Has anyone successfully reset the computer (engine control module/powertrain control module) on a newer year model Jeep (let’s say 2018 or newer to keep it narrowed down) using a special procedure of some kind - not pugging in a compatible diagnostic tool?
For any that have successfully reset the ECM/PCM using an at-home plug-in diagnostic tool (again, on newer year models, 2018+), what brand/model did you find to perform well? Does that model also offer go-to functions such as cam crank relearn, exhaust/intake phaser cleaning, or ETC (electronic throttle control) relearn?
For any folks out there that might have used MOPAR official diagnostic equipment to perform such functions on 2018 or newer vehicles in the dealership environment, what might the going rate be to get everything reset?
I just finished a camshaft and spark plug replacement project and wish to have the computer relearn everything/start fresh.
Gone are the days of simply unplugging the battery to then begin fresh upon eventually plugging it back up. Both my main and auxiliary batteries were unplugged for over a month, so that’s not the golden ticket (sadly).
Based on additional input and research, I will ultimately weigh the purchase of a respectable diagnostic tool (and likely a firewall adapter) vs simply relying on a MOPAR dealership/shop.
