GEAR-FLYWHEEL 8M6755 - Caterpillar

The Caterpillar Electronic Service Tools are designed to perform the following functions:
Obtain data from the engine.
Display the diagnostic codes or display the event codes on the Caterpillar Electronic Technician (ET).
Perform sensor calibrations.
Read the programmable parameters.
Change the programmable parameters.The use of a communication adapter must be used in order for the Cat ET to communicate with the Electronic Control Module (ECM).There are several service tools that are required in order to allow a service technician to perform the procedures. These tools are listed in the following tables.
