Security Access - Procedure
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 unlimited key mode, and enable/disable the spare key programming switch (PID SPARE KEY). The security access
procedure invokes an inherent 10 minute time delay prior to granting security access during which the diagnostic tool must remain connected to the
vehicle. Once security access has been granted, a security access command menu is displayed which offers various command options. See MODULE
CONFIGURATION PRINCIPLES OF OPERATION.
NOTE: Once security access has been granted, multiple security access commands should be executed (if necessary) prior to exiting the command
menu. This avoids the carrying out of an additional security access procedure and the associated 10 minute time delay.
1. From the diagnostic tool service function card, enter PCM. Select SECURITY ACCESS. This procedure will take 10 minutes to carry out, during
which the ignition switch must be in RUN and the diagnostic tool 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 out of this menu. Once exited out of this menu, the security access procedure must be repeated again to carry out
additional commands.
