Does the tyre diameter front to back need to the same for the Teves 2 ABS system to work?
Tested and swapped out all four sensors, all Ohm ratings read fine at the ecu plug, pump works fine, tried different ecus also.
Passes self test on startup, but light comes back on after a few hundred feet.
rear tyres are 255/40 18 front 225 4018 so are about an inch or so different in diameter.
