2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel and tire.
Locate the wheel speed sensor on each wheel hub.
Disconnect the sensor connector and check the resistance using a multimeter; compare readings to manufacturer specifications.
Clean the sensor and its mounting area; replace if faulty.

3. Check Brake Fluid Level

Tools Required: None
Locate the brake fluid reservoir under the hood.
Ensure the brake fluid is at the proper level; refill with manufacturer-recommended fluid if low.
Inspect for any leaks in the brake lines or around the reservoir.

4. Inspect ABS Module

Tools Required: Socket set, screwdriver
Locate the ABS module, usually near the master cylinder.
Check for any visible damage, corrosion, or connection issues at the module.
If necessary, remove the module and inspect the connectors and wiring.
