Used Yanhua Digimaster 3 to do 2015 Range Rover Cluster Calibration, got errors ” (7F12) the subfunction is not supported”(image 1), “(1E20) adapter not found” (image 3).
This is how I operate Digimaster 3:
Tap Meter System -> Europe -> Land Rover -> Diagnostic socket adjustment -> Range Rover ->
Yanhua engineer solution:
Please use this CAN-OBD DM2 cable (contained in the package of Digimaster 3)
Good luck!
