Wheel Speed Signal Splitter
The ABS M4 from Bosch Motorsport relies on specifically‐designed wheel speed
signals, delivered exclusively from active speed sensors, e.g. from the Bosch DF11
family. These sensors are used in current ABS and ESP® systems. The four speed
sensors included in the ABS M4 Kit meet this classification. The signal of a regular
speed sensor, as found in older series production ABS applications, is not com‐
patible with ABS M4; they could not be used as signal providers. It is an "open
collector" signal which grounds the voltage at the ECU input with every flank.
Bosch Motorsport has developed a wheel speed signal splitter that converts the
sensor signals in such a way that they can be processed by peripheral ECUs and
data recording systems. This signal splitter is available e.g. for measuring vehicle
speed or traction control. The signals of the different wheel speed signal splitters:

with 1 motorsport connector
The wheel speed signal splitter with 1 connector cannot be
used with the standard wiring loom design without changes in
the layout.
