CONNECTING UP THE BRAKE LINES OF A TRAILER WITH ABS OR EBS
ABS: Anti-lock Braking System
EBS: Electronically controlled Braking System
A trailer with ABS is fitted with an anti-lock braking system.
A trailer with EBS is fitted with an electronically controlled braking system, which
incorporates ABS.
Both versions are connected by means of a special plug to the extra socket of the
ABS/EBS system on the prime mover.
If this plug is not connected, a yellow warning will appear on the master display.
