COVER 6N2837 - Caterpillar

Introduction
Some of the components that are connected to the electronic control modules can be calibrated by using the Caterpillar Electronic Technician (Cat ET).Calibrations are performed when directed by troubleshooting procedures or replacing a component within the calibrated system.The calibration of a component allows the ECM to determine the correct output level. The calibration also allows the ECM to determine the correct input signal of displacement.For more information on error codes that may occur during calibration refer to Testing and Adjusting , UENR3825, "Calibration Error Codes".Required Tools

Implement ECM Calibrations
The following calibrations can be performed to the Implement ECM:
Lever Calibration
Implement Pump Swash Plate Angle Sensor Calibration
Linkage Sensor Calibration
Arm Steering Systems/Solenoid Calibration
Valve Calibrations
Steering Physical Stop CalibrationTo access the calibration procedures for the Implement ECM, establish the connections of the Cat ET to the machine. Navigate to the calibration screen by clicking "Service" on the tool bar and then clicking "Calibrations". Select the desired calibration procedure that is required. Click on the "Start" button at the bottom of the screen.Once the specific calibration is selected, the Cat ET will guide you through the calibration procedure.The Cat ET will list initial machine conditions that must be satisfied before the ECM will allow the calibration procedure to continue. Follow the specific instructions on the display in order to complete the calibration procedure.Transmission ECM Calibrations
The following calibration can be performed to the Transmission/Chassis ECM:
Transmission Hydrostatic Torque Calibration
Decel/Brake Pedal Calibration
Transmission Clutches Fill CalibrationTo access the calibration procedures for the Trans/Chassis ECM, establish the connections of the Cat ET to the machine. Navigate to the calibration screen by clicking "Service" on the tool bar and then clicking "Calibrations". Select the desired calibration procedure that is required. Click on the "Start" button at the bottom of the screen.Once the specific calibration is selected, the Cat ET will guide you through the calibration procedure.The Cat ET will list initial machine conditions that must be satisfied before the ECM will allow the calibration procedure to continue.
