Gen 3 swap question on o2 sensors grayed out ( can't edit)
Good evening fellas,
I'm in the process of doing a swap on a Colorado. I've hooked everything up (mostly).
I turned on the PCM and downloaded the pcm file using my hptuner software. I found the VAT
and disabled it, not problem. When I went over to the DTCs.... most of the 02 stuff in the "SES
enable" and "error mode" columns were grayed out. I can't seem to change it. The other stuff is
fine. I can click on the other DTCs and check and uncheck them.
Now the wiring harness I have... the rear O2 stuff is not incorporated or wired. Could the pcm
detected that they were not connected and decided to gray that stuff out?
Or is it as simple as I have not yet bought the credits to reload my edited file and doing that
will unlock those columns? it's weird though because I can go into other sections and edit stuff.
JUst not the o2 stuff.
:shrug:
