Are you looking to reset the ECU in your 2006 Infiniti M35? Whether you’ve just performed some maintenance, installed new parts, or are simply looking to optimize your vehicle’s performance, resetting the Engine Control Unit (ECU) can be a beneficial step. This process allows your car to relearn driving habits and adjust settings for potentially improved fuel efficiency and smoother operation. While the original poster in the forum discussed ECU reset after a plenum spacer install, the general principle applies to various situations where your car’s computer needs to recalibrate.
One of the most common and efficient methods to perform a 2006 Infiniti M35 ECU reset is by using an OBD2 scanner. These scanners are readily available and provide a straightforward way to communicate with your vehicle’s computer system. To reset your ECU using an OBD2 scanner, you would typically connect the scanner to the OBD2 port located beneath your steering wheel. Once connected and powered on, navigate to the menu options that usually include “trouble codes”, “diagnostic functions”, or “service reset”. Within these menus, you should find an option to “reset ECU” or “clear codes”. Following the scanner’s prompts will initiate the ECU reset process.

Another method, though less precise, that’s sometimes mentioned involves disconnecting the negative battery terminal. While this can clear some ECU memory, it’s not always as effective as an OBD2 reset and may not clear all adaptive learning. If you choose this method, ensure your vehicle is completely off, and disconnect the negative terminal for about 15-30 minutes before reconnecting it.
After performing a 2006 Infiniti M35 ECU reset using OBD2 or the battery disconnect method, it’s recommended to allow your car to idle for a few minutes and then take it for a short drive. This allows the ECU to begin relearning your driving patterns and adjust engine parameters accordingly. As the original forum post mentioned, resetting the ECU can potentially improve MPG as the car optimizes fuel delivery based on current conditions and driving style.
In conclusion, resetting your 2006 Infiniti M35 ECU, particularly using an OBD2 scanner, is a process that can contribute to better vehicle performance and fuel efficiency. While simple modifications like a plenum spacer, as mentioned in the original post, might necessitate a reset, it’s also a useful maintenance step in other scenarios. Always consult your vehicle’s manual or a professional mechanic for specific guidance related to your Infiniti M35.
