Startup Checklist
This short checklist is intended to supplement the ABS M4 Kit’s manual, not re‐
place it. Prior to using this checklist the user/installer should read the ABS man‐
ual, especially section
Assembling the Parts [
}
18] to Laptop Communication
[
}
24] .
Basics
▪ Hydraulic unit with attached control unit mounted correctly (mounting plate
used, brake lines facing upwards), see section Hydraulic Power Unit with at‐
tached Control Unit [
}
18] .
▪ Brake pressure sensor and Yaw/Acceleration sensor installed in proper loca‐
tions? See section Brake Pressure Sensor [
}
19] and Gyro/Acceleration Sen‐
sor [
}
20] .
▪ Everything plugged in to harness, power ring terminals connected to battery,
ground ring terminals connected to solid and clean chassis ground, circuit
breakers installed properly, ABS toggle switch turns off system. See section
Brake Pressure Sensor [
}
19] and Gyro/Acceleration Sensor [
}
20] .
Software Tool and Error Checking
▪ Connect to the ABS M4 control unit with MSA Box II using RaceABS Software
and ensure that all vehicle data has been entered correctly. The vehicle data
can be saved and or loaded by right clicking in the screen.
Notice
Once the diagnosis software RaceABS is connected to the har-
ness, the ABS warning light (MIL) will light up and remain lit
until it is disconnected. See section
Testing [
}
30] , Step 2. If the
MSA Box II is not connected to the laptop, the indication lamp
illuminates yellow.
▪ With the system on, switch to the “ECU Info” page and clear errors with click‐
ing on Clear FPS. Wait a moment (system will self‐refresh error stack). Reset
the system by switching off/on. Check if any errors reappear in the error
stack. If errors reappear, diagnose errors before proceeding. If anything was
unplugged during the diagnostic process, errors will be present and need to
be removed from the error stack. Next, cycle ABS on/off switch and verify no
errors are present after cycling power, see section
ECU Info (Diagnostics)
[
}

Error Notes
▪ In case of use of a wheel speed signal splitter: If the wheel speed signal split‐
ter is disconnected, all four wheel speed sensors will have error entries.
