Description
The Haldex EBS EB+ Gen 3 system, widely used on commercial trailers and heavy-duty vehicles, is known to suffer from internal air leaks and pressure sensor failures. These faults can compromise braking performance and trigger diagnostic warnings.
Common symptoms include:
-
Audible air leaks from the EBS control unit
-
Constant or intermittent brake warning lights
-
Loss of brake efficiency or uneven trailer braking
-
Fault codes relating to pressure sensor circuits, including:
-
Service line pressure transducer open circuit
-
Modulator 21 delivery pressure transducer open circuit
-
Reservoir pressure sensor open circuit
-
Suspension pressure sensor open circuit
-
These issues are typically caused by internal electrical or pneumatic faults within the EBS module, not external wiring or air system components. Left unresolved, these faults can lead to failed brake tests or trailer safety issues.
