The OBDSTAR M002A is a mass cable with battery clamp on one side and a connection on the Ground inputfrom your OBDSTAR device to the other. The clamp connects to the negative terminal of the battery or to a suitable earth point on the vehicle.

The cable is designed to establish a stable ground reference during diagnostic and programming work. By bringing the device and vehicle to the same zero potential, voltage fluctuations and signal interference during read and write operations are minimised. The M002AThe M002A is a supplementary accessory, not a power source or data connection: it provides earthing only. Which procedures you can perform depends on the software of your own device.

KEY FEATURES

✔Stable mass reference— the device and vehicle share the same ground potential during read and write operations.
✔Direct clamp connection— the robust clamp connects directly to the battery terminal or earth point.
✔Reduced risk of signal interference— a secure earth connection minimises interference during critical write operations.
✔Suitable for bench work — also usable when working outside the vehicle and an external earth connection is required.

IMPORTANT NOTES

✕No substitute for a power cable— the cable provides earth only; you will need a separate power cable for the current supply.
✕Only at a GND input— your OBDSTAR device must have this connection, otherwise you will not be able to use the cable.
✕Exclusively for OBDSTAR equipment— this cable is an OBDSTAR accessory and is not intended for use with equipment from other manufacturers.
✕Does not add vehicle coverage— earthing does not change the models and functions that your device supports.

Applications and features

The cable provides the earth connection between the device and the vehicle.

Control units you can reach

  • No — mass cable only: The cable does not communicate with control modules; it establishes an electrical reference.
  • GND input of the device: The connection point where zero potential is supplied.

What you can do

  • Connect the ground cable: Establish a direct GND connection between the battery or ground point and the OBDSTAR device.
  • Secure reference voltage: Provide the device with a stable zero potential for accurate signal processing.
  • Support bench work: Offer an external ground point to the setup outside the vehicle.
  • Minimise interference: Reduce the risk of signal distortion during read and write operations.
  • Important: The cable is an aid to connection; capabilities remain determined by your OBDSTAR device.

Compatible vehicles and applications

The GND input of your device is what matters, not the vehicle model. The source lists no makes or model years: the clamp connects to the negative terminal or a ground point and is therefore make-independent.

  • Vehicles with 12V battery or suitable ground point: That is where the clamp is attached.
  • OBDSTAR equipment with GND input: The device-side connector fits only that connection.
💡
Good to know: Attach the clamp to a clean and undamaged contact point: dirt or corrosion on the negative terminal or ground point will degrade the reference precisely during critical write operations. Verify before ordering that your OBDSTAR device has a separate GND input.
