Description
OEM-Level Diagnostics for Caterpillar & Perkins Engines
Expand your diagnostic capabilities across heavy equipment and industrial diesels with the Jaltest JDC505A CAT & Perkins Diagnostic Adapter Cable. Engineered specifically by Cojali, this heavy-duty 9-pin adapter bridges proprietary engine diagnostic connectors (prior to CAT’s 14-pin style) directly to standard 16-pin OBD2 main diagnostic cables.
Whether servicing construction fleets, agricultural equipment, stationary power generators, or marine propulsion systems powered by CAT or Perkins engines, the JDC505A delivers reliable, high-speed communication to troubleshoot fault codes, calibrate systems, and perform essential maintenance.
