Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to ensure safety.

2. ABS Sensor Inspection and Replacement

Inspect ABS Sensors:
- Locate the ABS sensors at each wheel hub.
- Check for dirt, debris, and damage; clean if necessary.
Replace ABS Sensor (if faulty):
- Remove the wheel to gain access to the ABS sensor.
- Unplug the sensor connector.
- Remove the securing bolt and gently pull out the sensor.
- Install the new ABS sensor and secure it with the bolt.
- Reconnect the sensor plug and ensure it is secured properly.

3. Brake Fluid Check and Replacement

Check Brake Fluid:
- Locate the brake fluid reservoir; ensure fluid is at the correct level.
Replace Brake Fluid (if contaminated):
- Remove the reservoir cap and siphon out old fluid.
- Refill with new brake fluid (DOT 3 or DOT 4 as specified by the manufacturer).
- Bleed the brake lines to remove any air.

4. ABS Module Reset

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear any stored ABS error codes.
Check if the ABS light remains off after clearing the codes.
