Actron 9640 Manuel D’Utilisation

To diagnose a vehicle, connect the DLC and 

power adapter (if applicable) to the scan tool. 

Refer to “Diagnostic Link Connectors (DLC)” 

on page 2-5 of Getting Started.
If you just want to power up the tool to do its 

self-tests, code lookup, review or printing data 

from the last vehicle tested, then you do not need 

to attach the cable to the Data Link Connector. The internal battery provides 

power for this. 
When the scan tool powers up, a series 

of messages display on the screen 

beginning with a “Welcome” screen and 

ending with a “Key Button Help” screen. 

otherwise, press 

ENTER  to continue.

When the tool powers up, the “Key Button Help” screen is followed by a Main 

Menu screen. 
Pick Vehicle Diagnosis to begin 

Vehicle Selection. If there is a previous 

vehicle present, the tool displays that 

vehicle. You can choose the last vehicle 

selected or setup for a new vehicle. The 

tool retains all data retrieved from the 

last vehicle selected until any of the 

following occurs:

❒

A new vehicle is selected 

❒

Internal AAA batteries are depleted or disconnected

❒

Tool is flash programmed to update software

❒

The last vehicle selected is kept but you choose Erase Data

You can either keep the previously 

selected vehicle or change it. If 

changing the vehicle, press the 

RIGHT 

arrow key and press 

ENTER. 

Otherwise, press 

ENTER to keep the 

current one.

The next screen asks if you want to 

erase the stored data. The default is NO. 
After pressing 

ENTER, the function list 

displays.
