The Jaltest MDC02 is the test cable connecting the green 4-pin EBS connector (two rows of two) of the Knorr-Bremse module in MAN commercial vehicles to the 16-pin OBD2-port on the Jaltest ETM. You connect it directly to the module, not to the vehicle's diagnostic connector.
With this connection, the Jaltest ETM establishes communication with the modulator itself, as if it were the control unit. This allows you to determine whether the component is genuinely faulty or if the fault lies in the wiring or control unit. In addition to this cable, you will need the ETM itself, with an ETM licence and an active CV or Modular software licence.
KEY BENEFITS

- Knorr-Bremse EBS modulators: Second and third generation.
- Knorr-Bremse trailer control modulators: The brake control modules for trailers.
- Inductive wheel speed sensors: The speed sensors from ABS and EBS systems.
- Brake pad wear sensors: The sensors that monitor brake pad thickness.
