Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Addressing Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document all error codes.
Clear codes and retest to see if they return, indicating persistent issues.

3. Inspecting the Battery and Charging System

Use a multimeter to check the battery voltage (should be around 12.6 volts when fully charged).
Check the alternator output (should be between 13.8 to 14.4 volts when the engine is running).
Inspect battery terminals for corrosion and ensure they are tight.

4. Fluid Inspection and Replacement

Check engine oil level using the dipstick; replenish if low with the manufacturer-recommended oil.
Inspect brake fluid level; add fluid if necessary and check for leaks in brake lines or master cylinder.

5. ABS and Traction Control Sensor Inspection

Locate ABS sensors on each wheel; clean with brake cleaner and check for physical damage.
Ensure all wiring connected to the sensors is secure and undamaged.

6. Brake System Functionality Check

Inspect brake pads and rotors for wear; replace if necessary.
Test the brake pedal feel and ensure there are no leaks in the brake system.
