Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure you have a clear workspace and necessary safety equipment (gloves, goggles).
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Address Error Codes

Sub-steps:
1. Reconnect the OBD-II scanner and clear any fault codes.
2. Perform a test drive to check if the error codes reappear.
3. If codes return, refer to the specific code definitions to identify the affected component.

3. Brake Fluid Check

Sub-steps:
1. Locate the brake fluid reservoir.
2. If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
3. Inspect for leaks and address any fluid loss.

4. Brake Component Inspection

Sub-steps:
1. Remove the wheel to access brake components.
2. Examine brake pads for thickness; replace if under 3mm.
3. Check rotors for scoring or warping; replace if necessary.
4. Ensure calipers are functioning correctly; replace or rebuild if sticking.

5. Brake Switch Functionality

Sub-steps:
1. Locate the brake light switch mounted on the brake pedal assembly.
2. Use a multimeter to test for continuity when the pedal is pressed.
3. Replace the switch if it does not function correctly.

6. ABS Sensor Testing

Sub-steps:
1. Locate the ABS wheel speed sensors at each wheel hub.
2. Inspect wiring and connections for damage or corrosion.
3. Test sensor output with a multimeter; replace if out of specification.
