I used Foxflash ecu programmer to do SID309 OBD password unlock stop at 57%. I waited for 20 minutes and nothing was happening. How to continue?
eobdtool.co.uk engineer replied:
When reading password via OBD (IN CAR), please ensure IMMO system does not become active during find process. The password will be stored, even with the error, check the content of the file with hexeditor to see if contains data.
You must read password with ECU in vehicle.
Thank you, immo is the problem…
By the way, you were right, and the file is “empty”.
