Solution

1. Preparation

Gather tools such as an OBD-II scanner, multimeter, socket set, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Update Software

Connect the OBD-II scanner to the vehicle's diagnostic port.
Follow on-screen prompts to check for software updates.
If available, download and install the latest software version.

3. Inspect Battery Health

Use a multimeter to measure the battery voltage while the vehicle is off and during idle.
If voltage is below 12.4 volts while off or fluctuates significantly during idle, consider replacing the battery.

4. Clean Throttle Body

Remove the air intake duct leading to the throttle body using the socket set.
Carefully detach the throttle body from the intake manifold.
Use throttle body cleaner and a soft brush to remove carbon buildup.
Reassemble all components, ensuring proper torque specifications (usually around 15-20 Nm).

5. Check Brake System

Inspect the brake booster and master cylinder for leaks or malfunctions.
Ensure brake lights are functioning correctly, as this can affect power management.
Replace any faulty components as necessary.
