Footwell Module (FRM)

The Footwell Module (FRM) monitors the hall sensors of the door contacts to determine if a door is open or closed. CAS2 indirectly obtains the door status information and uses the information to determine if an enable signal is to be provided to the JBE.

Signal Path: Door contact signals input to FRM; Door status signal from FRM to JBE via K-CAN then forwarded from JBE via K-Can to CAS2.
