Is it normal for the Corolla SOS green light to stay on?

The Corolla SOS green light staying on is normal. It indicates that the vehicle's emergency call function is in an online state. Activating self-check function: After parking and turning off the engine for 5-10 minutes, without pressing the brake pedal, press the start button once, or without depressing the clutch, turn the key halfway to the 'on' position. The vehicle will initiate self-check function after powering on. Wait for 5-10 seconds and observe whether the warning lights on the dashboard turn off, leaving only the engine warning light. 4S shop or repair shop inspection: If other warning lights remain on, it's necessary to have the corresponding modules and components inspected at a 4S shop or repair shop. If only the engine warning light stays on, restart the engine and observe whether the engine warning light remains illuminated. If the engine warning light turns off, there's no issue. If the engine warning light continues to stay on, it's necessary to have the engine-related components and modules inspected at a 4S shop or repair shop.
I've been driving a Corolla for several years, and I must say it's a bit odd that the SOS green light stays on constantly. Generally, the SOS system is the vehicle's built-in emergency call function, and the green light should indicate that the system is on standby or connected properly. However, if it stays lit without blinking, it might indicate a system issue. For instance, my car once had a similar problem, and after checking at the 4S shop, it turned out to be poor contact in the control module or unstable battery power, affecting overall performance. This reminds us to pay attention to regular checks while driving, especially before long trips. It's best to refer to the user manual or the car's connected app to confirm if the system is activated or malfunctioning. In short, don't take it lightly—the SOS function could be a lifesaver in emergencies. I recommend taking the time to visit a professional repair shop for an inspection to prevent minor issues from turning into major problems.
As an automotive technology enthusiast, I believe the constant illumination of the Corolla's SOS green light warrants attention to its operational logic. The SOS system typically connects to a service center via the vehicle's network, with the green light indicating normal communication. However, if it remains lit without turning off, it may suggest a software bug or hardware failure, such as a sensor malfunction. While tinkering with the vehicle's systems, I've found that restarting the car's power can sometimes resolve temporary issues—try turning the ignition on and then off. Given its safety implications, such systems are designed for sensitive responses, and unintended constant illumination could drain the battery or trigger false alarms, affecting driving comfort. For maintenance, it's advisable to check the fuses and antenna connections. After all, with technology evolving rapidly, understanding its mechanisms helps us use our cars more smartly, ensuring peace of mind with every start.
