Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts during repairs.
Ensure the vehicle is on a flat surface and safely secured with wheel chocks.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning solution, soft cloth.
Steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Disconnect the sensor's electrical connector.
4. Remove the wheel speed sensor from its mount using a socket.
5. Clean the sensor and its mounting area with a suitable cleaning solution and a soft cloth.
6. Reinstall the sensor, reconnect the electrical connector, and replace the wheel.

3. Check ABS System

Tools Required: OBD-II scanner.
Steps:
1. Use the OBD-II scanner to check for ABS-related fault codes.
2. If any codes are present, follow the manufacturer's guidelines for specific repairs.
3. Clear the fault codes and perform a test drive to see if the traction control light reappears.

4. Inspect the Traction Control Switch

Tools Required: Multimeter.
Steps:
1. Locate the traction control switch on the dashboard.
2. Use a multimeter to check for continuity when the switch is pressed.
3. If the switch is faulty, replace it with a new one.

5. Check Brake Fluid Level

Steps:
1. Locate the brake fluid reservoir under the hood.
2. Check the fluid level; it should be within the recommended range.
3. If low, refill with the manufacturer-recommended brake fluid type.

6. Battery Voltage Test

Tools Required: Multimeter.
Steps:
1. Reconnect the battery and use a multimeter to check the voltage.
2. Ensure the voltage is between 12.4V to 12.6V with the engine off.
3. If the voltage is low, charge or replace the battery as necessary.
