Anti-Theft Security Access

ANTI-THEFT SECURITY ACCESS

Worldwide Diagnostic System (WDS):

Special Tool(s)

NOTE:
- The security access procedure is used to obtain passive anti-theft system (PATS) security access. PATS security access must be granted to erase ignition keys, enable/disable unlimited key mode, enable/disable the spare key programming switch (PID SPARE_KEY), and carry out a parameter reset on the module. The security access procedure invokes an inherent 10-minute time delay prior to granting security access, during which time the diagnostic tool must remain connected to the vehicle. Once security access is granted, a security access command menu is displayed which offers various command options.
- Once security access is 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. Using the diagnostic tool, select instrument cluster or powertrain control module (IC or PCM) from the menu. Select SECURITY ACCESS. This procedure takes 10 minutes to carry out, during which time the ignition switch must be in the RUN position and the diagnostic 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 necessary before exiting from this menu. Once exited from this menu, the security access procedure must be repeated to carry out additional commands.
