anti-lock brake off switch/diff lock bypass

[alan cordeiro]

Since the ABS system has direct feedback from FOUR wheel sensors,
it does not need the speedometer hall effect sender signal
to know how fast the vehicle is going.......

The accelerometer is used to correlate wheel speed change
with vehicle velocity (deceleration) change.
