To read/write a BMW cas4 with Xtool A80 pro (H6 PRO) with kc501, please solder correct follow the picture:
- 1.Remove the components in this Red frame area before the operation, do not discard them!solder back after the operation is complete
- 2.In order to read and write data stably,do not extend the connecting cable
Note:If it has poor welding and then re-solder it again, finally we can read and write the data successfully.
Hope it helps
