There was an error occurred when one customer used Yanhua Digimaster 3. Our engineer provided the relevant solution. If you also have the same problem, hope it helps you.
When i wanted to correct odometer on my car by Odometer Correction digimaster 3, a message prompted “Not find device” on the screen. I couldn’t do any mileage correction.
Yanhuaacdp.com engineer solution:
You didn’t weld the chip of the car odometer on the OBP adapter, the board you connected to digimaster 3 was empty so cannot find the device and read any info. Please remove the chip from the odometer and sold to the board, then try again.
