I am using the Nissan Data Scan app with an ELM obdii Bluetooth adapter, the car’s 2000 Maxima GLE.
In order to make the Idle Air Volume Relearn stick using any of those apps and Bluetooth adapters, you can’t wipe any pending codes before/after Relearn is performed; for some reason when you use a third party app instead of Nissan Consult, it’ll write the changes onto the same partition as the error codes. What that means is you’re gonna write the IAVR over any pending existing codes in order to make it stay.
1. Don’t wipe any codes or clear the SES light
2. Perform idle air volume relearn
It’ll stay on your ECU as long as there is a pending code or the SES light is on. Once you clear the code and the SES light, your idle air relearn goes away as well. If you clear your codes and then do the relearn, your relearn will get overwritten once the code comes back. If you do the relearn with a pending code, it’ll stay there along with the code.
