The Jaltest JDC501A is an Adapter Cable designed to establish a connection between the specific 3-pin diagnostic connector of Steyr engines and a standard 16-pin OBD2 diagnostic interface. This cable is developed for performing diagnostic tasks on Internal combustion engines equipped with this specific connector, such as those found in off-highway and stationary applications.
The cable enables communication between the diagnostic device and the engine's electronic control unit (ECU). This allows the user to read and clear fault codes, view live sensor data, check system parameters, and perform other advanced diagnostic functions supported by the Jaltest software.
Application and functionality:
The JDC501A cable is specifically intended for connecting diagnostic equipment with Steyr engines. The functionality includes:
- Diagnosis and communication: Enables establishing a stable communication line with the engine ECU for reading and clearing diagnostic trouble codes (DTC's).
- System analysis: Provides access to real-time data, such as engine speed, temperatures, and sensor values, for a detailed analysis of engine performance.
- Connectivity: Forms a physical bridge between the proprietary 3-pins connector of the vehicle and the universal 16-pins OBD2 port of the diagnostic device.
Compatible vehicles and applications:
This Adapter Cable is compatible with machines and systems equipped with an Internal combustion engine from Steyr and provided with the corresponding 3-pins diagnostic port.
Steyr Motors:
- Off-Highway (OHW) vehicles: Applicable to various agricultural and construction machines.
- Stationary Engines: Suitable for stationary engines, such as generators and industrial drive systems.
