Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to ensure safety while working on the electrical components.

2. Inspect and Replace Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Tools Required: Socket set, torque wrench, multimeter.
Remove the sensor connector and inspect for corrosion or damage.
If damaged, remove the sensor by unscrewing it from the hub and replace it with a new one.
Reconnect the sensor and secure using the appropriate torque specifications.

3. Check and Replace TCS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Tools Required: Fuse puller or needle-nose pliers.
Identify the TCS fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity (replace if blown).
Insert the new fuse securely into the fuse slot.

4. Inspect ABS Control Module Wiring

Locate the ABS control module, typically near the brake master cylinder.
Look for any frayed wires or loose connections.
Tools Required: Basic hand tools.
Repair any damaged wiring by soldering or using appropriate connectors.
Ensure all connections are tight and secure.

5. Reconnect Battery and Test

Reconnect the vehicle battery terminals securely.
Start the vehicle and check if the traction control warning light is still illuminated.
