Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, wheel chocks, jack, jack stands.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Sub-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. Inspect the sensor for dirt, damage, or loose connections.
4. Clean the sensor with electrical cleaner if dirty.
5. Reconnect the sensor and wheel, then lower the vehicle.

3. Check Brake Fluid Level

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Inspect the fluid level; it should be at the "Full" mark.
3. If low, top off with the manufacturer-recommended brake fluid.
4. Reconnect the battery.

4. Inspect ABS Module and Wiring

Sub-steps:
1. Locate the ABS module, usually mounted near the brake master cylinder.
2. Check for any visible signs of damage or corrosion on the module and wiring harness.
3. Use a multimeter to test the voltage and continuity of the wires leading to the module.
4. Repair any damaged wiring or connectors.

5. Clear Error Codes

Sub-steps:
1. Reconnect the battery.
2. Use the OBD-II scanner to clear any error codes.
3. Start the engine and observe if the traction control light remains illuminated.
