Solution

1. Preparation

Gather tools and park the vehicle on a level surface.
Ensure the engine is off and the keys are removed from the ignition.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Faulty ABS Sensors

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the ABS sensor.
3. Disconnect the wiring harness from the ABS sensor.
4. Remove the sensor bolt with a socket set and extract the sensor.
5. Compare the removed sensor with the new one for compatibility.
6. Install the new ABS sensor and secure it with the bolt.
7. Reconnect the wiring harness and reinstall the wheel.

3. Replace or Repair ABS Module

Sub-steps:
1. Locate the ABS module, typically found near the master cylinder.
2. Disconnect the battery again to ensure safety.
3. Remove the electrical connectors from the ABS module.
4. Unbolt the ABS module from its mounting position using a socket set.
5. Install the new or repaired ABS module in reverse order of removal.
6. Reconnect the battery and clear any fault codes using the OBD-II scanner.

4. Brake Fluid Check and Replacement

Sub-steps:
1. Open the brake fluid reservoir cap.
2. Inspect the fluid; if contaminated or low, siphon old fluid using a turkey baster.
3. Refill with the recommended brake fluid type (usually DOT 3 or DOT 4).
4. Bleed the brake system to remove any air pockets if fluid was replaced.
