Error log
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” tab in the RaceABS software.
Fig. 1: You’ll find a complete overview of error log entries in an Excel sheet on the ABS M5
product side at www.bosch‐motorsport.com.

Notice
System reset after drive cycle defaults.
Drive cycle defaults, e.g. because of wheel speed sensor bug,
need an ABS-ECU reset (Power off - Power on). After the reset,
the car has to accelerate to more than 12 km/h for system
check.
