The Jaltest JDC108A is the adapter cable for the Haldex EB+/TRS braking system and the Haldex TPMS tire pressure monitoring with the manufacturer-specific 4-pin connector; on the system side sits that connector, on the interface side the 16-pin OBD2 of your Jaltest diagnostic cable. The connection belongs to the Haldex control unit on the trailer chassis, so both systems connect through the same plug.

With this connection, the Jaltest equipment reads out both systems. With EB+/TRS, the coverage goes beyond reading: In addition to fault codes and measured values, you can control components and adjust parameters. With Haldex TPMS, it's limited to reading fault codes. Since trailers have never been required to have a standardized diagnostic connector, this plug remains in use on newer trailers as well. The cable falls under Jaltest CV (commercial vehicles).

KEY BENEFITS

✔Two systems with one cable: The EB+/TRS braking system and Haldex TPMS tire pressure monitoring.
✔With EB+/TRS, coverage extends beyond reading: Component control and parameter adjustment.
✔Chassis brand independent: The cable follows the Haldex control unit, not the trailer manufacturer.
✔No model year limit: Trailers have never had a mandatory diagnostic connection requirement.

IMPORTANT NOTES

✕With TPMS, coverage is limited to reading fault codes; don't expect component control or parameter adjustment.
✕For the 4-pin EB+/TRS connection only: Older Modal and Modular systems have their own connector (JDC101A and JDC102A).
✕Other Haldex systems — ABS MODAL, MODULAR/PLC, PLC Select, ITCM, U-ABS, EPV and the EB+ generations (2nd, 3rd and 4.0) — are listed as separate systems in coverage; check which connector is fitted to your unit.
✕Requires a Jaltest Link with valid CV license; the cable does not add coverage on its own.

Applications and features

Use this connection to access Haldex control units on the trailer with Jaltest software.

Control units you can access

  • EB+/TRS: The trailer brake control system this cable is designed for.
  • Haldex TPMS: Haldex tire pressure monitoring system.

What you can do

  • Read and clear fault codes: Access and clear the fault memory of the brake control unit after repairs.
  • View live data: Monitor real-time sensor readings from connected components.
  • Activate components: Directly trigger parts to test their operation.
  • Configure parameters: Read and adjust system settings.
  • For TPMS: Access tire pressure monitoring fault codes.

Compatible vehicles and applications

The connector type determines compatibility, not the model. This cable fits any semi-trailer or trailer with a Haldex EB+/TRS control unit or Haldex TPMS featuring a 4-pin diagnostic connector; verify which connector is installed on your chassis on-site.

Application:

  • Semi-trailers and trailers with a Haldex EB+/TRS control unit
  • Trailers with Haldex TPMS tire pressure monitoring
  • Chassis brand doesn't matter: The cable follows the Haldex control unit
  • Model year doesn't matter: Trailers have no mandatory diagnostic connector requirement
💡
Good to know: The diagnostic connector belongs to the Haldex control unit on the chassis. Haldex uses a different connector for each system generation. Therefore, check which connector is fitted to your vehicle before ordering.
