Schematic of the "Boom Angle" potentiometerThis diagnostic code is recorded when the ECM records a signal from the potentiometer for the boom angle that is out of calibration. The output of the potentiometer is voltage. The signal wire for the potentiometer connects to contact J1-05 (wire E441-GN) of the ECM.For machines equipped with the E-Fence feature, reference Troubleshooting, "E-Ceiling and Cab Avoidance - Troubleshoot"The possible causes of this diagnostic code are listed below:
New software has been installed, and the sensor has not been calibrated.
The position sensor is above or the position sensor is below the calibration range for more than 3 seconds.System Response:The machine response is listed:
The implement features will not work.
The calibration procedure for the boom angle will not work properly.
The calibration procedure for the boom angle may not function properly.Note: Ensure that the diagnostic code is active and that the diagnostic code indicator is active.Test Step 1. CHECK CALIBRATION
Calibrate the "Boom Angle" position sensor. Refer to the Testing and Adjusting, "Calibration" procedure. Verify that the new potentiometer corrects the problem.
Ensure that the diagnostic code is active.
Observe the status of the diagnostic code as the boom angle is fully raised and fully lowered.Expected Result:The diagnostic code is inactive.Results:
YES - The diagnostic code is inactive.Repair: The diagnostic code is inactive now. Calibration corrected the diagnostic code. Clear the diagnostic code.STOP
NO - The diagnostic code is active.Repair: The diagnostic code remains active. Is unlikely that the ECM has failed. Perform calibration for the "Boom Angle" sensor again. Also, ensure that the diagnostic code indicator is active for this diagnostic code. If the cause is not found, replace the potentiometer and perform the calibration again. If that does not eliminate the diagnostic code, replace the ECM. If a fault becomes active, is possible that the mounting for the sensor may be loose. The mounting should be checked. See Testing and Adjusting, "Module - Replace".STOP
