Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the vehicle's battery to ensure safety during repairs.

2. Brake Fluid Inspection

Remove the master cylinder reservoir cap.
Inspect the fluid level; if low, top off with the recommended brake fluid type (DOT 3, DOT 4, or as specified in the owner's manual).
If the fluid appears dirty or contaminated, proceed to flush the brake system.

3. Brake Pad and Rotor Inspection

Remove the wheel to access the brake assembly.
Check the brake pads for thickness; replace if below the manufacturer's minimum specification.
Inspect the rotors for scoring or warping; replace if necessary.
Reinstall the wheel after repairs and torque to the manufacturer’s specifications.

4. ABS Sensor Inspection

Locate the ABS sensors on each wheel hub.
Disconnect the sensor connectors and visually inspect for damage or corrosion.
Use a multimeter to test the sensor resistance; replace if outside the specified range.
Reconnect the sensors ensuring a secure connection.

5. ABS Module Test

Reconnect the battery and turn on the vehicle.
Use the OBD-II scanner to clear any existing codes.
Perform a test drive to monitor the ABS functionality.
Re-scan for error codes to ensure the issue is resolved.
