Mercedes w221 S550 ABR ABS ESP N47-5 PCB fault diagnostics and fix 5905 5906. 

This is a very detailed video for measuring and checking normal devices. However, nothing is fixed here. The voltages shown on "bad" device are normal. Mine was exactly the same and the device tested good when removed from the circuit. Nice effort, but you didn't verify this took care of the error. If you actually solved the ABR ESP problem, please update what was done.
