Anti-Theft Security Access

Anti-Theft Security Access





NOTE: The anti-theft security access procedure is used to obtain Passive Anti-Theft System (PATS) security access. PATS security access must be granted to reset parameters in the Instrument Cluster (IC) and PCM, erase ignition key codes, program ignition key codes, program spare keys, enable/disable the unlimited key mode, set the unlimited transponder key ID and enable/disable the spare key programming switch (IC PID SPAREKEY). This procedure invokes a 10-minute time delay prior to granting security access, during which the scan tool must remain connected to the vehicle. Once security access is granted, a security access command menu is displayed, which offers various command options.

NOTE: Once security access has been granted, multiple security access commands should be executed (if necessary) prior to exiting the command menu. This avoids an additional security access procedure and the associated 10-minute time delay.

1. From the scan tool, enter TOOLBOX. Select BODY - SECURITY - PATS Functions and follow the Integrated Diagnostic System (IDS) on-screen instructions to ENTER SECURITY ACCESS. This procedure takes approximately 10 minutes to carry out, during which time the ignition key must be in the ON position and the scan tool must be connected to the vehicle.

2. After the 10-minute security access procedure is completed, a new menu is displayed with command options. Select only those functions required before exiting out of this menu. Do not select more functions than the procedure calls for or a PATS no-start may occur. Once exited out of this menu, the security access procedure must be repeated again to carry out additional commands.
