Actron 9640 Manuel D’Utilisation

The EEC-IV/MCU DLC is a  large six-sided connector with a pigtail connector. 

The pigtail connector is not used on MCU vehicles – leave the  pigtail 

unattached. The EEC-IV/MCU cable adapter is included with the scan tool.

MECS vehicles (1988 –1995) use either a 6-pin (with pigtail) or a 17-pin DLC. 

Use the MECS 6-pin adapter cable kit (P/N 9603) for both configurations. The 

MECS adapter cable kit includes jumper wires to connect to the MECS 17-pin 

DLC. The MECS adapter cable kit is not included with this tool. It is available 

through your dealer. Use the following diagrams to connect the adapter cable.
