    Cat 279C2 Drive Problem

    Ok. The joystick calibration goes through successfully. The machine is not able to be used the way it is. If you try to drive it, it will start driving and will lock up especially if you stroke the joystick too much. It will move for a little bit if you barely stroke the joystick. Turning seems...

    I believe it was called the fed rev solenoids.

    Cat 279C2 Drive Problem

    I erased them yesterday and ran the machine. Could not get a code until I tried to calibrate solenoids. Then it came with the code pictured below.

    Cat 279C2 Drive Problem

    Yes sir. While I had the ECM plugs off I went ahead and checked both sides. While trying to perform a solenoid calibration is when it will throw the code. There are no active codes but after trying calibration it fails to calibrate and will be in stored codes. Attached are pics of codes. I did...

    Cat 279C2 Drive Problem

    Sorry for the delay but I looked at machine today. I checked everything you sent over and everything checked out. On the form you sent it showed homing out 42 and 43 with jumper in but the schematic shows 41 and 42. Maybe just a misprint. See below.

    Cat 279C2 Drive Problem

    Thank you so much for your time. I will go through both troubleshooting links above. The mechanic that came out works for Cat and I would assume it was Cat ET software but could not say for certain. Have you ever saw one that will all of sudden swap the forward and reverse direction using...

    Cat 279C2 Drive Problem

    Before the mechanic came we did not have any active codes until he performed the diagnostic test. After test 2685-8 was active. We ohmed out the 4 wires to the ECM and checked good. I have had a few 1706-5 in the stored codes but never active.

    Cat 279C2 Drive Problem

    That makes no sense. There is no calibration for those sensors. Do you mean he ran a "diagnostic test".? It must have been a diagnostic test. The machine had to be up in the air. It kicked out the test.

    Cat 279C2 Drive Problem

    I have a Cat 279C2 serial number AT0279CTKWB00583R that has a drive problem. If you drive forward slowly it will move forward. If you stroke the joystick more it locks up the left track. If you slowly go in reverse it will ease backward but will lock up the right motor with more stroke of the...
