How to Solve the Issue of Continuously Flashing Electronic Handbrake?
2 Answers
Poor contact in the handbrake switch causes the flashing. You can remove the handbrake cover, locate the handbrake switch, and first inspect the switch; Poor contact in the handbrake light power wire or a broken wire harness can also cause this. Use a multimeter to check the voltage of the red wire; Poor contact in the handbrake indicator light on the dashboard can lead to flashing. You can unplug the electrical connector of the handbrake switch.
I've encountered the situation where the electronic parking brake light flashes, which is quite common. It's usually caused by sensor failure or system errors. At that time, the light kept flashing while my car was moving. I tried turning off and restarting the engine, and sometimes the issue was resolved after the system reset. But if the light remains on, it might be due to insufficient battery power causing voltage instability. It's recommended to first check the battery status with a voltmeter. Or inspect the relevant fuses in the fuse box to see if they're blown. Most of the time, these minor issues can be fixed by yourself, but for safety's sake, don't ignore them. The electronic parking brake relies on circuit signals and is easily affected by environmental factors, such as humid weather or aging wires. That time, after repeated restarts didn't work, I went to a repair shop, and they diagnosed it as a loose sensor connector—cleaning it fixed the problem. So now I regularly check the battery and sensor wiring to prevent such minor issues. If you encounter this while driving, don't panic; pull over to handle it. Regular maintenance can indeed save you trouble.
