The smart junction box (SJB) receives voltage for the power locks on circuit 906 (RD/OG). The door lock actuators are powered through the SJB through fuse 3 (25A). The SJB energizes the luggage compartment release relay. The SJB energizes circuit 84 (VT/YE) when a command is received from the RKE transmitter, and releases the luggage compartment lid latch.
