Key Programming (Security Access Procedure)
NOTE:
Security access must be granted to erase ignition keys, enable/disable spare key programming switch, or perform parameter resets for PATS or PCM. This procedure has a 10 minute time delay prior to granting security access during which New Generation Star (NGS) Tester (49-T088-0A0) must remain connected to vehicle. After security access has been granted, security access command menu is displayed which offers various command options. Multiple security access commands can be executed (if necessary) prior to exiting security access command menu. Execution of all necessary security access commands prior to exiting command menu avoids performance of an additional security access procedure and associated 10 minute time delay. Security access for PATS and security access for PCM must be obtained separately as needed (each will require a 10 minute time delay).
With ignition switch in RUN position and NGS tester connected to DLC, select DIAGNOSTIC DATA LINK. Select PATS - PASSIVE ANTI-THEFT MODULE. Select FUNCTION TESTS. Select SECURITY ACCESS (1). This procedure will take 10 minutes to perform. After security access procedure has been completed, a new menu will be displayed with command options. Select as many functions as required before exiting this menu. Once this menu is exited, security access procedure must be performed again to perform additional commands.
