KIT-SEAL 3866630 - Caterpillar

Which Generate This Code:This diagnostic code is recorded when the implement electronic control module (ECM) determines that the auxiliary lever position sensor is out of calibration. The auxiliary lever position sensor is a PWM sensor.The possible causes for this diagnostic code are listed:
The auxiliary lever has operated outside the calibrated range for more than three seconds.System Response:The machine response is listed:
Implement features will not operate.
The machine must be restarted in order to allow the auxiliary function to operate.Note: Ensure that the diagnostic code is active.Test Step 1. CHECK THE ADJUSTMENT FOR THE SENSOR .
Adjust the auxiliary position sensor so the duty cycle is within 43 to 57%. The lever must be centered when this adjustment is performed.
Recheck the diagnostic code.
Ensure that the diagnostic code is active.
Observe the ON/OFF status of the diagnostic code as the auxiliary function is fully actuated.Expected Result:The diagnostic code is inactive.Results:
YES - The diagnostic code is inactive.Repair: The diagnostic code is not active now. Adjustment corrected the diagnostic code. Clear the diagnostic code. Stop.
NO - The diagnostic code is active.Repair: It is unlikely that the ECM has failed. Perform calibration for the Lift Lever Position Sensor. Also, ensure that the diagnostic code is active. If the cause is not found, replace the sensor and perform the calibration again. If this does not eliminate the diagnostic code, replace the ECM. See Testing and Adjusting, "Electronic Control Module (ECM) - Replace". Stop.
