Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel assembly.
Remove any debris or dirt from the sensors and connectors.
Check the wiring for any signs of wear or damage.
If necessary, replace any faulty sensors.

3. Check the ABS Module

Locate the ABS module in the engine compartment.
Inspect the connectors for corrosion or loose connections.
If error codes indicate a fault with the ABS module, consider replacing it.
Reconnect any loose wires and ensure a secure fit.

4. Test the Traction Control Switch

Locate the traction control switch on the dashboard.
Remove the switch and use a multimeter to check for continuity.
Replace the switch if it fails the continuity test.

5. Verify Tire Condition and Pressure

Inspect all tires for proper tread depth and signs of uneven wear.
Use a tire pressure gauge to check each tire’s pressure, adjusting to the manufacturer's specifications as needed.
Replace tires if they are worn beyond safe limits.
