The professional scan tool MaxiDiag
PRO
MD801 is able to work with
global OBD II/EOBD compliant vehicles but also able to diagnose
non-OBD II compliant vehicles. It is specially designed to read and
clear trouble codes, and to retrieve ECU information of engine,
automatic transmission, ABS and airbag systems for Asian, European
and American vehicles.
For most pre-OBD II vehicles, they do not have standard 16-pin OBD
II DLC (Data Link Connector). You need to have proper diagnostic
connectors to diagnose them.
