The Jaltest JDC309A is a specialist adapter cable, designed for diagnosing the modern ZF Ecolife automatic transmission in buses. This cable is specifically intended for versions equipped with a round 9-pin diagnostic port. It forms the indispensable bridge between this specific 9-pin connector of the transmission computer and the 16-pin OBD2 connector of your Jaltest system.

It is important to know that there are different diagnostic cables for the ZF Ecolife transmission. The JDC309A is the right choice when the bus has a 9-pin port, as opposed to the Mini-USB port which requires the JDC308A. Workshops servicing modern city buses should have both cables for full coverage. This cable guarantees a reliable, direct connection to the advanced Ecolife ECU for troubleshooting complex faults.


Application and functionality:

The main purpose of this cable is to enable a direct and in-depth diagnosis of the ZF Ecolife transmission ECU via the 9-pin port.

  • Direct transmission diagnosis: full access to the advanced Ecolife computer.
  • Reading and clearing fault codes: reading and deleting transmission and retarder-related fault codes.
  • Viewing live data: reading oil temperature, pressures, turbine speed, retarder status, and selected gear.
  • Calibrations and adjustments: resetting adaptation values of the clutches and performing calibrations after maintenance.
  • Component testing: checking the operation of specific shift valves (solenoids) and the retarder.

Suitable vehicles and applications:

Suitable for any bus or coach with a ZF Ecolife transmission with a 9-pin port.

  • Primary application: Diagnosis of ZF Ecolife transmissions.
  • Vehicle type: Buses (city and regional buses) and coaches.
  • Commonly used in:
    • VDL

  • Connector requirement: round 9-pin diagnostic port present. Note: some Ecolife systems use a Mini-USB connector (JDC308A).
