Security Access Procedure

2002 Pontiac Grand Prix SE, 3.1 JSECTION Security Access Procedure

NOTE: Security access must be granted to erase ignition keys, enable/disable spare key programming switch, or perform parameter resets for instrument cluster and PCM. This procedure has a 10-minute time delay prior to granting security access during which the New Generation Star (NGS) or Worldwide Diagnostic System (WDS) tester 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 the performance of an additional security access procedure and the associated 10-minute time delay.

Insert Ford Service Function (FSF) card into NGS/WDS tester. Turn ignition switch from OFF to RUN position. With NGS/WDS tester connected to vehicle, select HEC or VIC, then select SECURITY ACCESS PROCEDURE. This procedure will take 10 minutes to perform. After the security access procedure has been completed, a new menu will be displayed with command options. DO NOT perform ignition key code erase. Before exiting SECURITY ACCESS PROCEDURE menu, PARAMETER RESET command must be selected. Once SECURITY ACCESS PROCEDURE menu is exited, security access procedure must be performed again to perform additional commands.
