Doosan DL03 engines in Bobcat diagnostics cable

Jaltest JDC547A Doosan DL03 Engines in Bobcat Diagnostics Cable

The JDC547A is a specialized Cojali Jaltest diagnostic cable for Doosan DL03 engines installed in Bobcat construction equipment. This is not a general-purpose Doosan cable — it is specifically engineered for the DL03 engine variant as configured in Bobcat machines, where the diagnostic connector layout differs from standalone Doosan equipment.

What This Cable Does

Bobcat uses the Doosan DL03 engine in several of its compact equipment lines. The DL03's diagnostic port in a Bobcat machine requires this specific cable for Jaltest to establish communication. Once connected, you can read and clear engine fault codes, view live data (RPM, temperatures, pressures, fuel system parameters), and perform supported diagnostic routines through the Jaltest software.

Key Specifications

• Part Number: JDC547A
• Compatible Equipment: Bobcat construction equipment with Doosan DL03 engines
• Jaltest Link Compatibility: V8.1 and V9
• Cable Length: Approximately 11 inches
• MSRP: 5.00 (Cojali USA 2025)

Why This Is a Separate Cable

Doosan makes engines used in their own branded equipment and as OEM powerplants in other manufacturers' machines. The connector and wiring configuration in a Bobcat differs from a Doosan-branded excavator. The JDC547A handles the Bobcat-specific DL03 installation. If you work on both Doosan-branded equipment and Bobcat machines with DL03 engines, you likely need both this cable and the JDC545.9.

Who Needs This Cable

Bobcat dealers and service shops, compact equipment rental operations, and general construction equipment technicians who encounter Bobcat machines with DL03 engines. If Jaltest is your diagnostic platform and Bobcat machines pass through your shop, this cable completes your coverage for the DL03 engine system.
