Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, cleaning brush, brake fluid.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Step 1: Locate the wheel speed sensors on each wheel hub.
Step 2: Remove the screws or bolts securing the sensors using a socket set.
Step 3: Clean the sensor area with a brush to remove any dirt or debris.
Step 4: Reinstall the sensors and secure them properly.

3. Check ABS Module and Wiring

Step 1: Locate the ABS module, typically found near the brake master cylinder.
Step 2: Inspect the wiring harness for any visible damage or corrosion.
Step 3: Use a multimeter to check for continuity in the wiring between the ABS module and the wheel speed sensors.
Step 4: Repair or replace any damaged wiring as needed.

4. Test Traction Control Switch

Step 1: Locate the traction control switch on the dashboard.
Step 2: Remove the switch from the dashboard.
Step 3: Use a multimeter to test the switch for proper function (check for continuity when pressed).
Step 4: Replace the switch if it fails the test.

5. Check Brake Fluid and System

Step 1: Open the hood and locate the brake fluid reservoir.
Step 2: Check the brake fluid level and top off if necessary.
Step 3: Inspect brake lines for leaks and ensure they are securely connected.
Step 4: If leaks are found, replace the affected brake lines or components.
