STATOR-CONVERTER 6Y0803 - Caterpillar

Using Caterpillar Electronic Technician
The Caterpillar Electronic Technician service tool is used in order to access the calibration procedures. For more information, refer to the manual that was provided with the ET.Similar procedures for calibration may also be performed through the Monitoring System. See Systems Operation, RENR8068, "Calibration Mode".The calibration menu is used in order to compensate for the differences in the mechanical components and the electrical components. The calibration should be performed if the ECM has been replaced or the ECM was removed. The calibration should be performed if components have been replaced or removed. Perform all calibrations that are applicable.Note: Be sure the hydraulic oil temperature is at least 50 °C (122 °F) before performing calibrations.Accessing Calibrations
Connect the ET to the machine. See Illustration 1. After communication has been established, the ET will list the electronic control modules that are on the machine.

(4) Backup Control Switches Note: The ECM must detect specific set-up conditions before beginning the calibration procedure. If a set-up step is not met, the calibration procedure is aborted.
Select the Machine ECM.

Typical screen for accessing calibrations
Select "Service" from the main menu.
Select "Calibrations" from the "Service" drop-down menu. The following is a list of all possible calibrations from the "Calibrations" drop-down menu. The specific calibrations will differ across sales models.
"PRV - Main Pump Flow Limitation Pressure Calibration"
"PRV - Power Shift Pressure Calibration"
"Modulation Input Calibration"
"PRV - Variable Relief Pressure Calibration"
"PRV - Attachment Valves Pressure Calibration"
"Engine Speed Calibrations"
From the "Calibrations" drop-down menu, select the desired calibration procedure.
Follow the instructions that are provided on the screen. Note: Additional screens will be displayed to notify the operator of the status of the calibration procedure.Typical Calibration Screens
