av318 Posted April 28, 2008 Report Share Posted April 28, 2008 Installing my system (N4) now and am pretty sure I found the VSS wire without problem. If I want to check to be sure I have the right wire how can I check it with my multimeter? I have a good Fluke and know how to use it. Not sure what type of variable input I'm looking for. Is it 0-20ma, 0-10v, or what? Quote Link to post Share on other sites
audiofreak19 Posted May 17, 2008 Report Share Posted May 17, 2008 i believe you put it on ac (alternating curent) and as you hit the gas on the multimeter it should go up and down as you hit the gas. Quote Link to post Share on other sites
inferno999 Posted May 17, 2008 Report Share Posted May 17, 2008 AC might work. Didn't think of that when I did mine. I did mine on DC. Put the car in neutral on a VERY gradual slope. One pin on Ground, other on what I thought was VSS. As I let the car slowly roll forward, the voltage went from 0 to 5v to 0 to 5v back and forth. This is consistent with the trigger mechanism in the VSS circuitry. Worked correctly upon install. Quote Link to post Share on other sites

jimmy303 Posted August 25, 2008 Report Share Posted August 25, 2008 Your VSS will be an AC signal, cycling from + to -. Voltage change can be anywhere from 2-3 volts, to 10-12 volts, depending on the vehicle. Quote Link to post Share on other sites
