In modern commercial vehicle electronics, EBS systems (Electronic Braking Systems) are at the core of safety. The connection between EBS units (e.g. from Wabco, Knorr-Bremse, or Haldex) and peripheral devices such as a CAN-Bridge for tire pressure sensors (TPMS) places the highest demands on wiring.
Why a “standard cable” can not be used here — and which clever detail makes life easier for mechanics when the chassis has been painted over — is explained in this article.
Waterproofing to IP69K: Must for Safety
Since the EBS directly controls the braking performance of the vehicle, operational reliability is the top priority. A short circuit caused by moisture ingress must not occur under any circumstances.
High-quality EBS cables are characterized by the following features:
- Complete sealing: Cables and connectors are not loosely connected but firmly crimped together.
- Encapsulation: In a multi-stage process, the connection point is overmolded with plastic.
- IP69K standard: This design ensures protection against high-pressure cleaning and permanent moisture.
This level of sealing is essential both at the connection to the EBS unit and at the CAN-Bridge.

The “hidden” data matrix code: A practical solution
A problem that occasionally occurs in workshop practice: a vehicle chassis is completely repainted – including installed control units and cables. The result? Type plates and identification numbers are hidden under a thick layer of paint and are no longer readable.
Our solution is a laser-engraved data matrix code located beneath the connector.
- The principle: The code is positioned in an area that is covered by the HDSCS connector (recognizable by the yellow locking element) when plugged in.
- The advantage: Even if the entire control unit has been painted over, you only need to disconnect the connector. The area underneath remains paint-free, allowing the code to be scanned and the CAN-Bridge to be clearly identified.
Compatibility: Wabco, Knorr-Bremse & Haldex
Vehicle architecture varies depending on the manufacturer and model. Therefore, a well-designed cable range covers all common EBS manufacturers.
Available configurations include:
- Direct connections: Simple cables for directly connecting the CAN-Bridge to the EBS unit.
- Y-cables: For applications where additional devices, such as a display, are connected to the EBS alongside the CAN-Bridge.

FAQs
What Requirements Apply to EBS Cables in Trucks/Trailers?
What Does IP69K Mean for EBS Cables in Trucks and Why Is This Standard So Important?
Are All EBS Cables Automatically ADR-Approved for the Transport of Hazardous Goods?
No. Only specially certified cables meet ADR requirements for vehicles transporting hazardous goods (e.g. tankers, chemical transport vehicles). ADR cables feature reinforced sheath materials, increased temperature resistance, and tested flame retardancy. We offer ADR-approved cables – feel free to contact us for more information.
Why Is the Data Matrix Code on the TireCheck CAN-Bridge Placed Beneath the Connector?
How Does the Hidden Data Matrix Code Help with Painted Control Units?
The data matrix code protected beneath the connector enables:
- fast identification of the CAN-Bridge after painting
- clear assignment of serial numbers
This saves time in the workshop.
What Length Should EBS Cables Have in a Truck Chassis?
The optimal length depends on:
- chassis geometry
- installation position
- existing cable routing
Cables that are too long increase mechanical stress, while cables that are too short pose a safety risk. Vehicle manufacturers typically use lengths between 50 cm and 250 cm.
