Description
Haldex trailer ABS and DIAG+ is the Haldex software for its anti-lock and electronic braking systems on commercial trailers.

What Haldex trailer ABS does for your workshop
The program reads stored faults, shows sensor values and runs supported setup and end-of-line tests. Therefore, it helps a trailer shop clear an ABS lamp and prove the brakes work before the trailer goes back on the road.
- Read and clear trailer ABS and EB+ faults
- Wheel-speed sensor and modulator checks
- Supported setup and end-of-line tests
- System information and odometer data where supported
For example, a trailer repair shop checks a sensor fault after a hub change.


About Haldex and its service software
Haldex is a Swedish supplier of brake and air suspension systems for trucks and trailers. Its trailer ABS and EBS systems store fault codes that a technician reads with Haldex diagnostic software. You can see every Haldex title we install on the Haldex software page. For the maker’s own information, visit the official Haldex website.
Haldex trailer ABS system requirements
Before you order, please check that your laptop meets these requirements. In short, a recent business laptop is enough, but an old or very slow computer will not run the software well.
- Windows 10 or Windows 11 Pro, 64-bit
- Intel Core i5 8th generation or newer (or a similar AMD processor)
- 8 GB of RAM or more
- SSD drive with at least 250 GB of free space; we install the software on drive C
- A Haldex-compatible diagnostic interface; tell us your interface and we confirm it before payment
- Internet access during the remote installation only; afterwards the software works offline
Not sure about your laptop or adapter? Send us its details before payment, and we will check it first. If we think the computer is too weak, we will tell you before you pay.
How we install Haldex trailer ABS for you
Installation is fully remote. First, you complete the order and pay by PayPal at checkout. Next, a technician contacts you by WhatsApp or email to set a time. Then we connect to your laptop with TeamViewer or AnyDesk, install the software, activate it and check that it opens correctly. A single program is usually ready the same day; a full pack can take several hours, depending on your internet speed.
Please keep the laptop plugged into its charger during the session. One licence covers one computer, so a second laptop needs a second installation. After the installation, do not update Windows or the software, because an update can break the activation.

Support, warranty and refund policy
Every installation comes with 12 months of support from the installation date. During that time, we reconnect and fix the program if it stops working. However, the warranty ends if you reset or reinstall Windows, or if you update Windows or the software.
Because we deliver the software digitally, you cannot return it like a physical product. You receive a full refund if you cancel before the installation starts, or if our technician cannot make the software work on the setup we confirmed with you in writing. However, we do not refund a change of mind after a working installation. Read the full refund and return policy and the delivery page for every detail.
