What Causes Automotive Electronic System Failures?

[Riley]

Electronic system failures are most likely caused by issues with the electronic parking brake, worn brake pads, problems within the electronic system itself, or battery power supply issues. It is essential to visit a repair shop to use a diagnostic scanner to read the fault codes and perform repairs based on those codes. More information about electronic systems is as follows: 1. Function of Electronic Systems: The primary function is to provide temporary parking assistance in stop-and-go traffic. When parking, after releasing the brake pedal, the auto-hold feature quietly activates, locking the wheels until the accelerator pedal is pressed again, at which point the electronic parking system automatically unlocks the wheels. This process is much faster than manually engaging the electronic parking brake. 2. Preventing Rollback: During parking, the ECU uses sensors installed in the vehicle to determine the vehicle's level and the required braking torque for the wheels, deciding whether to apply the brakes to prevent rollback. The braking force applied by the electronic parking system to the wheels is not excessive—just enough to prevent movement, ensuring the vehicle does not lurch forward when the accelerator is pressed again.
