Multiple PIDs may be sent if the vehicle is equipped with more than one
computer module — Powertrain Control Module (PCM), Transmission Control
Module (TCM), etc. The scan tool identifies them by their identification names
(ID) assigned by the manufacturer (i.e. $40 or $1F).
If the Scan Tool receives multiple
responses for a PID, such as MIL
STATUS, it displays the PID and with
the computer module ID blinking in
parentheses.
If one or more control modules stops
responding, the tool will display a
message that it is not responding. If you
choose to continue, dashes will replace
the module ID.
