Increase your ability to diagnose high-tech, OBD-II vehicles. Delphi's unique diagnostic repair process and OBD-II diagnostic database contain actual measured, amperage-based readings that appear on a circuit-by-circuit basis for most OBD-II compliant vehicles. For the first time, technicians have the ability to determine whether a system fault is caused by a component, computer or wiring. The process leads technicians to an accurate diagnosis in a minimum amount of time. The OBD-II Diagnostic Suite also contains measured readings and specifications for most other electronic vehicle systems.
