This function allows the device to send information to, and receive
information from, vehicle control modules. For example, in the
case of OBD II generic information Mode 1 (which relates to data
parameters), the scan tool user initiates a request for information
from the powertrain control module (PCM), and the PCM responds
by sending the information back to the scan tool for display. Most
enhanced scan tools also can actuate relays, injectors and coils,
perform system tests, etc. Users could check the individual part to
see what is working properly by actuation test.
