Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on electronic components.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter
Locate the wheel speed sensors at each wheel hub.
Remove the bolts securing the wheel speed sensor using the socket set.
Disconnect the electrical connector from the sensor.
Inspect the sensor for damage. If defective, replace it with a new sensor.
Reinstall the new sensor and reconnect the electrical connector.

3. Check and Replace ABS Control Module

Tools Required: Torque wrench, diagnostic scanner
Locate the ABS control module, typically near the brake master cylinder.
Check the module for error codes using the diagnostic scanner.
If codes indicate a failure, remove the module by unscrewing the securing bolts with the torque wrench.
Disconnect the wiring harness and replace it with a new ABS module.
Reconnect the battery and clear any error codes using the scanner.

4. Brake Fluid Level Check

Tools Required: Brake fluid funnel
Open the hood and locate the brake fluid reservoir.
Check the fluid level – it should be between the "MIN" and "MAX" marks.
If low, fill with the recommended brake fluid type (usually DOT 3 or DOT 4).
Securely close the reservoir cap.
