Actron 9640 Manuel D’Utilisation

The View Data function allows the user to view the vehicle Parameter 

Identification Data (PIDs) in real time. As the PCM monitors PIDs, they are 

simultaneously transmitted to the scan tool. The PIDs are continuously updated 

at the PCM’s rate.
In addition to reading codes, View Data is the most useful diagnostic function 

for isolating the cause of a vehicle operation problem. Viewing data is also used 

for observing sensor data and the ON/OFF state of switches, solenoids, and 

relays.
View Data can be performed with the ignition key On-Engine Off or Running.

a time.

to establish a communication link.

Use the 

UP/DOWN arrow keys to scroll 

through the PIDs.

beginning. 

Change the selection of Custom Data List parameters at any time by pressing 

the 

BACK key. This returns to the Custom Data List selection screen.
