The Jaltest JDC305A is a diagnostic adapter cable that establishes a connection between the specific 18+18-pin Knorr-Bremse ABS/EBS diagnostic port of a commercial vehicle and a universal 16-pin OBD2 diagnostic device. This cable is designed to enable communication with the electronic control units of braking systems.
This cable is developed for performing diagnostics, calibrations, and parameter settings on electronic braking systems (EBS) and anti-lock braking systems (ABS) of the Knorr-Bremse brand. It is applied to heavy commercial vehicles such as trucks, trailers, and buses equipped with this specific system.
Application and functionality:
This adapter cable enables communication between a compatible diagnostic device and the control unit of Knorr-Bremse braking systems to perform various tasks.
- Brake system diagnostics: Allows reading and clearing fault codes (DTCs) from Knorr-Bremse ABS and EBS modules.
- Live data display: Supports displaying real-time sensor data, such as wheel speeds, system pressure, and modulator status.
- Component activation and calibration: Provides access to functions for testing components and performing calibrations, depending on the diagnostic software used.
Compatible vehicles and applications:
The JDC305A is specifically intended for commercial vehicles and trailers equipped with a Knorr-Bremse ABS/EBS system using the 18+18-pin diagnostic port. Compatibility is system-specific, not brand-specific. This connection is found on vehicles from the following manufacturers, among others:
