Great Job once Again Mr Master Driveline. Question how would you set the scope up on a Digital ABS signal? I look on your chart which is not listed. Thanks a million
A digital ABS sensor is going to be hall effect or magneto resistive. I don't think I have a vehicle to test this on but I would start with the following settings. These are most likely a 5 volt circuit but they could also be up to 12 volts. Start with a voltage setting of 2V (lower it to 1V for a 5V circuit), set the time to 50ms and you may need to adjust it up or down based on the wheel speed and the amount you wish to view on the screen. Auto trigger, Trigger voltage around 1 volt, Trigger on the Rise, invert off, horizontal trigger 1 graduation from the left and meters set to frequency. Tweak these settings once your connected to the vehicle and the faster the wheel speed the higher the frequency. I will put this on my wish list to do. locate and back probe the trigger or signal wire from the sensor. There are only 2 or 3 wires so even if you are guessing and check each wire you can't hurt anything. The wheel should be rotating slowly when your probing the sensor wires. If you get this to work please write back with what settings worked for you.
