    Welcome to the HEF! Good the have you. Tap the brakes for a second. It’s Friday afternoon before a three day weekend. We can’t just dive into this. Let’s sit down and think this through. Tell us a little about yourself and your tractor. Head over to the new member area for a proper introduction. We can chat this tractor problem out later. I’ve got problems, too. A TCU code isn’t one of them. What do you use your tractor for?

    Thanks for your response and tour welcoming. I work as a maintenance coordinator in a company specializing construction in Morocco. The Tractor is used for pushing rocks.

    Welcome to HEF younessBT1990 ! A machine serial number would help out tremendously.

    That is not the machine's serial number. The product identification number (serial number) is located on the right-hand side of the crawler frame below the operators station (basically under the right entry door step). Depending on the age of the machine it will be either a 13 digit or a 17 digit serial number (which will include the model 850J). 524089.04 - Left hydrostatic pressure sensor (B6) circuit is open or short to ground.

    Hii mg2361 Amd do you know where exactly this sensor is located ?

    Mounted on the top of the left drive motor. Make sure the wiring is OK before replacing an expensive sensor.

    Hiii mg2361, Thank you so much for your time and your help, and as you recommended we checked the wiring and the fault is gone.
