2 Answers
The reasons for the one-button start light flashing continuously are: 1. Installation of a dashcam or other electrical devices causing incorrect wiring; 2. Battery depletion; 3. Key sensing issues, strong nearby magnetic fields may cause interference; 4. Steering wheel being locked. The solutions for the one-button start light flashing continuously are: 1. Rewiring; 2. Replacing the battery; 3. Aligning the key with the one-button start, pressing the one-button start while stepping on the brake, turning the steering wheel, and then pressing the one-button start again. The one-button start device is part of a smart car, serving as a button mechanism to initiate the starting process, and it can also be used to turn off the engine.
I've been driving for decades and have encountered situations where the one-button start light flashes. The most common reason is insufficient or aging car battery power, as the one-button start system requires a stable power supply. If the battery is in poor condition, the light will continuously flash as a warning. Another possibility is an issue with the smart key recognition, such as low key battery power, signal interference, or a strong magnetic field nearby preventing the key from being recognized. Additionally, system software malfunctions can cause this, such as a minor bug in the ECU (Engine Control Unit), requiring a vehicle restart or a visit to the dealership for a software update. Environmental factors like extremely cold or hot weather can also affect the start system's readiness, causing the light to flash continuously. Ignoring this issue may lead to sudden start failure, so it's advisable to first check the battery voltage with a multimeter or visit a professional repair shop for a thorough circuit inspection—don't risk driving with the problem. Regular battery maintenance and checking the one-button start system can prevent this from happening.
