You should have one tjts1, on your Foxwell menu anyway since its the same as mine.

I dont have the unit available now but its under the Controls menu I think..how does it go? Engine/Trans/Chassis/body/Controls/suspension... One getsunder controls, the units including the three SAM units and various components and then there is a "special vehicle control module" I have this and the readout is cannot communicate with the SVCM..And it reads out this special vehicle... I do find this unit for sale and various details, photos, but nothing describing its function. Just that its different for a taxi or police car or ...So I suspect something Nav related perhaps?
