Volvo construction 14 pins diagnostics cable

Jaltest Volvo Construction 14-Pin Diagnostics Cable (JDC509A)

The JDC509A is the genuine Cojali Jaltest diagnostic cable for Volvo construction equipment — a 14-pin cable that connects your Jaltest Link interface to Volvo CE machines for full ECU-level diagnostics through Jaltest OHW software. Volvo Construction Equipment is one of the explicitly featured brands in Jaltest's OHW coverage, and the JDC509A is the physical connection point that makes all those diagnostic capabilities accessible. Whether you are running fault code analysis on a Volvo excavator, monitoring live data on a wheel loader, or programming components on a Volvo articulated hauler, this cable is the required interface. It is also included in the Jaltest OHW USA Cable Kit, indicating its status as one of the core OHW cables.

The JDC509A connects the Jaltest Link interface to Volvo construction equipment via the 14-pin proprietary diagnostic connector used across the Volvo CE product line. Once connected, Jaltest OHW software provides comprehensive access to all supported Volvo CE ECUs.

Volvo CE Coverage in Jaltest OHW

Volvo is a marquee brand in Jaltest's OHW coverage — specifically called out alongside CAT and John Deere as a featured brand with dealer-level capabilities. The Jaltest OHW kit (part number 29211, $4,500 MSRP) covers all ECUs on off-highway equipment: engines, transmissions, aftertreatment, hydraulics, and body computer. Volvo CE machines run sophisticated electronic systems across all of those areas, and Jaltest provides access at a depth that would otherwise require proprietary Volvo factory tools (VCADS/PTT). The JDC509A is the required cable for that connection.

Who Needs This Cable

Construction equipment shops, equipment rental companies, Volvo CE dealers and independent service providers, public works operations with Volvo machines, and any shop running Jaltest OHW that services Volvo construction equipment. Coverage starts with 1999-model Volvo CE machines, which means the vast majority of machines currently in the field are within scope.
