Would any one know what the measuring block groups 01 thru 03 indicate in the ABS brake controller?

01 & 02 show the wheel speeds as each has 4 km/h elements but at rest 01 shows zeros and 02 shows 255s. But why two groups?

Group 3 again has 4 elements but with no titles and showing, ON, OFF, Not Operational & I've also seen Activated. Does anyone have a clue what these are?

Have attached a cut and paste of the log in case it helps.View attachment VCDS ABS Controller log.pdf

Cheers,

I've managed to find out a couple of things. Measuring block 01 shows the wheel speed in the following order, front left, front right, rear left & rear right with block 02 showing the start speed of the wheels i.e. the first speed for which a signal was registered, in the same order.

And the first column in block 03 shows the state of the brake light switch, Not Operational & Activated (doh!), but I still haven't got a clue what the remaining three are.

Not the most thrilling topic I admit but might be useful for someone...
