VIEWING VEHICLE INFORMATION
The
Vehicle Information
function offers
three options for retrieving reference
information for the vehicle under test;
Vehicle ID
,
Available Modules
and
IPT
(In-Use Performance Tracking).
Retrieving Vehicle ID Information
The Vehicle ID function is applicable to model year 2000 and
newer OBD2-compliant vehicles.
The Scan Tool can retrieve a list of information (provided by the vehicle
manufacturer), unique to the vehicle under test, from the vehicle's on-
board computer. This information may include:
The vehicle's VIN number
The control module identification number
The vehicle's calibration ID(s). These IDs uniquely identify the
software version(s) for the vehicle's control module(s).
The Vehicle's Calibration Verification Number(s) (CVNs) required by
ODB2 regulations. CVNs are used to determine if emission-related
calibrations for the vehicle under test have been changed. One or
more CVNs may be returned by the vehicle's computer.
