The Jaltest JDC40AM2 is a power adapter specifically designed for diagnosing ABS systems on trailers. This adapter uses the 7-pin PLC (Power Line Carrier) J2497 standard connector. The primary purpose of this product is to supply the trailer's electronic control unit (ECU) with power from an external source, enabling diagnosis without the trailer needing to be connected to a tractor.

The adapter functions as an intermediary that connects the Jaltest diagnostic interface with the trailer's ABS system and simultaneously with an external battery. This allows a technician to perform a complete system diagnosis, including reading fault codes, activating components, and configuring parameters. This is especially useful for maintenance and repairs in the workshop on disconnected trailers.


Application and functionality:

This adapter is developed to ensure a stable power supply for diagnosing trailer ABS systems.

  • External power supply: Allows the trailer's ABS ECU to be powered via an external power source, such as a battery, enabling diagnosis without a tractor.
  • PLC compatibility: Supports the SAE J2497 Power Line Carrier (PLC) communication standard, which is used for communication between tractor and trailer.
  • Independent diagnosis: Enables workshops to perform diagnostics and repairs on trailers that are not connected, increasing efficiency.

Compatible vehicles and Application:

The JDC40AM2 power adapter is universally applicable to trailers equipped with a 7-pin J2497 PLC connection. This includes systems from the main manufacturers of trailer brake and ABS systems.

Compatible systems:

  • Systems from Haldex
  • Systems from Knorr-Bremse
  • Systems from Wabco

Important: Before purchasing the product, always check your vehicle's connection. This may vary by model and year of manufacture.
