The Jaltest JDC113.9 is the adapter cable that converts the proprietary 5-pin diagnostic connector from refrigeration units by Thermo King and Carrier to the 26-pin DB26 connection on the Jaltest Link. The connector is located directly on the refrigeration unit at the control module; since the cable connects straight to the Link's DB26 port, you won't need any additional adapter cables.
Once connected, Jaltest diagnostic software can access transport refrigeration systems from both manufacturers: Thermo King's Smart Reefer 2 and Smart Reefer 3 and Thermoguard TG-VI, plus Carrier units MAXIMA/ULTRA, VECTOR and VECTOR 1350. The equipment reads fault codes, live data and ECU information from these control systems; for the Carrier VECTOR 1350, maintenance data is also included. Since refrigeration units have never had a standardized diagnostic connector, both manufacturers use their own connector design for each unit generation. This cable falls under Jaltest CV (commercial vehicles).
KEY BENEFITS
IMPORTANT NOTES

Compatible vehicles and applications
The connector type is what matters, not the model. This cable fits any refrigerated trailer or reefer semi-trailer equipped with a Thermo King or Carrier cooling unit featuring a 5-pin diagnostic connector; check which connector is installed on your unit on-site.
Application:
- Refrigerated trailers and reefer semi-trailers with a Thermo King or Carrier cooling unit with 5-pin diagnostic connector
- Chassis brand is not a factor: The cable follows the cooling unit, not the trailer manufacturer
- Year of manufacture is not a factor: Cooling units have no mandatory diagnostic connector requirement
