In this presentation we address three subjects: the J2534 or JBOX interface, the automotive scan tool and EEPROM work or EEPROM programming. We describe where each option is used by the automotive technician to solve a particular problem. We also cover exactly what happens with the electronics inside a vehicle module. This enhances your understanding of why care should be taken with J2534 programming. The difference between J2534 programming and scan tool work is also addressed. EEPROM work is also covered with an actual example. We use Automotive Kit#1 to clone the eeprom data from one GM Cadillac ECU to another.
