Calibrations (Operator Monitor)

Usage:

992K 880
The calibration of a component in the Transmission 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 Transmission ECM can be calibrated by using the Caterpillar® Electronic Technician (Cat® ET).

Calibrations should be performed on a surface that is smooth and level.

Press the "HOME" button (4) on the Advisor module to bring up the "HOME" menu.

The operator monitor 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 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 anytime. To clear the diagnostic, cycle the key.

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

  • Torque Converter Pedal Calibration

  • Impeller Clutch Solenoid

  • Lockup Clutch Engagement Calibration
