Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, jack and jack stands, torque wrench.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the wheel speed sensors at each wheel hub.
3. Visually inspect each sensor for dirt, damage, or corrosion.
4. Remove the sensor connector and use a multimeter to check for continuity.
5. If damaged, replace the faulty wheel speed sensor.

3. Check Brake Fluid and System

Sub-steps:
1. Inspect the brake fluid reservoir to ensure it is at the recommended level.
2. Look for leaks in brake lines and connections.
3. If the fluid is low, fill it with the appropriate brake fluid type as specified in the owner's manual.
4. If leaks are found, replace the damaged lines or components.

4. Test ABS Module

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to check for any ABS-related codes.
3. If codes are present, refer to the service manual for the specific diagnostic procedure for the ABS module.
4. If necessary, replace the ABS module according to manufacturer specifications.

5. Inspect Traction Control Switch

Sub-steps:
1. Locate the traction control switch, usually on the dashboard.
2. Remove the switch from the dashboard assembly.
3. Use a multimeter to check for continuity when the switch is activated.
4. Replace the switch if it fails the continuity test.
