GLOVEBOX Switch Operation
WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
The central junction box (CJB) provides a battery voltage supply to the switch via the delayed power off relay. When the glovebox switch is pressed, the voltage signal is passed to the CJB . If the correct conditions exist then the CJB then provides a power supply to operate the glovebox latch to unlock the glovebox.
The glove box opening is inhibited by the CJB if the anti-theft alarm system is armed and if valet mode is selected using the Touch Screen Display (TSD). The CJB detects the voltage signal from the switch but will not operate the glovebox latch if other condition exists.
