Maybe some pros can answer this question. @Brutal_HO @Jimmy07 @FM45
Toward the top of the log file/settings, there is a long list of settings under “ECU Qualification”. I have not changed any of these myself using AlfaOBD.
Here are some examples under this setting category that seem related to popular mods.
ECU Qualification:
Sense-Hood Ajar Switch: Yes
Sense-Liftgate/Trunk Ajar: No
Control-Trailer Tow: Yes
Control-VTA Indicator Request: No
Rain Sensor Present: No
Discussion:
1. Mod related to adding VTA (see #4 below). I appear to have the hood ajar switch from the factory (I assume) as if I pop the hood release the hood ajar indicator will show on the dash.
2. Mod—tailgate ajar. For the setting “Lift gate/Trunk Ajar”, I added the tailgate switch and harness, and changed the other required settings with AlfaOBD, and now I get an indicator on the dash when my tailgate is open. I did not update the related ECU Qualification setting, but it seems to work fine with this set to “No”.
3. Trailer tow—I had the dealer add this, it was not on my truck when purchased. I assume they updated this from “No” to “Yes” when added the sales code.
4. Vehicle Theft Alarm (VTA)—I am getting ready to perform this mod. None of the related threads note updating this setting as part of the mod.
5. Rain sense—I am also getting ready to perform this mod. None of the related threads note updating this as part of the mod.
Should these be updated with other related settings? “ECU Qualification” settings do not seem to be included in related threads even though they seem logically related.
What is the purpose of these ECU Qualification settings?
