Why Some Trailers Brake Smoothly While Others Donβt
Have you ever noticed that some trailers stop smoothly while others jerk or skid? The culprit is often the Electronic Braking System (EBS). Proper maintenance is essentialβbut understanding how EBS works can be complex. Thatβs where Jaltest CV, a complete technical platform, makes the process fast and reliable.
What Makes EBS Maintenance Unique
Maintaining a trailerβs EBS is like solving a puzzleβyou need the right tools, detailed instructions, and patience. The EBS controls braking through sensors, valves, and wiring. Even a small fault can lead to major safety issues.
With Jaltest CV, technicians can:
- Instantly read diagnostic trouble codes (DTCs)
- Access real-time technical data

- Follow step-by-step repair instructions
On average, a full EBS check takes 1 to 2 hours. Even complex systems become easy to manage with Jaltest.
How to Perform a Trailer EBS Diagnostic
- Connect Jaltest CV to the trailerβs diagnostic port.
- Launch the software and select the trailer brand and EBS type.
- Run an automatic scan to detect active or stored DTCs.
- Review fault descriptionsβJaltest explains each code and suggests likely causes.

- Use the electrical diagram to locate the affected sensors or valves.
- Follow the guided steps to test, measure, and reset components.
π‘ Tip: Only clear codes after confirming the repair to ensure the issue is fully resolved.
EBS System Reassembly and Testing
Once all components are checked:
- Reconnect all plugs and sensors properly
- Perform an EBS activation test to verify sensor and valve responses
- Check braking balance and response times
β Pro Tip: Save screenshots and reports for professional documentation and future tracking.
Fleet Maintenance and Storage Tips
For fleets, store vehicle profiles and diagnostic histories in Jaltest to speed up future checks. Protect sensors from moisture, and perform periodic diagnostics to prevent breakdowns in idle trailers.
