure MIL system is working correctly. The light should illuminate when key is in RUN position, and engine is not running. This feature verifies that the lamp is in proper working order. If the light does not illuminate with vehicle key in RUN position and engine OFF, see your Technical Manual or your authorized John Deere dealer. Once the engine has started, the light should go off. If light stays on while engine is running, a current Diagnostic Trouble Code may be set or a problem may exist with the MIL electrical wiring.

The following is not a complete list of Diagnostic Trouble Codes which may display on your machine instrument panel when blink code function has been initiated. Contact your John Deere dealer when any other codes are displayed. If multiple codes are listed, always troubleshoot using the lowest first.
