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 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.

With ignition switch in RUN position and NGS/WDS connected to vehicle, enter function test menu. 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. 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.
