Hello everyone. I’ve been trying to recreate the device in this YouTube channel and forum. I have some of the information to make it but not all. I was wondering if some one can show me how to make the device. I have included the information I have. TIA.
The code is almost certainly trivial. All it looks to be doing is making the sensors think the wheels are turning, or not or how fast - that's the information perhaps you have.
Post it here.
Four plus years since that video; there prolly aren't too many ppl who want to take apart the ABS system even to the small extent needed.

From the second link you posted:
Parts list:
1 arduino
2 12V relays (to use their coil, or just find 2 similar coils)
2 push buttons
4 meters of lamp cord
A power bank and usb cable to feed the Arduino.
Then program the arduino to give the correct number of pulses on the front and the back sensor to simulate 30 km/h.
Whilst the front push button is pushed, interrupt the signal to the front coil 5 times per second for 1/10th of a second. Do the same for the rear push button.
As well as the parts shown in the parts list in post #3, you will need two transistors or MOSFETs to switch the relay coils, and two flyback diodes to connect across the relay coils.
Thank you so much. Can you send me an Amazon link to the other items you mentioned, that you recommend? And how to wire it up exactly?
This code
makes the wheels appear to be rotating and skidding, changing every 0.1 seconds.
If you press a button, that wheel's button goes immediately to skidding.
The time constants for the rotation speed of the wheel gives about 420 Hz for the pulse rate, check my maths... but also tell me the ABS sensor has
OK, it's officially too hot for this just now, but I did see the sensor is reading reluctor gear teeth, so to verify or correct the given code we'd need to also know how many teeth there are.
The code is straightforward and adjustable. it might benefit from a bit more compile time caculations and rely on some directly known manifest constants like speed, wheel diameter and number of reluctor teeth on the sensor wheel.
Fun.

Or …. Lot of systems allow a signal to the ECU to open the internal valves .
