Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Replace ABS Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Remove the wheel to access the brake components.
3. Locate the ABS wheel speed sensor; disconnect the wiring harness.
4. Unscrew the sensor using a socket set and remove it from the hub.
5. Install the new ABS sensor in reverse order, ensuring it is seated properly.
6. Reconnect the wiring harness and reinstall the wheel.

3. Check and Refill Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Inspect the fluid level; if low, clean the area around the reservoir cap.
3. Remove the cap and fill the reservoir with the recommended brake fluid type (usually DOT 3 or DOT 4).
4. Reinstall the cap securely.

4. Clear Error Codes

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to clear any logged ABS error codes.
3. Turn the ignition to the "ON" position without starting the engine and check if the ABS light is off.
