What is the reason for no display when pressing the auto hold button in Leopaard CS9?

It is very likely that there is a problem with the electronic parking brake, or it could be caused by worn brake pads, an issue with the electronic system, or a problem with the battery power supply. This must be checked at a repair shop using a decoder to read the fault codes, and then repaired according to the fault codes. Below are the solutions for electronic parking brake failures: 1. Reset the electronic parking brake by turning on the car key, pressing the foot brake, then pressing down the electronic parking brake for 5 seconds and pulling it up for another 5 seconds. This will initialize and reset the electronic parking brake. 2. The parking brake, commonly referred to as the handbrake, is usually installed in the driver's right-hand position for easy use. 3. The function of the parking brake is to stabilize the vehicle after it has stopped, preventing accidents caused by rolling on inclined roads. 4. Some automatic transmission models on the market have a foot brake designed on the outside of the driver's left foot with the same function as the handbrake, and some advanced models are also equipped with an electronic parking brake system.
My Leopaard CS9 also experienced the unresponsive auto-hold button issue before. Turned out to be a blown fuse. Located the 10A fuse for the parking system in the fuse box under the lower-left side of the steering wheel and replaced it. Another possibility is poor button contact - the metal contacts inside plastic buttons can oxidize over time. Disassembling and spraying some contact cleaner can serve as a temporary fix. Also remember to check if your brake lights are working, as this function requires the brake pedal to be pressed for activation. If all these appear normal but the issue persists, I'd recommend visiting a professional workshop to inspect wiring or perform system updates. Heard some vehicles may require disconnecting the battery negative terminal to reboot when the system freezes.
