I don't understand
ABS UNIT = pin39
Esc Button= ?? ( which pin. It is normally pin9-10)
I did not understand how a 1 cable going to ABS would work. ?
Thank you
Easy if you know electrical....
The switch has an "input" side & an "output" side...the live wire I connected to my EPB live supplies a "live" "input" for the switch, when you press the switch in "makes" the connection and sends this electrical signal down the "output" wire to the ABS unit...this tells the ABS unit that the switch has ben activated...
Quote from the first post in this thread:-
The ESC OFF button operates by sending a momentary 12V power supply to the ABS/ESC controller which trips the traction control off or on. All the button requires is any switched (powered on with ignition only) 12V supply & a connecting wire to the ABS/ESC controller. At the factory this is wired as a 12V supply coming from Fuse 34 (7.5A), in a Black/Yellow wire, to the switch (pin 10), & then a Purple/Green wire from the switch (pin 9) to the ABS/ESC controller going via pin5, connector T17d, at what VW call the “TIUL Coupling Point”.
So working back from the ABS unit:
pin 39 ABS unit to connector T17d pin 5..then from connector to pin 9 ESC switch...
Then pin 10 switch to a wire connected to fuse 34 (I used the EPB)
