Multiple PIDs may be sent if vehicle is equipped with more than one
computer module (for example a powertrain control module [PCM]
andatransmissioncontrolmodule[TCM].TheToolidentiesthem

or$1A).SeePIDDenitionsformoreinformation.
If one or more control modules stop responding, the Tool displays a

 If NO is selected, the Tool will attempt to re-establish
communication with that module.
