Ktag Hardware Configuration Not Supported -

. It typically indicates a failure in communication or a mismatch between the hardware's physical state and the software's expected protocol. Common Causes Voltage Instability

This is one of the most frequent reasons. Standard 12V adapters often output less than the required voltage (e.g., 11.6V), which is not enough for some ECUs. Experienced users from CarTechnoloGY and OBD Express suggest using a stable power supply between 13V and 14V . ktag hardware configuration not supported
