    Section 2 – Getting Started The Professional Enhanced Scan Tool was developed by experts in the auto- motive service industry to help diagnose vehicles and assist in troubleshooting procedures. The tool monitors vehicle events and retrieves codes from the vehi- cle computer’s memory to pinpoint problem areas.
  • Page 16 Getting Started The original on-board diagnostics (OBD I) lacked consistency in communica- tion and interface while allowing different interpretations amongst vehicle man- ufacturers. Ford and Chrysler used different types of engine control computers and data link connectors, and GM varied the trouble codes and communication protocols from year-to-year.
