ANTI LOCK BRAKING SYSTEM (ABS)

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.
