Exterior Lighting

EXTERIOR LIGHTING

NOTE: The smart junction box (SJB) must be reconfigured before installing a new module.

The SJB controls the front and rear portion of the vehicle. This system relies on the controller area network (CAN) 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 CAN communication network to another module.
- which module controls the output of the feature.

Exterior Lighting
The exterior lighting outputs are controlled by the SJB.
