If the vehicle under test was manufactured after 1998 the ‘Auto Search 1998>’ option
should be used. This option prompts the OmiCheck to automatically identity the
Engine Control Module.
If the vehicle under test was manufactured before 1999, or the operator knows the
Engine Code of the vehicle or the name of the Engine Control Module, the ‘Engine
Size/Code’ or the ‘Control Unit’ option should be used. These options should also be
used in the rare cases where the Auto Search option cannot identify the Engine
Control Module on post -1998 vehicles.
