Lets start over . . . .
I just spent over 2 hour setting on the bottom of a mud bucket going through the SCT 3015 programming.
Here is the sequence of events:
Program Vehicle - select
Custom Tune - select
Adjust Additional options - no - select
Program with Custom Tune - select
Begin Program
Error 1019 - Unlock ECM failed
Download failed - turn key off -
I did this several times and am now convinced that the tuner device is not uploading the tune at all and never has. I did this with and without the PATS module. Back to pin out continuity testing.
The Data Port communicates between the PCM and multiple OBDII tools including the SCT device. There are only 6 wires to deal with, 2 ground, 2 data buss, a 'hot at all times' B+ and the a 'Reprogramming Power Supply'. The Data Link + and - connections must be valid as they read from the PCM. There is permanent B+ on the Data Port connector pin 16 as it should be. That leaves only one wire . . . the 'Reprogram Power Supply'. Now that seems like a likely candidate for a screw up! I have verified that the pin 13 of the Data Port connector is, indeed connected to pin 13 of C202, the PCM connector.
Had a moment of serious concern when I discovered that the pin 13 wire (violet) had a twin violet wire associated with the AC controls to the PCM. Fortunately, even a blind pig will find a acorn occasionally and I had used the correct violet wire.
Upload of the custom tune still fails consistently.
