Introduction

Some of the components that are connected to the Machine 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.

Machine ECM Calibrations

The following calibrations can be performed to the Machine ECM:

Engine Cooling Fan Calibration

Engine Cooling Fan Minimum Speed
Engine Cooling Fan Maximum Speed

Decel/Brake Pedal Calibration

Decel/Brake Pedal Calibration

Drive Motor Solenoid Calibration

Drive Motor Solenoid Calibration

Note: To calibrate the drive motor solenoid the machine must be safely lifted and supported, such that the wheels are off the ground and can safely spin.
