VIEW DATA
The View Data function allows “real time” viewing of vehicle’s Parameter
Identification (PID) data. As computer monitors vehicle, information is
simultaneously transmitted to scan tool. Apart from Read Codes, View Data is
the most useful diagnostic function for isolating cause of a vehicle operation
problem. Viewing data is also used for observing sensor data and status of
switches, solenoids, and relays.
Select View Data from OBDII Function
List and press
ENTER
.
Scan tool asks vehicle to provide global
PIDs it supports.
After generating PID list, scan tool
displays menu with display options.
Use
UP/DOWN
to select option and
press
ENTER
. Refer to “Viewing Data”
on page3-11 to setup data list.
After making selection, press
ENTER
to establish a communication link.
Multiple PIDs may be sent if vehicle is equipped with more than one computer
module — Powertrain Control Module (PCM), Transmission Control Module
(TCM), etc. Scan tool identifies them by their identification names (ID) assigned
by manufacturer (i.e. $40 or $1F).
If Scan Tool receives multiple
responses for a PID, such as MIL
STATUS, Scan Tool displays PID and
with computer module ID blinking in
parentheses.
