Additional OBD2 Tests
VEHICLE ID
Some vehicle manufacturers do
not allow CanOBD2&1 Scan Tools
or other external devices to con-
trol vehicle systems. If the EVAP
Leak Test is not supported by the
vehicle under test, an advisory
message shows on the
CanOBD2&1 Scan Tool's display.
Press the ENTER/LD
button
to return to the System Test menu.
4. When the EVAP leak test has been initi-
ated by the vehicle's on-board comput-
er, a confirmation message shows on
the CanOBD2&1 Scan Tool's display.
Press the ENTER/LD
button to
return to the “Select Test” screen.
VEHICLE ID
The Vehicle ID function offers two options for retrieving reference
information for the vehicle under test; Vehicle ID and Available
Modules.
Retrieving Vehicle ID Information
The Vehicle ID function is applicable to model year 2000 and
newer OBD2-compliant vehicles.
The CanOBD2&1 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 soft-
ware 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.
1. From the "Mode Selection Menu", use
the UP
and DOWN
buttons, as
necessary, to highlight Vehicle ID, then
press the ENTER/LD
button.

The "Vehicle Information Menu" dis-
plays.
