TANK GP-COOLANT 2501172 - Caterpillar

Conditions that Require Recalibrating
The implement electronic control system must be calibrated in order to obtain optimum performance. The procedure consists of the calibration procedure for the lift lever position sensors and the calibration procedure for the valve. The calibration procedure must be followed in order. The implement electronic control system must be calibrated when the following conditions exist:
A new machine is received without a work tool and a work tool is installed.
A work tool is exchanged and the operator notices a different “feel”. This indicates an unacceptable change in hydraulic modulation. If the machine requires frequent changing of the implement, calibration should be performed with the implement that is used most frequently. This calibration should be used with all other implements.
Electronic components and hydraulic components are replaced or components are adjusted. This includes the following examples:
Replacing the ECM
Replacing or changing positions of the electro-hydraulic system's valves
Replacing or changing positions of the solenoid valves
Replacing a linkage position sensor
Replacing a lever position sensor
Changing the position of a lever position sensor or changing the position of a linkage position sensor
Replacing all of the main implement valve
Replacing part of the main implement valve
Attachments have been added. The attachments increase the weight of the system: additional side plates, cutting edges and liners. Note: The implement electronic control system does not need to be calibrated when the same work tool is removed and installed.Calibration Problems
The following troubleshooting guide can be used to identify probable causes of calibration problem and the necessary corrective actions needed. Refer to the appropriate calibration procedure sections. Also, refer to Systems Operation, "Implement Electronic Control System".Problem 1: The kickout position cannot be set as required in Testing and Adjusting, "Main Control Valve (Electronic Technician) - Calibrate" or Testing and Adjusting, "Main Control Valve (Operator Monitor) - Calibrate".Probable Cause 1 - Calibration of the lift linkage position sensor is required.Corrective Action - Refer to Testing and Adjusting, "Position Sensor for the Lift and tilt Linkage (Electronic Technician) - Calibrate" or Testing and Adjusting, "Position Sensor for the Lift Linkage (Operator Monitor) - Calibrate".Probable Cause 2 - Input from the lift linkage position sensor is not being read by the ECM.Corrective Action - Check the options code for the implement ECM.Problem 2: No duty cycle value displayed in Testing and Adjusting, "Main Control Valve (Electronic Technician) - Calibrate" or Testing and Adjusting, "Main Control Valve (Operator Monitor) - Calibrate".Probable Cause 1 - Input from the lift linkage position sensor is not being read by the ECM.Corrective Action - Check the options code for the implement ECM.Probable Cause 2 - The Cat Data Link has an open circuit.Corrective Action - Reconnect the data link.Problem 3: The "READY" message does not display in Testing and Adjusting, "Main Control Valve (Electronic Technician) - Calibrate" or Testing and Adjusting, "Main Control Valve (Operator Monitor) - Calibrate".Probable Cause 1 - The engine speed is too low.Corrective Action - Increase engine speed to high idle.Probable Cause 2 - The lift arms are drifting excessively.Corrective Action -
