Why does Honda keep showing the power-on status?
3 Answers
Because some Honda models require shifting to P gear to turn off the engine. Here is some information about Honda: 1. Introduction: Honda Motor Co., Ltd., formerly known as Honda Technology Research Institute, was established in September 1948 by the legendary founder Soichiro Honda. 2. Logo: In the 1980s, Honda established a trademark design research group and selected the current three-string speaker-style logo, which is the framed 'H', from over 2,500 design drafts from around the world.
I also experienced the dashboard constantly displaying the 'power on' warning when driving my Honda, which was quite annoying. This is usually caused by a malfunction in the key sensing system, possibly due to a dead key fob battery or the vehicle's anti-theft system failing to detect the correct signal. Electrical shorts can also trigger this issue, such as when sensors for the trunk or hood get stuck in the 'open' position, causing the computer to misread the status. My suggestion is to first manually check if all doors and the hood are properly closed, then try disconnecting the negative battery terminal for a few minutes before reconnecting it—sometimes this can reset the system. If the problem persists, it might be due to aged relays or blown fuses, in which case you'll need a professional scan tool at a repair shop to read the error codes. This issue isn't uncommon in Honda models, and addressing it promptly prevents future hassles like being unable to lock the car or a drained battery. Calling for roadside assistance would be a much bigger headache—safety always comes first.
In my experience handling similar issues, I often find that Honda vehicles displaying a power-on state originate from complex electrical architectures. For instance, worn ignition switch contacts can send false signals, or a faulty body control module may fail to properly shut down the power circuit. Honda's design sometimes causes relays to stick, continuously activating the power indicator, especially when terminals corrode in humid environments. During inspections, prioritize checking the fuse box—if there are signs of blown fuses, replace them first, as this typically indicates excessive short-circuit current. I've also encountered cases where conflicts arose from aftermarket GPS installations, interfering with the computer's judgment. A straightforward solution is to disconnect auxiliary electrical devices and then use a multimeter to check if the main circuit voltage remains stable above 12V, avoiding voltage fluctuations that trigger false readings. If this doesn’t work, I recommend seeking a professional technician for a comprehensive diagnosis—DIY attempts carry significant safety risks.
