Temp gauge has been acting up for the last few months but didn’t actually have any issues with the machines temp when I checked so I have continued to run it, ignoring the temp alarm. Today, while running the machine, the electric parking parking sign came up on the dash without me activating it and the machine would stop driving, then showed the 4 codes I listed earlier. I shut the machine off for about 20min, checked wiring connections and fluids with no issues found, started it back up, ran for 5min with no issues then it did the same thing. Shut it off and restarted multiple times with the same response.

Sorry to hear you're having these troubles with this equipment. These fault codes indicate loss of datalink communication with the machines electronic control module. Be sure to first check all your fuses and relays for any failed that might cause a loss of power to the control module. This could because by a loss of power or ground but also a potential wiring harness problem with a short or open circuit, as well as a possible problem with the control module itself or a software programming related issue that would require dealer level programming with John Deere service advisor connected at the dealer level.

F9C4 is CAN messages not being received by the ECM

F9A3 is monitor fails to receive power configuration message.

Have the control module checked at the dealer for a possible faulty control module if no power or ground iissues are found as well as any software related glitches if they attempt to reprogram and update the software.

I hope you find this information helpful. Reply back with the results of these checks if any further advice is needed. It's a pleasure to help anyway I can.
