Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery to prevent electrical shorts during repair.

2. Addressing Error Codes

Clear the error codes using the OBD-II scanner after noting them down.
If the codes reappear, proceed to inspect the corresponding components based on the codes retrieved.

3. Brake Component Replacement (if necessary)

Brake Pads Replacement:
- Lift the vehicle using a jack and secure it on jack stands.
- Remove the wheel to access the brake assembly.
- Unbolt the caliper using a socket wrench and carefully slide it off the rotor.
- Remove the old brake pads and install new ones, ensuring proper orientation.
- Reattach the caliper and wheel, then lower the vehicle.
Brake Fluid Change:
- Locate the brake fluid reservoir and remove the cap.
- Use a turkey baster to remove old fluid and replace it with new DOT fluid.
- Bleed the brakes to remove air from the system:
  1. Start at the furthest brake from the master cylinder (usually right rear).
  2. Open the bleeder valve while having an assistant press the brake pedal.
  3. Close the valve before the pedal is released, and repeat until fluid runs clear.
  4. Move to the next brake and repeat the process until all are bled.

4. Final Checks

Reconnect the battery.
Clear any remaining error codes and perform a visual inspection of all replaced components.
