Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Instructions:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Inspect the sensor and wiring for any visible damage or disconnections.
4. Using a multimeter, check for continuity in the sensor. If no continuity is found, replace the sensor.
5. Reinstall the wheel and lower the vehicle.

3. Check Traction Control Module

Tools Required: Diagnostic scanner
Instructions:
1. Reconnect the battery terminal.
2. Use the diagnostic scanner to check for DTCs related to the traction control module.
3. If codes indicate a faulty module, proceed with replacement.
4. If no faults are found, check the connections and wiring to the module for corrosion or damage.

4. Inspect Brake Fluid Level

Tools Required: Brake fluid tester (optional)
Instructions:
1. Locate the brake fluid reservoir.
2. Check the fluid level; if low, fill with the manufacturer-recommended brake fluid type.
3. Inspect for leaks in the brake lines or around the calipers.

5. Test ABS Functionality

Tools Required: Diagnostic scanner
Instructions:
1. With the vehicle running, activate the ABS system using the diagnostic scanner.
2. Ensure that all ABS components operate correctly without triggering any fault codes.
