Doosan diagnostics cable new (note: JDC100 is needed to use this cable with the V9 link)

Jaltest JDC545.9 Doosan Diagnostics Cable (New Version)

The JDC545.9 is the current-generation Cojali Jaltest diagnostic cable for Doosan heavy equipment. If you work on Doosan excavators, wheel loaders, or other Doosan construction machines, this is the cable that connects your Jaltest system to the machine's ECU for full diagnostic access. The .9 designation identifies it as a V9-compatible design.

What This Cable Does

Connect the JDC545.9 between the Doosan machine's diagnostic port and your Jaltest Link. Jaltest software then communicates with the Doosan ECU to read and clear fault codes, stream live operating data, and perform supported calibrations and resets. This replaces any older Doosan cable in the Jaltest lineup and is the current recommended version for Doosan coverage.

Key Specifications

• Part Number: JDC545.9
• Compatible Equipment: Doosan heavy equipment (2006 and newer)
• Jaltest Link Compatibility: V8.1 and V9
• Important Note: JDC100 extension cable is required when using with the Jaltest Link V9

The JDC100 Requirement

V9 Link users must pair this cable with the JDC100 extension (sold separately). This is standard for several Jaltest specialty cables. If you are on V8.1, you can connect directly. If you are on V9 and do not already have the JDC100, order it alongside the JDC545.9.

Who Needs This Cable

Construction shops, equipment dealers, and fleet maintenance operations running Doosan machinery need this cable to use Jaltest for Doosan diagnostics. Doosan is a major manufacturer of excavators, wheel loaders, and compact equipment — if those machines pass through your service bays, the JDC545.9 is a required addition to your Jaltest cable set.
