Anti-Theft Security Access - Without Intelligent Access (IA)

Anti-Theft Security Access - Without Intelligent Access (IA)





NOTE: This procedure is used to obtain Passive Anti-Theft System (PATS) security access. PATS (Passive Anti-Theft System) security access must be granted to erase ignition keycodes, program ignition keycodes, program spare keys, enable/disable the unlimited key mode, set the unlimited transponder key ID, reset Instrument Panel Cluster (IPC) or PCM parameters and enable/disable the spare key programming switch (IPC (Instrument Panel Cluster) PID SPAREKEY). The anti-theft security access 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.

NOTE: If anti-theft security access has been entered to reset parameters, make sure to cycle the ignition several times, holding the key in each position for a minimum of 3 seconds. The vehicle may not start until the key has been cycled a minimum of 3 times. This allows the modules to send and receive the IDs after the parameter resets have occurred.

NOTE: When using the Integrated Diagnostic System (IDS), the IPC (Instrument Panel Cluster) and the PCM parameters are reset at the same time.

1. From the scan tool, enter TOOLBOX. Select BODY- SECURITY- PATS Functions and follow the IDS (Integrated Diagnostic System) 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 (Passive Anti-Theft System) no-start may occur. Once exited out of this menu, the security access procedure must be repeated again to carry out additional commands.
