I hope I don't lead you up the garden path, but here is my take on what I would do. Caveat: I an VERY new to the Syvecs software, but I can't see how you can do any harm here, so long as you don't CHANGE any assignments willy nilly.
I would go into SCal and open your map (configuration file) Scroll down the left hand column until near the bottom. You are looking for IO Configuration, then a sub menu of Pin Assignments. You need to see what inputs the wheel speed sensors are assigned with. Double click the Pin Assignments listing and it will open to show a long list. I think you will be looking at the A) Inputs listings, then find Vehicle Speed Sensors.
Depending if all four are being monitored you should see listed:
A) INPUTS: Vehicle Speed Sensor (Front Left Wheel) then the assigned input, say AN6 (5V/TH) blah blah
Each wheel speed sensor will be assigned its own input pin, so you will probably find four of them listed, say:
AN3, AN4, AN5 and AN6.
Note these assignments and then find then in the lower right screen listings. Double click on each of the listed AN inputs and the software should show a rendering of the outputs at the bottom of the screen. Either drive the car, or with it jacked up safely turn each wheel in turn and check the correct display shows the voltage change. I think you will have to spin the wheel fairly fast as they will be magnetic sensors that do not output as reliably at very slow triggering speeds like Hall effect sensors. You could also go the Gauge : Add and choose a suitable format for reading the sensors if a numeric display isn't to your liking.
There are probably faster ways to access this info, but if you are wanting to press on this *MAY* help you check them out. You can of course check their outputs with a `scope or a DVM as well, but that won't show you what the ecu itself is seeing. I hope it helps a bit. Let's see what the experts say though
