The connection between the electronic braking system (EBS) and the trailer is interrupted. What effect could this have on the trailer when braking?

When the electronic braking system (EBS) connection between the truck and trailer is interrupted, it affects how the trailer brakes. First, the trailer's anti-lock braking system (ABS) can be deactivated because it relies on electronic signals to function. Without this connection, ABS cannot prevent wheel lock-up on the trailer. Second, the trailer braking is still possible but depends on the pneumatic redundancy pressure—this is a backup air pressure system that ensures the trailer brakes are applied even if the electronic system fails. However, the brake lights remain functional through the vehicle's electrical system, so the statement about brake lights not working is incorrect. Understanding this helps ensure safe braking even if the electronic link to the trailer is lost.
