Relay Box: Description and Operation

Description

Network Configuration
The Network of the SJB(Smart Junction Box) consists of Low speed CAN as shown in the following figure.





Termination Resistor
The cluster has CAN termination resistor. It is possible that CAN termination resistor value is changed by number of CAN controller. The termination resistor value of the cluster is 510 Ohms.

Function

Function Requirements
The BCM controls IPS and relay on the SJB. For example, if BCM requests head lamp low beam control, then BCM requests related lamp control at one time.

Signal Flow Diagram
This chapter defines signal between SJB and peripheral electrical apparatus in the form of signal flow diagram. Control of the IPS and relay is required by BCM. Following figure expresses power source that is operating power condition
