What is the reason for the yellow light on the Envision's electronic parking brake?

This indicates that there is a fault with the electronic parking brake, and it needs to be repaired at a 4S shop. Below is relevant information about the brake: 1. Working principle: The brake provides resistance to the car when parking. The handbrake in manual cars or the parking gear in automatic cars serves as the brake. The car uses an electronic parking brake system, which combines temporary braking during driving with long-term braking after parking, controlled electronically. The working principle of the parking brake, similar to the mechanical handbrake, achieves the parking effect through friction between the brake pads and the brake disc. 2. Types of brakes: Generally, car brakes can be divided into drum brakes and disc brakes. Small cars usually use drum brakes, also known as drum brake systems.
Last month, while I was driving my Enclave on the road, the yellow light of the electronic parking brake suddenly came on, which really freaked me out. I asked a friend at the repair shop, and he explained that it could be a sensor malfunction, low battery voltage, or a problem with the control module. I tried restarting the infotainment system and the parking system myself first—sometimes that resets it, but it didn’t work that time. Later, after checking, I found the battery was drained. After charging it, the light went off, but it’s hard to say whether it was caused by a short circuit in the wiring. If you encounter a similar situation, don’t rush to drive—check the battery level or fuses first. If that doesn’t help, it’s safer to get a professional diagnosis as soon as possible.
