ABS (ABS : HYDRAULIC (E VERSION)) BR03–6
FUNCTION
EN0680103C100003
FAIL-SAFE FUNCTION
This ABS system is equipped with a fail-safe function that causes the ABS
warning light on the instrument panel to light and to restore the normal
(non-ABS) brake system, should an ABS malfunction occur.
Note that the ABS system consists of two independent circuits. Should a
malfunction occur for whatever reason in the electrical circuits, that sys-
tem's ABS is switched off and the normal brake system is restored while
ABS control continued for the other system. This configuration is designed
to minimize the effects of any malfunction on ABS function.
EXHAUST BRAKE CONTROL FUNCTION
The ABS of this vehicle is equipped with a function that controls the
exhaust brake while ABS is operating. If the exhaust brake is applied inde-
pendently or in conjunction with the service brake on a road surface with an
abnormally low friction coefficient, the drive wheels may lock. This ABS
prevents the drive wheels from locking in such situations by automatically
releasing the exhaust brake, if necessary, during ABS operation.
