HUB-REACTION 1378628 - 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, UENR2346, "Calibration Error Codes".Required Tools

Transmission/Chassis ECM Calibrations
The following calibrations can be performed to the Transmission/Chassis ECM:
Transmission Fill Calibration
Payload System Calibrations
Machine Cooling Fan Calibrations
Payload Correction Factor CalibrationTo access the calibration procedures for the 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 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 to complete the calibration procedure.Chassis ECM Calibrations
The following calibration can be performed to the Chassis ECM:
Inertial Measurement Sensor Sensor 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.
