How to Permanently Deactivate the Start-Stop Function in the Honda Avancier?

The method to permanently deactivate the start-stop function in the Honda Avancier is: 1. Start the car and let the engine temperature rise to around 35 degrees; 2. Press and hold the engine start-stop deactivation icon until the small yellow bar disappears, then release. Taking the 2020 Honda Avancier as an example, it is a mid-size SUV with body dimensions of: length 4585mm, width 1942mm, height 1670mm, wheelbase of 2820mm, trunk capacity of 510l, and a curb weight of 1708kg. The 2020 Honda Avancier is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 193PS, maximum power of 142kW, maximum torque of 243Nm, paired with a CVT transmission.

I drive a Honda Avancier, and the auto start-stop system is really annoying. I want to permanently disable it. Some people install devices through the OBD port, like buying an auto start-stop eliminator to trick the computer into not working. However, this method might affect battery life since frequent start-stop cycles require strong electrical support. Additionally, flashing the ECU software is more thorough, but dealerships don’t offer this service. Doing it privately could void the warranty and might trigger electronic control system failures. Safety-wise, it doesn’t save fuel but adds trouble, and in case of an accident, it’s hard to say. I suggest first checking the battery health—an aging battery makes the start-stop system more sensitive. Just press the button to turn it off every time you start the car; forming this habit is much better than hard modifications and can save repair costs. Also, vehicle inspections check for modifications, so don’t risk big losses for small gains.

I've been using my Honda Avancier for a few years, and the auto start-stop feature is really annoying. Some owners opt for convenience by purchasing auto start-stop deactivators from Taobao that plug into the OBD port, disabling the feature in just a few simple steps. However, this method isn't reliable—once the vehicle undergoes an update, the device might stop working or cause conflicts. Moreover, modifying the ECU code carries significant risks, increases power consumption, and could lead to premature battery failure, costing around a thousand yuan to replace. From an environmental perspective, the auto start-stop was designed to reduce emissions, so forcibly disabling it might be illegal. Personally, I don't think it's worth the trouble. Instead of going through all that, it's better to turn off the auto mode in the settings and manually control the air volume and lights each time. During maintenance, ask the technician to check if the sensors are dirty, which might be causing false triggers—this approach is both worry-free and safe. Driving should be comfortable, but avoiding unnecessary system modifications is the right way to go.

Want to permanently disable the CR-V's auto start-stop? I know some DIY methods: using an OBD tool to modify settings or disconnecting the battery sensor wire. But these operations are complex, and mistakes could fry the circuit board. Manufacturers don't recommend altering the factory design since auto start-stop protects the environment and saves fuel. Once modified, the warranty is void, and dealership repairs are expensive and troublesome. Rather than taking risks, it's simpler and more reliable to press the center console button to disable auto start-stop after ignition. If the battery ages quickly, replace it promptly to prevent minor issues from becoming major hazards.

As a car owner, I don't think permanently disabling the start-stop system is a good idea. The Crown Road system is computer-controlled, and while it can be forcibly modified using OBD devices or software flashing, it's costly and violates regulations. After modification, there's no improvement in fuel efficiency, and it actually increases battery load, making it prone to failure. In daily driving, pressing the off button each time you start the car isn't much effort—just make it a habit. Pay attention to battery health: weak batteries in older cars can cause the start-stop system to activate too frequently. Regularly checking voltage or replacing the battery can alleviate this issue. Prioritize safe driving; don't add risks just to save a little trouble.

The CR-V's start-stop system cannot be completely turned off, and some people have tried using OBD plugins or ECU flashing to permanently disable it. However, this interferes with the computer's data interpretation and may trigger fault codes, causing warning lights to illuminate. Battery life is also affected because the start-stop system requires stable power supply, and modifications add extra load, leading to more frequent battery replacements and unnecessary expenses. Legally, many regions prohibit modifying the system, and getting caught may result in fines. Personally, I recommend the temporary disable method: press the start-stop button once after ignition to disable it for the entire trip. Pay attention to battery maintenance—replacing it when worn out can reduce start frequency. In noisy driving environments, manually controlling the button is much more reliable than hardware modifications and also protects the vehicle's electronic components.
