Here are the reasons why the steering wheel buttons cannot control the central control screen: 1. The buttons are stuck. Press each button one by one to check if they have elasticity; 2. The keyboard is damp or leaking electricity (clean and dry the circuit board); 3. The protective components and anti-interference capacitors of the keyboard's vertical and horizontal lines are leaking or short-circuited (determined by measuring the resistance to ground or the voltage of the keyboard contacts); 4. The flip control circuit has failed; 5. The CPU is poorly soldered or damaged (re-solder or replace); 6. The circuit board is broken. Additional information: If the buttons on the car steering wheel malfunction, you can troubleshoot from a functional perspective: Functional faults generally include multimedia volume adjustment, Bluetooth phone calls, multimedia track skipping, etc. If these functions malfunction or behave abnormally, you can manually operate the multimedia buttons on the central console or the corresponding function buttons/knobs on the touchscreen.

As an experienced driver, I've encountered steering wheel button failures several times, mostly due to physical contact issues. Dust or grease buildup on button surfaces can prevent conductivity when pressed, blocking signals from reaching the infotainment screen. Alternatively, aging internal springs may lose elasticity, rendering buttons unresponsive. I recommend thoroughly cleaning button crevices first, using a soft cloth dampened with alcohol. If that doesn't work, check for loose or broken wiring behind the steering wheel - some vehicles suffer interface corrosion from car wash water seepage. When experiencing delayed or unresponsive buttons while driving, avoid forceful pressing to prevent distraction. Instead, find a safe spot to park and perform basic troubleshooting, or visit a repair shop for comprehensive inspection to prevent minor issues from escalating into major repairs.

How long do I need to wait if I schedule Subject 3 before Subject 2?

After passing the Subject 2 test, you must wait at least 10 days before scheduling the Subject 3 test, with the usual interval being 15 to 20 days. Difficulties in Subject 3: 1. Speed and gear mismatch. The Subject 3 test has a mileage requirement, and gear shifting is one of the mandatory test items. However, during actual driving, students often encounter issues of high gear at low speed or low gear at high speed. If this occurs during the test, it will result in failure. Matching speed with the appropriate gear is a challenge for many students. 2. Deviation in straight-line driving. During the Subject 2 test, instructors also teach students how to drive straight. However, in the Subject 3 test, because it involves driving on actual roads over a longer distance, many students unknowingly deviate from the straight path without correcting, leading to test failure.
