System requirements

The system requirements applicable to SDP3
can be found on the Technical Information
Library website which can be accessed via
Reflex.

Ancillary equipment

Use of the program requires a computer, a USB
key and a VCI. These components must comply with the applicable system requirements for
the program to work correctly. For more information, see System requirements.

USB key
A USB key supplied by Scania is required. In
accordance with the applicable agreements, the
USB key is the property of Scania. This means
that you should report a stolen or lost USB key
to Scania, where it is entered in a list of
blocked IDs. To do this, contact your distributor who will in turn contact Scania.
Distributors can find more information on USB
keys in the VCI and USB procedures for external administration. This can be accessed via
Reflex under the Reflex/Service Operations/
Application/VCI & USB keys tab.

The main menu in Show licence information in
SDP3 contains information about the software
licence in use and also describes the current
access level.
The USB key controls access, i.e. which parts
of the program you have access rights to.
A different type of USB key is required
depending on whether you will be working on
a vehicle or an industrial and marine engine.
If access is shown as BLOCKED, this implies
that Scania has entered the USB key in a list of
blocked IDs. If access is shown as
UNKNOWN, this indicates that the USB key is
of a different type to the one approved by Scania.
