Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure it is in park mode.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean the sensors with a suitable cleaner to remove any debris.
Check the wiring harness connected to each sensor for fraying or disconnection.
Use a multimeter to test the resistance of each sensor; it should typically be between 1,000 to 1,500 ohms.

3. Check Brake Fluid and System

Inspect the brake fluid reservoir for proper fluid level.
If low, refill with OEM brake fluid.
Check for any leaks in the brake lines or calipers.

4. Examine ABS Module and Wiring

Remove any covers blocking access to the ABS module.
Visually inspect the ABS module for corrosion or damage.
Use a multimeter to check the voltage at the ABS module connector.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Remove the switch and test for continuity using a multimeter.
Replace the switch if found faulty.

6. Verify Tire Condition

Inspect all tires for uneven wear or damage.
Ensure all tires are inflated to the recommended pressure.
Replace any damaged tires with OEM or equivalent.
