VIEW DATA
The View Data function allows you to view the vehicle’s Parameter Identification
(PID) data in real time. As the computer monitors the vehicle, the information is
simultaneously transmitted to the scan tool. Apart from Read 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 status of
switches, solenoids, and relays.
Select View Data from the OBDII
Function List and press
(17(5 .
The scan tool asks the vehicle to provide
the global PIDs it supports and generates
a list.
The Select Data To View menu displays.
Select Display Data to view the PIDs or
Change Display Set to change the
number of lines displayed on the screen.
Selecting fewer lines provides faster
update rates. The default is four lines.
Press
(17(5 to establish a communication link.
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.
Use the
83'2:1 arrow keys to move
through the list. Use the
/()75,*+7 arrow keys to page up/down.
