PCMTuner Failed to Write EDC17C84 via OBD?
Problem:
I have a problem with PCMTuner. I can read but can’t write EDC17c84 via OBD.
Solution:
Remove ECU and read/write again on bench module 71.
If the car does not start by module 71 bench mode, the problem can be the checksum.
After fixing the checksums, it works on bench module 71.
If not working, try unplugging the T° engine sensor and try if not successful Wait until T°10 and retry.
