sensors.
Check the mounting bolts for the articulation sensors. Ensure that the sensors are securely mounted.
Visually inspect the mechanical linkage for the articulation sensors. Verify that all mechanical components are tight and that all components are in good condition. Verify that the adjustment of the linkage is correct. Expected Result:All mechanical linkage and adjustment components for the articulation sensor(s) are in good condition and no mechanical connections are loose.Results:
OK - All mechanical linkage and adjustment for the articulation sensor is correct. Proceed to Test Step 2.
NOT OK - All mechanical linkage and adjustment for the articulation sensors is not correct. Repair: Perform the maintenance that is required in order to correct the problem with the mechanical connections for the articulation sensor(s). After the problem has been corrected, verify that this diagnostic code is still active before proceeding with this procedure.STOPTest Step 2. CHECK FOR POWER AT THE SENSOR
Turn the key start switch and the disconnect switch to the OFF position.
Do not disconnect the harness connector from the sensor.
At the back of the harness connector for the sensor, insert 7X-1710 Multimeter Probes along the contact for the power circuit A (wire R800-OR(Orange)) and spoon along the contact for the return circuit B (wire P967-PU(Purple)).
Turn the key start switch and the disconnect switch to the ON position.
Measure the voltage from contact A to contact B. Expected Result:The voltage measurement is 8.0 0.5 VDC.Results:
OK - The voltage measurement is 8.0 0.5 VDC. The power supply circuit is correct. Proceed to Test Step 3.
NOT OK - The voltage measurement is not 8.0 0.5 VDC. The power supply circuit is not correct.Repair: There is a problem with the 8 VDC power supply circuit of the Implement ECM 2 for the sensor. Refer to the complete Electrical System Schematic of the machine. Check all of the connections that are in the power supply circuit and the return circuit. Ensure that all connections are clean, that all connections are secure and that all connections are in good condition. Repair the machine harness or replace the machine harness. STOPTest Step 3. CHECK THE SIGNAL OF THE SENSOR
Turn the key start switch and the disconnect switch to the OFF position.
At the back of the harness connector for the sensor, remove the multimeter probe from contact A (wire R800-OR(Orange)) and spoon the probe along the signal contact C (wire E929-GY(Grey)).
The spoon at return contact B (wire P967-PU(Purple)) remains in place.
Turn the disconnect switch and the key start switch to the ON position.
Monitor the signal of the sensor with a digital multimeter.
Without disconnecting the sensor or the hardware that is associated with the sensor from the machine, take the sensor through the full operating range. Expected Result:The signal from the sensor responds in the manner that is described at the beginning of this procedure.Results:
OK - The signal of the sensor responds correctly. The sensor is operating correctly. Proceed to Test Step 4.
NOT OK - The signal of the sensor does not respond correctly. The sensor is
