What is the solution for Volkswagen electronic parking brake malfunction?
1 Answers
If the electronic parking system malfunctions, it is likely due to an issue with the electronic handbrake, worn brake pads, an electronic system problem, or a battery power supply issue. This must be addressed at a repair shop using a diagnostic scanner to read the fault codes, followed by repairs based on the fault codes. More relevant information is as follows: 1. Function of electronic parking: The electronic parking system is used for temporary parking in stop-and-go traffic. For example, when stopping at a red light, after releasing the brake pedal, the auto-hold function quietly activates, locking the wheels until the accelerator pedal is pressed again, at which point the electronic parking automatically unlocks the wheels. This action is much faster than pressing the electronic handbrake. 2. ESP module: Besides convenience, electronic parking also prevents rollback. Since the electronic parking function is developed from the ESP module, during parking, the ECU uses sensors installed in the vehicle to determine the vehicle's levelness and the torque required for wheel braking, deciding whether to apply braking to prevent rollback. Moreover, the braking force applied by the electronic parking to the wheels is not excessive, just enough to prevent wheel movement, ensuring the vehicle does not lurch forward when the accelerator is pressed again.
