Safety Information The ABS M4 Kit was developed for use by professionals and requires in‐depth knowledge of automobile technology and experience in motorsport. Using the system does not come without its risks.
With this, the driver can choose the best setting for his vehi‐ cle. Furthermore, the ABS M4 provides the opportunity to program two individu‐ al control settings for you vehicle. For calibration drives, the ABS function can be deactivated separately, whereby all ABS sensor signals are transmitted and pro‐...

You can switch off the ABS functions by switching to position 12. This can be very helpful, e.g. for calibration of the brake balance adjuster. All ABS sensor signals will still be communicated. Every older ABS M4 can be updated to this function. During warm‐up we recommend to choose position 12. Since soft‐...

MSA Box II ABS M4 communicates with your laptop via the MSA Box II. It has a USB connec‐ tion to the laptop and a motorsport connector to interface with the ABS M4 wire harness.
All ABS M4 data can be stored on a CAN‐compatible data logger. We recom‐ mend to use our C 70 data logger for storing and analyzing ABS M4 data. Bosch Motorsport provides a standardized CAN log in DBC format for analyzing recorded CAN data.
Secure the hy‐ draulic power unit to the assembly plate supplied with the ABS M4 Kit using the three M6x1 screw threads on the underside of the casing. To reduce vibration, rubber pads should be fitted between the assembly plate and the vehicle chassis.
Bosch Motorsport ABS M4 needs special edited wheel speed signals, which are supplied only from active speed sensors like e.g. from Bosch DF11‐family. These double hall sensors operate on the differential principle. The ABS M4 needs all Bosch Motorsport ABS M4 Manual...
You should therefore only use the speed sensors as supplied in the ABS M4 ‐Kit (see section ‐‐‐ MISSING LINK ‐‐‐). We can offer different DF11 versions on request for specific vehicle designs. Existing mounted wheel speed sensors can be tested and approved by us.
The included wiring harness is structured in such a way that the power supply to the ABS warning light (MIL) is branched off before the main switch for ABS M4 (terminal 30). This is the only way to ensure that the ABS warning light (MIL) is lit when ABS M4 is not working.

ECU Info (Diagnostics) Indication lamp When you turn on the ignition or the ABS M4, the ABS warning light (MIL) comes on briefly and then turns off again. This indicates the light's self‐testing process. If the ABS warning light (MIL) does NOT light up when you turn on the ignition or the ABS M4, you must establish the reason for this before taking any further action or before driving the vehicle.
Page 36
If the warning light (MIL) is illuminated PERMANENTLY when you turn on the ig‐ nition or the ABS M4, or while driving, there is a system error. Extract the sys‐ tem's internal error log to analyze the error. You can access the log by clicking on the “ECU Info”...
