2015 Legacy and Outback
Each Radar unit contains an internal control unit that processes information from the RF antenna
and controls alert decisions. The left and right rear Radar units are distinguished as Master (LH)
and Slave (RH). The Master and Slave Radar units are connected to each other via a private
CAN network where alert decisions are determined. The Master (LH) Radar unit communicates
with the Main CAN for necessary vehicle information and receives a direct input from the console
mounted SRVD "OFF" switch. Each Radar unit has direct control over its respective side mirror
LED indicator.
