Some of the components that are connected to the Transmission or Implement ECM 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 Testing and Adjusting, "Calibration Error Codes".

Transmission ECM and Implement ECM Calibration screen | |
The following calibrations can be performed to the Transmission ECM:
- Neutralization Setpoint and Pedal Calibration
- Transmission Fill Calibration
To access the calibration procedures for the Transmission 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.
Transmission Warming Procedure
- Apply the parking brake. Ensure all clutches have been activated at least twice by shifting through all forward and all reverse gears two times with the engine at low idle. This ensures transmission oil has been worked through the system.
- With the parking brake applied and the engine running at high idle, shift the transmission into 4F and hold for 20 seconds.
- Keeping the parking brake applied and the engine running at high idle, shift the transmission to neutral and hold for 3 seconds.
- Repeat Step 2 and Step 3 until the transmission oil is at the desired temperature.
Note: Unless otherwise specified, do not allow the torque converter outlet temperature to rise above
The following calibrations can be performed to the Implement ECM:
- Lift Lever Calibration
- Tilt Lever Calibration
- Lift Linkage Sensor Calibration
- Tilt Linkage Sensor Calibration
- Arm Steering System/Solenoid Calibration
- Implement Raise Valve #1 Calibration
- Implement Lower Valve #1 Calibration
- Implement Rackback Valve #1 Calibration
- Implement Dump Valve #1 Calibration
- Implement Rackback & Dump Valve (Max Current) Calibration
- Autodig Rackback Valve Calibration
- Implement Raise Valve (Max Current) Calibration
- Empty Bucket Weight Calibration
- Full Bucket Weight Calibration
- Steering Physical Stop Calibration
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.
