Control Modules For Interior Lighting: Notes

The "interior lighting" function is distributed over several control module that communicate with each other via the K-CAN.

• Footwell Module (FRM) is responsible for switching the interior lighting on & off.
• Roof Functions Center (FZD) is responsible for the interior lighting components in the roof area.
• Junction Box Electronics Control Module (JBE) is the interface to the luggage & glove compartment lighting.
• Car Access System 2 (CAS2) receives the unlock signal and sends the instructions through the footwell module to switch on the interior lighting.

The interaction of these three control units is described in more detail on the following pages.
