She is an automotive instructor assistant at a local tech. I understand too, without Case software, troubleshooting is like taking the long way around. In addition to troubleshooting the problem, it helps me learn how the dozer operates. Turn the key on, safety levers down, and at the 9 pin deutsch connector check power from pin A and C. With only the travel controller plugged in (dash display and left joystick unplugged). With only the dash display plugged in (travel controller and left joystick unplugged). (dash and travel controller unplugged) Turn the key on, safety levers down, and at the 9 pin deutsch connector check power from pin A and C. With the travel controller unplugged, the joystick and dash display were both still plugged in and powered up (safety levers down) with the dash display unplugged, the joystick and travel controller were both still plugged in and powered up (safety levers down)ģ. With the joystick unplugged, the dash and travel controller were both still plugged in and powered up, (safety levers down)Ģ. The voltage readings seem a little odd to me, I just want to make sure you checked it right.ġ. With the joystick unplugged did the dash display still say "NO CAN" ? When the ignition is turn on, do the gauges on the dash display function? Does the speed needle come up to 60% speed? As long as you don't mind these tests, I don't mind helping. I know these checks are getting long, but I don't like to condemn an expensive part without all the proper checks. All of your other checks appear to be good. The travel controller connector is easy to take apart, and you can easily back probe power to the wires as needed, with the controller plugged in. (I suggest a 1amp fuse because if I remember right, the controller takes a 1amp fuse in the fuse box) If you don't have a fuse holder, just use spade connectors to a 1amp atc fuse. I like to use a fuse holder, in case something goes wrong you pop a fuse instead of melting wires. If you do not have power at all the wires with the levers down, then jump power to them and try it. Sorry, I forgot to tell you be in neutral and to put the safety levers down when checking the travel controller power wires. Your travel controller is not getting power at all the pins. The 2050M features easy access and grouped service points - and the enhanced CASE SiteWatch™ telematics provides insight into machine performance, maintenance intervals and more - allowing you to stay ahead of service and achieve optimal uptime.You have proper CAN ohms at all the connectors (connector side is what we are concerned about) This tells us that the CAN harness should be good. And an “isolated” design further reduces cab vibration and provides a smoother ride. A true positive-pressure cab with advanced sealing helps keep out dirt, dust and noise - creating a working environment with one of the industry’s lowest sound ratings. Additional fingertip controls for Blade Shake (shedding material off the blade) and Fine Grading (cutting blade speed by 40 percent for greater control) further improve performance.ĬASE M Series dozers provide some of the industry’s best sight lines down to the blade, the tracks and the worksite with excellent visibility and lots of glass from floor to ceiling. An advanced load monitoring system automatically reduces track speed (increasing torque) with a heavier load on the blade, and increases track speed (reducing torque) with a lighter load on the blade, ensuring that the machine is working at optimal power and efficiency at all times. The 2050M allows operators to adjust shuttle (forward-to-reverse), steering and blade sensitivity to Smooth, Moderate or Aggressive to match conditions on the site. The 2050M meets emissions regulations through a selective catalytic reduction (SCR)-only system that, as an aftertreatment solution, ensures that all productive power is put towards the work. A robust undercarriage matched with numerous track and blade configurations - as well as specialty guarding, kits and accessories - make the 2050M extremely versatile no matter how heavy the work. 214 horsepower and more than 81,000 pounds of drawbar pull make the 2050M a beast for all applications, whether land clearing, site development or landfill operations.
