How to Permanently Disable the Start-Stop Technology in Civic?
2 Answers
The method to permanently disable the start-stop technology in Civic is: connect an external device through the OBD interface and change the setting to default off or disable, or you can go to a 4S store for setting. Taking the 2021 Civic as an example, it belongs to the compact car category, with body dimensions of: length 4517mm, width 1799mm, height 1434mm, wheelbase 2700mm, front track 1547mm, rear track 1563mm, and fuel tank capacity 47l. The 2021 Civic is equipped with a 1.5l turbocharged engine, with a maximum horsepower of 177ps, maximum power of 130kw, maximum torque of 220nm, and matched with a continuously variable transmission.
The start-stop function on the Civic is indeed quite annoying. It keeps shutting off and restarting in traffic, which distracts me. To permanently disable it, you'd need professional equipment to reprogram the engine control module (ECU), like using an OBD tool at a tuning shop to connect to a computer and adjust the settings. But doing this might void the warranty or cause electronic issues, which isn’t worth the risk. I’ve gotten used to manually turning it off by pressing the OFF button every time I start the car—just hold it for a few seconds, and it stays off for that drive. If you really want a permanent fix, you can search for reliable tuning shops or Civic forums for tutorials, but the risk is on you. Messing with car electronics can easily lead to errors, so it’s best not to take unnecessary risks. Keeping it stock is the safest choice.
