Required technical information
1.1 General instructions for ABS
The ABS brake system is split diagonally. The brake servo as‐
sistance is provided pneumatically by the vacuum brake servo
unit.
Vehicles fitted with ABS do not have a mechanical brake pressure
regulator. Specifically matched software in the ABS control unit -
J104- regulates the brake pressure distribution on the rear axle.
Note
If the ABS hydraulic unit - N55- is damaged, the ABS control
♦
unit - J104- must be fully replaced with the ABS hydraulic unit
- N55- .
The ABS control unit - J104- can be separated from the ABS
♦
hydraulic unit - N55-
The hydraulic pump and the ABS hydraulic unit - N55- must
♦
not be separated from each other.
Faults in the ABS do not influence the brake system and servo
♦
assistance. The conventional braking system remains fully
functional even without ABS. There will be a change in braking
behaviour. After the ABS warning lamp comes on, the rear
wheels may lock prematurely during braking.
Arrangement of the ABS, left-hand drive vehicle
