Outback [Legacy] AWD F4-2.5L DOHC (1996)
Wheel Speed Sensor: Description and Operation
ABS
FEATURE
-
The ABS (Anti-lock brake system) electrically controls brake fluid pressure to prevent wheel "lock" during braking on slippery road surfaces,
thereby improving directional/steering stability as well as shortening the braking distance.
-
If the ABS becomes inoperative, the fail-safe system activates to ensure it acts as a conventional brake system. The warning light also comes on to
indicate that the ABS is malfunctioning.
-
The front-and-rear wheels utilize a 4-sensor, 4-channel control design: the front wheels have an independent control design*l and the rear wheels
have a select low control design*2
*1: A system which independently controls fluid pressure to left and right front wheels.
*2: A system which provides the same fluid pressure control for the two rear wheels if either wheel starts to "lock."
