Step 5: Testing the function of the brake pressure sensor and brake light
switch
Start the RaceABS with connection to the MSA Box II and press the brake pedal
for a few seconds with slowly rising pressure. The digital display “Brake
switch“ bit should toggle from 0 to 1, see screenshot below.

If the bit does not toggle, check the pressure sensors. The brake light switch bls
is a function of the pressure sensors.
The digital display „Pressure sensor“ should show a logical value, e.g. 3.87, in the
screenshot below.
