Solution

1. Preparation

Gather necessary tools and safety gear.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Scan for Error Codes

Connect an OBD-II scanner to the vehicle's diagnostic port.
Record any stored error codes related to ABS or traction control.

3. Inspect ABS Sensors

Raise the vehicle securely using jack stands.
Remove the wheel to access the ABS sensor.
Visually inspect the sensor and its wiring for damage, dirt, or disconnection.
Clean the sensor and its mounting area if dirt is present.

4. Check Brake Fluid Level

Open the hood and locate the master cylinder reservoir.
Ensure the brake fluid is at the appropriate level; if low, top off with manufacturer-recommended fluid.
Inspect for any leaks around brake lines and hoses.

5. Test Wheel Speed Sensors

Disconnect the wiring harness from the wheel speed sensor.
Use a multimeter to measure the resistance of the sensor; compare with manufacturer specifications.
Replace any faulty sensors.

6. Reconnect and Clear Codes

Reconnect any disconnected components or wiring.
Clear the error codes using the OBD-II scanner.
Test drive the vehicle to verify the ABS and traction control systems are functioning properly.
