Cat ET 2001B-Service Pack 1 software upgrade is now available through Cat ET Web Sites or by contacting the Service Systems Support Center.

New Features in Cat ET 2001B-Service Pack 1 Software Upgrade

• Cat ET 2001B-Service Pack 1 software upgrade contains Oxygen Sensor Calibration for current gas engines that were previously supported by Digital Diagnostic Tool (DDT). The new software compensates for tolerances in the oxygen sensor element and the buffer in order to ensure that the engine meets emissions standards.

• Cat ET 2001B-Service Pack 1 software upgrade contains Magneto Calibration for current gas engines that were previously supported by DDT software. The new software allows adjustments to ensure proper engine timing.

• Cat ET 2001B-Service Pack 1 software upgrade contains Engine Load Feedback Calibration for 3500 marine engines. The new software adjusts the Engine Load Feedback Calibration electrical current output for the load points.

• The issue with the Cylinder Cutout Test for 3126 HEUI engines has been corrected. The automatic capability of the 3126 Cylinder Cutout Test was not functional for the Cat ET 2001B software release. The issue has been corrected and the test is now fully functional with the Cat ET 2001B-Service Pack 1 software upgrade.

• Histograms may be printed from Cat ET within Service Technician Workbench.
