Gateway Module
A gateway module is located behind the TSD. The gateway module is the link component between the vehicle bus systems and the audio/telephone system MOST ring. When the vehicle is unlocked, the gateway module receives a system 'wake-up' message on the CAN bus. This message is then passed on the CAN bus from the gateway module to the integrated head unit which then 'wakes-up' the MOST ring components by energizing the infotainment relay. Refer to AUDIO SYSTEM COMPONENT LOCATION - FROM 2005 MY for further details on the gateway module.
