Figure 16. WS compatibility

GADG1307171134PS

Three level current

WSx pin

(VDA compliant sensor

with Manchester encoded

information)

Data and diagnostic by SPI: Three level sensors have eight data bits and a parity bit which are written into the register upon

receiving. At higher speeds not all bits can be transmitted The data register for each wheel contains the number of data bits

received between two speed pulses

Two level current

(Standard compliant sensor

with only speed information)

Two level current PWM

(One pulse per tooth with data

encoded in pulse width)

(Two pulse per tooth with

data and diagnostic encoded
