Solution

1. Preparation

Gather required tools and parts.
Disconnect the vehicle's battery to prevent electrical shorts.
Ensure the vehicle is on a flat surface and securely elevated if necessary.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Sub-steps:
1. Remove the wheel covers or tires to access the wheel speed sensors.
2. Disconnect the wiring harness from each wheel speed sensor.
3. Use a multimeter to check resistance across the sensor terminals. Compare readings to manufacturer specifications.
4. Clean the sensors and surrounding area to remove debris.

3. Check Brake System Components

Tools Required: Brake cleaner, torque wrench
Sub-steps:
1. Inspect the brake lines and ABS module for any visible damage or leaks.
2. Ensure all electrical connections to the ABS module are secure.
3. If necessary, replace any damaged components using a torque wrench to tighten to manufacturer specifications.

4. Test Traction Control Switch

Tools Required: Multimeter
Sub-steps:
1. Locate the traction control switch on the dashboard.
2. Use a multimeter to test for continuity when the switch is pressed.
3. Replace the switch if it does not show continuity.

5. Reconnect Battery and Clear Codes

Tools Required: None
Sub-steps:
1. Reconnect the vehicle's battery.
2. Use the OBD-II scanner to clear any stored trouble codes.
3. Start the vehicle and check if the traction control disabled light remains off.
