Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and safely supported.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel and tire to gain access to the wheel speed sensors.
Check the sensor wiring for any damage or corrosion.
Use a multimeter to test the sensor resistance; replace if outside manufacturer specifications.

3. Check ABS Control Module

Tools Required: OBD-II scanner
Reconnect the battery and turn on the ignition.
Use the OBD-II scanner to check for any fault codes related to the ABS control module.
Repair or replace the ABS control module if necessary, following manufacturer specifications for installation.

4. Examine Brake System

Tools Required: Brake fluid tester
Check the brake fluid level in the master cylinder; top off if low.
Inspect brake pads and rotors for wear and replace if necessary.
Clear any air in the brake lines if brake fluid was added.

5. Test Traction Control Switch

Tools Required: Multimeter
Locate the traction control switch and remove it from the dashboard.
Use a multimeter to test the switch for continuity; replace if it fails the test.
