Whether you are trying to clear an engine code the hard way, or reset your closed loop fuel values in your ECU, learning how to reset your G35 ECU can be very useful. The ECU reset process is one provided by Nissan, but you can always reset your ECU by disconnecting your battery.

To reset your G35 ECU via the battery, merely disconnect the negative terminal and then get back into the car and depress the brake pedal a few times. This will help drain what little power is stored in the ECU capacitors or any other electrical device. Leave battery disconnected for 10-15 seconds and then reconnect the battery to clear your OBDII trouble code.

  2. I also am unable to reset my ecu using either of these methods. I used to be able to perform the pedal dance very easily but I think I might have a wiring issue somewhere at this point. I’m getting p0226 p0223 p1224. Any suggestions?

  3. I have a question. Does changing the ecu affects shifting gears ? I’ve changed my ecu and now there is a delay in changing gears. What is the problem ?

    • If you own an automatic yes different tunes and adjustments in ECU can and will change how your vehicle shifts. That’s because Infinti / Nissan from the factory has a set idea on how they want your vehicle to shift and handle. Once you change the ECU, you change the output and how the vehicle processes air and fuel.
