Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Tools Required: OBD-II scanner, socket set, multimeter, cleaning supplies, torque wrench.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel.
Remove the sensor mounting bolts using a socket set.
Carefully pull the sensor out and inspect for dirt or damage.
Clean the sensor with brake cleaner and a soft cloth.
Reinstall the sensor and tighten the bolts to manufacturer specifications (usually around 7-10 ft-lbs).

3. Check ABS Module and Wiring

Locate the ABS module under the hood near the master cylinder.
Visually inspect the wiring harness and connectors for any signs of wear or damage.
Use a multimeter to check for continuity in the wiring.
If damaged, repair or replace the wiring as necessary.

4. Verify Brake Fluid Level and Condition

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the "MIN" and "MAX" lines.
If the fluid is low, top it off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
If the fluid is dark or contaminated, flush the brake system and replace with new fluid.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Remove the switch panel using a trim removal tool.
Check for any loose connections or damage to the switch.
Test the switch functionality with a multimeter; replace if faulty.
