7. DIAGNOSTIC TESTER REQUIREMENTS
7.1.1 Diagnostic Tester Introduction
• The Smartra needs the Diagnostic interface to change state of Smartra to [neutral] state from the
[learnt] state in the field.
• The Smartra needs to use the Diagnostic PIN Number (DPN) to generate the Secret Encryption Key
(SEK).
• For Security reasons the Diagnostic PIN Number (DPN) is required to access the diagnostic function,
PIN number protection is required for security reasons. Once the Diagnostic PIN Number (DPN) is
taught to the [virgin] or [neutral] Smartra the Smartra enters [learnt] state. The OEM secure
Diagnostic PIN Number (DPN) is taught to the Smartra:
taught to the [virgin] or [neutral] Smartra the Smartra enters [learnt] state. The OEM secure
Diagnostic PIN Number (DPN) is taught to the Smartra:
o
at the OEMs end of line tester after the car is assembled.
o
in the field when a Smartra is replaced with a [virgin] Smartra.
• The Diagnostic PIN Number (DPN) will be:
o
a 9 byte number that will be Thatcham compliant selected by OEM.
o
the OEM will be responsible to maintain a database for Diagnostic PIN numbers (DPN’s)
matching with VIN numbers.
o
the diagnostic PIN number will be stored on both the EMS and the Smartra.

7.1.3 Programming Diagnostic PIN Number DPN (on the Smartra)
The Smartra will learn the 9 byte Diagnostic PIN Number (DPN) at the OEMs end of line tester or in the
field when a module is replaced.
The Diagnostic PIN Number (DPN) will inhibit placing the Smartra3 into [Neutral] state from [Learnt] state
for security reasons.
A new Smartra ECU will be delivered with no Diagnostic PIN Number (DPN) programmed into EEPROM.
In this “production mode” status, all diagnostic functions will be available without having to enter or
program a pin code previously.
Once the Diagnostic PIN Number (DPN) is programmed to the ECU at the car assembly plants end of
line tester, all diagnostics functions are possible until the end diagnostic command is transmitted from
the tester to the control unit or the car assembly plants end of line tester is removed from the vehicle.
This is to say, once the Diagnostic PIN Number (DPN) has been programmed, it does not have to be
entered again to access secured diagnostic functions until the current diagnostic session is completed.
