What is the reason why the 3008 parking brake failure cannot start?
2 Answers
3008 parking brake failure cannot start because there is a fault in the parking brake system. It may be caused by a problem with the brake light switch, resulting in the ECU not receiving the normal start power signal. It is recommended to contact a professional technician at a 4S shop to use a computer to check the specific fault content and then carry out targeted repairs. The following are methods to reduce car failures: 1. Engine oil change knowledge: The engine oil change cycle is 5,000 kilometers. Not all models are suitable for car owners to change the oil themselves. You can learn to check the oil dipstick to determine whether the oil needs to be changed. When changing the oil, the oil filter must also be replaced. 2. Antifreeze usage knowledge: Antifreeze is best used all year round. In addition to its antifreeze and cooling functions, antifreeze also has cleaning, rust removal, and anti-corrosion effects, reducing corrosion of the radiator and protecting the engine. Pay attention to choosing the correct color of antifreeze and do not mix different types. 3. Brake fluid usage: The function of the brake system is closely related to the brake fluid. When inspecting or replacing brake pads, brake discs, and other hardware, do not forget to check whether the brake fluid needs to be added or replaced. 4. Transmission oil: To ensure flexible steering of the car, frequently check the transmission oil. Whether it is gear oil or automatic transmission fluid, pay attention to the oil model.
Last time my friend's 3008 also encountered this issue, I spent quite some time helping him figure it out. A parking brake system failure can cause the entire vehicle to enter a protective state, with the computer directly locking the ignition program to prevent startup. The most common reason is an aging or depleted battery, since the electronic parking brake requires stable voltage to operate; another possible cause is poor contact in the brake sensor wiring or a control module crash. Also, don’t forget to check the foot brake switch—if the signal isn’t transmitted to the computer when pressing the brake, the anti-theft system will prevent ignition. An emergency solution is to try jump-starting and restarting; if that doesn’t work, call for a tow truck immediately. Corroded battery terminals can also trigger a chain reaction of faults, so they should be disassembled and cleaned thoroughly.
