Anti-lock brake<br />

system (ABS) and antilock<br />

brake system<br />

with electronic<br />

differential lock<br />

(ABS/EDL) ITT Mark 20<br />

IE<br />

General<br />

ABS layout<br />

The ABS or ABS/EDL brake system<br />

is divided diagonally. Brake pedal<br />

pressure is assisted pneumatically<br />

by the vacuum brake booster.<br />

Vehicles with ITT Mark 20 IE ABS do<br />

not have a mechanical brake<br />

pressure regulator. Specially<br />

matched software in the control<br />

module controls the rear axle brake<br />

pressure regulation.<br />

Malfunctions of the ABS or ABS/EDL<br />

systems do not influence the brake<br />

system or the vacuum assistance.<br />

The conventional braking system<br />

remains functional even if the ABS is<br />

not operating.<br />

The hydraulic unit -a- and the control<br />

module part -b- form one<br />

component. Separating the two parts<br />

is only possible when the complete<br />

component has been removed from<br />

the vehicle.<br />

New control modules (replacement<br />

parts) are not coded and must be<br />

coded after installation.<br />
