Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to ensure safety.

2. Check Wheel Speed Sensors

Tools Required: Multimeter, socket set
Remove the wheel and tire assembly to access the wheel speed sensor.
Disconnect the sensor's electrical connector.
Using a multimeter, check the sensor's resistance; it should be within manufacturer specifications.
If out of range, replace the wheel speed sensor.

3. Inspect ABS Control Module

Tools Required: OBD-II scanner
Reconnect the battery and use an OBD-II scanner to read any fault codes from the ABS control module.
If codes indicate a failure, consider replacing the ABS control module or performing a software update.

4. Brake Fluid Inspection

Tools Required: Brake fluid tester
Check the brake fluid reservoir; if low, top off with the manufacturer-recommended brake fluid.
If the fluid is contaminated, flush the brake system and refill with new fluid.

5. Wiring Inspection

Inspect the wiring harness for any visible damage or corrosion.
Clean any corroded connectors with electrical contact cleaner.
Repair or replace any damaged wiring as necessary.
