cat sys on 2002 Jaguar S-Type

i have a reading of cat sys and my car turns off or loses power, could this be the catalytic converter, i do not have a owners manual so i can not look up the code.

CATS system stands for Computer Active Technology Suspension If sensors at the left front suspension strut tower are disconnected for any reason and the ignition key is turned on or if the sensors fail that display message will be displayed. There are only about 4 aftermarket scan tools that can read and deal with Jaguars in a meaningful way.
