Deutsch 9 pin, PLC adapter (Trailer)

Jaltest Deutsch 9 Pin PLC Adapter (Trailer) — JDC112A The Jaltest JDC112A is the PLC (Power Line Carrier) adapter cable for diagnosing commercial trailer ABS systems that use the J2497 Power Line Carrier protocol. At $360, this is one of the more specialized — and more valuable — cables in the Jaltest trailer diagnostics lineup. If you service commercial trailers that use PLC-based ABS communication (as opposed to the standard 7-pin or 9-pin data links), this cable is what makes Jaltest-based diagnostics possible on those units. What This Cable Does The J2497 Power Line Carrier protocol is used on trailers where ABS and other brake control data is transmitted over the power line rather than a dedicated data line. The JDC112A bridges that communication to the Jaltest Link interface: Protocol: Supports J2497 Power Line Carrier (PLC) communication standard Trailer-side connector: 7-pin Deutsch connector — connects to the trailer ABS system Jaltest-side connector: 9-pin connector — connects to the Jaltest Link diagnostic interface Part number: JDC112A Application: Commercial trailer ABS systems using J2497 PLC protocol Manufacturer: Cojali (Jaltest) Diagnostic Capabilities with Jaltest + JDC112A When connected via JDC112A through the Jaltest Diagnostics software, technicians can: Read and clear fault codes — access ABS system DTCs on PLC-equipped trailers Monitor live data — view wheel speed sensor readings, modulator status, system parameters in real time View ECU data — system configuration, part numbers, software versions Actuate components — test ABS modulators and other actuated components Compatible with Jaltest PLC Power Adapter — when the tractor is not running, the PLC Power Adapter can supply power to the trailer ABS system for bench-style diagnostics Who Needs This Cable Not every trailer shop needs this cable — but shops that encounter PLC-based trailer ABS systems regularly cannot do the job without it: Full-service trailer repair shops — PLC-equipped trailers are common in certain fleets; having this cable means you can diagnose them without turning away work Fleet maintenance operations running trailers with Haldex, Bendix, or Wabco PLC-based braking systems Roadside assistance providers — trailer ABS faults related to PLC communication are a common breakdown cause DOT inspection and brake certification shops — verify ABS function on PLC-equipped trailers Important Note on Custom Cable Kits Per the official Jaltest 2025 pricelist, the JDC112A is explicitly excluded from the Jaltest Custom Cable Kit (part 29600). This means you cannot substitute the JDC112A as one of your six custom kit cable selections — it must be ordered as a standalone cable. This reflects its specialized nature and higher price point compared to standard optional cables.
