Anti-Theft System

The anti-theft device is created to deter criminals from stealing Jaguars. It employs a technique called Ultra Wideband to detect and verify the key fob's signal. This stops relay attacks, which can intercept the signal used for unlocking or starting the car even if the key isn't in the ignition.

Diagnostic tools, such as scanners are used to read the diagnostic trouble codes of the anti-theft control modules and also check for real-time data and freeze frame.
