should determine if the problem with the machine is still present. You should use the monitor and the "Real Time Error Codes" function of the "Data Mode" in order to determine if any system faults are detected in the electronic system. If there are any real time error codes, follow the procedure for the error code. See the topic Testing and Adjusting, "Troubleshooting Diagnostic Codes". Otherwise, the problem is not likely to be in the electronic control system. Perform the operational test for the machine that is being serviced. Follow the procedures that are described in the "Testing And Adjusting" section of the service manual for the Hydraulic System. Compare the results of the operational tests with the specifications in order to determine the extent of the problem. You should determine whether the hydraulic force is adequate or the implement speed is a problem, when you use an operational test. These problems can involve the entire machine or the problem can affect only a specific operation. The overall performance of the machine will be decreased, if any faults occur in the circuits of the main pump or the pilot pumps and the control valves. This type of problem in the hydraulic system is not detected by self-diagnostics of the control system. To detect such a problem, it is necessary to check the flow characteristics of the pumps, the main relief pressure, pilot pressure, etc.
