Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery before beginning any electrical work to ensure safety.

2. Address Fault Codes

Connect an OBD-II scanner and retrieve fault codes.
If codes are present, address the specific issues indicated (e.g., wheel speed sensor failure).

3. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter
Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector from the sensor.
Remove the mounting bolt using a socket and ratchet.
Pull the sensor out of the hub and inspect for damage.
If faulty, install a new sensor by reversing the removal steps, ensuring it is properly seated and torqued to manufacturer specifications.

4. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Locate the brake fluid reservoir under the hood.
Check the fluid level; if low, refill with the appropriate brake fluid as specified in the owner’s manual.
Inspect for any leaks in the brake system.

5. Inspect ABS Control Module and Wiring

Tools Required: Multimeter
Locate the ABS control module, usually found near the master cylinder.
Inspect the wiring harness for any signs of fraying or disconnection.
Use a multimeter to test for continuity in the wiring.
Repair or replace any damaged wiring as necessary.

6. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Test the switch operation by pressing it and observing any changes in dashboard indicators.
Replace the switch if it is non-functional.
