For Tata-Daewoo vehicles with a non-standard wired 16-pin diagnostic connector, the Jaltest JDCOBD3 serves as the adapter to the 16-pin OBD2 diagnostic cable of the Jaltest Link. The unit measures 8.7 cm and comprises a sealed, screwed plastic housing with a 16-pin OBD2 connector with pins on the front; the diagnostic cable connects to the rear. The white label bears the designation JDCOBD3 written as one word, whilst the Hyundai version displays JDC OBD2 with a space.
In these vehicles, the diagnostic lines are positioned on different pins than the OBD2 standard specifies; the connector may fit physically, but no communication is established. The converter remaps the lines to the standardised positions, enabling the Jaltest Link to reach the control units behind that connector. You can then read fault codes, monitor live data and perform actuator tests. The adapter is specified for Link V8.1 and V9 and falls under the Jaltest CV module (commercial vehicles).
KEY BENEFITS
IMPORTANT NOTES
Applications and functionality
Using this converter, you can access the control units behind the diagnostic connector of your Tata-Daewoo vehicle via Jaltest software. The communication content remains unchanged; only the location of the diagnostic lines in the connector changes. What appears on screen depends on the Jaltest coverage for that vehicle.
Control units you can access
- The systems on the diagnostic connection: The Jaltest Link sees the same control units as on a vehicle with a standard wired connector.
- Which units those are: This varies by model and year of manufacture and is determined by Jaltest coverage, not by this article.
What you can do
- Read and clear fault codes: Current, permanent and intermittent codes with the original OE description.
- View live measurement values: Sensor and parameter values whilst the vehicle is running.
- Perform actuator tests: Direct control of components to verify operation.
- Maintenance and calibration: System-specific service and reset procedures, where Jaltest provides them for the vehicle.
Compatible vehicles and applications
The pin assignment is what matters, not the model. This converter belongs to the Tata-Daewoo version of the 16-pin connection. The badge on the cover tells you nothing about it, the wiring does; you can verify the points below on the vehicle itself before you decide.
Tata-Daewoo (scope):
- Connector type: The 16-pin OBD2 connection fits mechanically onto a standard OBD2 cable.
- Recognisable case: The cable clicks into place, but the Jaltest Link finds no control units; this indicates non-standard pin assignment.
- Out of scope: Vehicles whose 16-pin connection is wired according to the standard.
- Segment: Commercial vehicles, within the Jaltest CV module.
