Kia Optima: 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 DiagramThis 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
