Schematic for the "Tilt Cylinder Regeneration" Solenoid
This diagnostic code is recorded when the Implement ECM determines that the solenoid valve is out of calibration.The possible causes for this diagnostic code are listed below:
New software has been flashed.
The calibration of the valve has failed.System Response:The deadband in the control lever may be excessive. The operation of the control lever may be jerky.Note: Ensure that the diagnostic code is active.Test Step 1. CHECK CALIBRATION.
Calibrate the main control valve. See Testing and Adjusting, "Main Control Valve (Operator Monitor) - Calibrate" or Testing and Adjusting, "Main Control Valve (Operator Monitor) - Calibrate".
Recheck the diagnostic code.
Ensure that the diagnostic code is active.
Observe the ON/OFF status of the diagnostic code indicator as the auxiliary function is fully actuated. Expected Result:The diagnostic code indicator is inactive.Results:
YES - The diagnostic code indicator is inactive.Repair: The diagnostic code is not active now. Calibration corrected the diagnostic code. Clear the diagnostic code. STOP
NO - The diagnostic code indicator is active.Repair: Failure of the Implement ECM is unlikely. Perform calibration for the Main Control Valve again. Also, ensure that the diagnostic code indicator is active for this diagnostic code. If the cause is not found, replace the solenoid and perform the calibration again. If the diagnostic code is still active, replace the ECM. Refer toTesting and Adjusting, "Electronic Control Module (ECM) - Replace".STOP
