The electric connections to your towing vehicle are interrupted. What device on the trailer is therefore rendered inoperable?

Your selected combination of answers is correct because both the anti-lock braking system (ABS) and the electronic braking system (EBS) on the trailer rely on electrical connections for their operation. When these connections are interrupted, both systems become inoperable, which is critical for maintaining safe braking performance.

Under German traffic regulations, it is essential that trailers equipped with these systems have functioning ABS and EBS to prevent skidding and ensure effective braking under various conditions. Thus, understanding the importance of electrical connections in ensuring the functionality of these systems is vital for safe towing practices.
