  2. The program allows users to read out and clear fault codes, shows you live data and perform output test.
  3. The program supports many control units, like Engine, Automatic Transmission, ABS, Airbag, Engine Cooling module, Instrument Cluster, Electronic Climate Control, Body Control Unit, etc.
  4. Since Opel cars adopt many PINs in the OBD connector, the diagnostic interface works as a multiplexer,and users need select the appropriate pin for communication. PIN3, PIN7, PIN8, PIN12 = Serial Link (ISO9141, KW81, KW82, KWP2000)
  5. Fault codes will be shown with all information available:
