ANTI-LOCK
BRAKING
SYSTEM (ABS)
D. FAIL-SAFE FUNCTION
If the ABS system detects any fault that may
adversely affect its performance it will switch to a fail
safe shut down mode. When this happens the
electricity supply to the solenoid valves is
deactivated, stopping control signal output, this
causes the valves to switch to their default state.
(Open for inlet valves / Closed for Outlet valves)
The
System will light the relevant warning lamp at the
same time to inform the driver the vehicle has either
an ABS or an ABS and EBD failure.
In this condition, the conventional hydraulic brake
circuit will still function, allowing brake pressure to
reach all wheels. It should be noted that with an ABS
fault it will be possible to lock the wheels and in the
Case of an EBD failure the brake force proportioning
between front and rear will no longer function and
hence rear wheel lock is possible before front.
