Schematic for the Lift Lever Sensor
This diagnostic code is recorded when the Implement ECM determines that the Lift Lever Sensor is out of calibration. The Lift Lever Sensor is a PWM sensor.The possible causes for this diagnostic code are listed:
The lift lever has operated outside the calibrated range for more than three seconds.System Response:The machine response is listed:
Implement features will not operate.
Lever will operate with increased deadband.
Table 1
Duty Cycle Signal as a Function of Control Lever Position
Lever Position Approximate Duty Cycle
Tilt Lever Full Forward Travel 10% to 15%
Tilt Lever Full Rearward Travel 85% to 90%
Lift Lever Full Forward Travel 10% to 15%
Lift Lever Full Rearward Travel 85% to 90% Note: Use Cat ET in order to verify the duty cycle of each lever position.Note: Ensure that the diagnostic code is active.Test Step 1. RECALIBRATE THE LEVER POSITION SENSOR.Recalibrate the lever position sensor. Refer to Testing and Adjusting, "Calibrations (Cat ET)".Expected Result:A successful calibration causes this diagnostic code to become inactive. Results:
YES - The calibration causes this diagnostic code to become inactive. Resume normal machine operation.STOP
NO - The calibration has not caused the diagnostic code to become inactive.Repair: Use Cat ET in order to verify the duty cycle of each lever position. Refer to table 1. If the duty cycle values are not correct, replace the lever/joystick.STOP
