Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Remove the sensor from its mount using a socket set.
3. Clean the sensor and connector with electrical contact cleaner.
4. Reinstall the sensor, ensuring it is secured properly.

3. Check Brake Fluid Level

Sub-steps:
1. Locate the brake fluid reservoir (usually near the driver's side).
2. Check the fluid level against the minimum and maximum marks.
3. If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
4. Check for any leaks in the brake lines or around the master cylinder.

4. Test ABS Module

Sub-steps:
1. Reconnect the battery terminal.
2. Use the OBD-II scanner to check for ABS module errors.
3. If there are codes, follow the manufacturer's procedure for testing the ABS module functionality.
4. If defective, replace the ABS module according to manufacturer specifications.

5. Verify Traction Control Switch

Sub-steps:
1. Locate the traction control switch on the dashboard.
2. Remove the switch panel using a trim removal tool.
3. Inspect the switch for damage or wear.
4. If necessary, replace the switch with a new one.
