SPECIAL TOOL CHART
| Worldwide Diagnostic System (WDS) Vehicle Communication Module (VCM) with appropriate adapters, or equivalent diagnostic tool |
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.
