NOTE: The smart junction box (SJB) must be reconfigured before installing a new module. Refer to MODULE COMMUNICATIONS NETWORK .

The SJB controls the front and rear portion of the vehicle. This system relies on the standard corporate protocol (SCP) communication network in order to transmit and receive signals. It is very important to understand:

where the input (command) originates from.
all information (messages) necessary in order for a feature to operate.
which module(s) receive(s) the input or command message.
if the module which received the input (message) controls the output of the feature, or does it output a message over the SCP communication network to another module.
which module controls the output of the feature.
