Introduction
Some of the components that are connected to the electronic control modules can be calibrated by using the AVSpare 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 Specifications, Systems Operation/Testing, and Adjusting, UENR4109, "Calibration Error Codes".

Machine ECM Calibrations
The following calibrations can be performed to the Machine ECM:
- Brake Touch-Up Pressure Calibrations
- FNR Shifter Sensor Calibration
- Service Brake Pedal Calibration
- Steering Control Position Sensor Calibration
- Transmission Fill Calibration
To access the calibration procedures for the Machine 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". Click on the calibration that is needed.
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.
