ABS DESCRIPTION

Description

The vehicle is fitted with an ABS braking system which prevents the wheels from locking during braking, makes the best possible use of the grip conditions available and keeps the vehicle as easy as possible to control during emergency braking.

The ABS is an additional section of the basic braking system; it is disabled if there is a problem, with the braking system working the same way as for a vehicle without ABS.

The advantage of ABS over conventional systems is that it makes it possible to maintain maximum manoeuvrability even when braking hard in poor grip conditions, preventing the wheels from locking.

The system is completed by the EBD system (Electronic Brake Distributor) which distributes the brake force by means of the ABS sensors and control unit.

The "ABS failure" warning light and the "minimum brake fluid level" warning light coming on simultaneously with the engine running means that there is a problem with the EBD system; in this case, the wheels could lock during sharp braking.

The "ABS failure" warning light coming on by itself with the engine running usually means that there is a problem with the ABS only.

In this case, the braking system will work properly, just without the anti-lock function.

The operation of the EBD system may also be affected under these circumstances.

If the "minimum brake fluid level" warning light only comes on, this means that the hydraulic system fluid level is too low.

On this version, the system is only available in the basic configuration.

If the vehicle in question is equipped with the ESP function and the additional TC/ASR, MBA/HBA and MSR functions,

The basic ABS system components are:

• the control unit
• four sensors which detect the rotation speed of each wheel (ABS sensors);
