Also, can’t find a switch for brake.I’ve checked seat switch, but have only found 1 switch that controls rto. I replaced the pro switch. I checked and cleaned relays. I guess it’s in the circuit board. Looks difficult to test. Thanks for your help
Thanks, I willI believe TM2023 is the Deere technical service manual for the X485. Deere typically have very detailed wiring diagram and diagnostic instructions. My suggestion is to invest in the manual.
