Just uploaded a vid to youtube showing several functions on the 2010 Instrument cluster working
Just to get the Hazards to working on the later switch the GEM module & Instrument cluster is required, As GEM module will not work independently.
Basically the switch informs the GEM module that Hazard lights are requested, GEM send a signal via MS-CAN to instrutment cluster to instruct it to chime & Flash the teltale lights. Instrument cluster then sends a signal back to the GEM module via MS-CAN, to confirm instructions. Its the same communication process between GEM module & Instrument cluster for Air Recirculation switch, LH/RH indicators & doors.
