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 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

Multi Fuse

Multi Fuse is for optimizing the engine room package.
