What does it mean when the Passat's anti-theft system is activated?
1 Answers
Passat anti-theft system activation may be caused by issues such as a faulty body control module, signal interference around the vehicle, unmatched vehicle keys, or poor key quality. The solutions are as follows: Repairing the faulty body control module: When the body control module detects an internal fault, it will initiate diagnostic functions, displaying a fault indicator on the dashboard to alert the owner for maintenance. Specialized equipment can also be used to read data within the body control module to determine the fault based on the displayed fault codes and proceed with repairs. Re-matching the vehicle keys: If the anti-theft system activation is due to unmatched vehicle keys, it will be necessary to re-match the vehicle keys.
