994H Wheel Loader Electrohydraulic System Caterpillar


Calibrations (Cat ET)

Usage:

994H DWC
The calibration of a component in the Implement ECM allows the ECM to determine the correct output level. The calibration also allows the ECM to determine the correct input signal of displacement.

Some of the components that are connected to the Implement ECM can be calibrated by using the Caterpillar Electronic Technician (Cat ET).

Implement ECM Calibration screen

To 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". 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.

Note: The "CALIBRATION REQUIRED" diagnostic will be active and the ECM will revert to the previous successful calibrated values if a calibration is aborted at any time. In order to clear the diagnostic, cycle the key.

The following list details the calibrations that can be performed for the components on the Transmission ECM.

  • Center Pump Calibration

  • Left Rear Pump Calibration

  • Left Front Pump Calibration

  • Right Pump Calibration

  • Tilt Lever Calibration

  • Lift Linkage Sensor Calibration

  • Tilt Linkage Sensor Calibration

  • Implement Raise Valve #1 Calibration

  • Implement Lower Valve #1 Calibration

  • Implement Rackback Valve #1 Calibration

  • Implement Dump Valve #1 Calibration
