Key Programming - Security Access Procedure

NOTE:
- The Security Access Procedure is utilized to obtain passive anti-theft system (PATS) security access. PATS security access must be granted to erase ignition keys, enable/disable the spare key programming switch (PID SPARE_KY) or perform a parameter reset for PATS, and may be required to program ignition keys. The Security Access Procedure invokes an inherent 10-minute time delay prior to granting security access during which NGS must remain connected to the vehicle. Once security access has been granted, a security access command menu is displayed which offers various command options. Refer to MODULE CONFIGURATION PRINCIPLES OF OPERATION.
- Select only the command required by the appropriate pinpoint test.

1. From NGS Tester: Using service card, select PATS. Enter SECURITY ACCESS PROCEDURE. This procedure will take 10 minutes to perform, during which the ignition switch must be in RUN and the NGS Tester must be connected to the vehicle.
2. After the 10-minute security access procedure has been completed, a new menu will be displayed with command options. Select only those functions required before exiting cut of this menu. Once exited out of this menu, the security access procedure must be performed again to perform additional commands.
