how could i tell if my Wheel Speed Sensor is working? unplu the gps antenna and drive around?

that sounds the easiest way without drivinga far distance and waiting to see where you lose ur antenna recption... any easier ways?

If you're talking about the D3, I think you can go to the menu, and hit something like hardware info, then system status (connection status maybe?). In that screen, among other useful bits of data, is the VSS sensor status.

In that same "hardware" Screen, you will see one option called "Speed Pulse" The Speed Pulse number will increase as you are driving..

That is how you know if VSS is hooked up

thanks

If it has VDD like the D1 does, see if the acceleration setting or speedo will work. If not. Then nope.

vdd doesnt mean anything, it gets speed reading from voltage. my dynamics speedo on my z1 is dead on and my car doesnt have a speed sensor to hook up to
