Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Diagnose and Fix Wheel Speed Sensors

Sub-steps:
- Locate the wheel speed sensors at each wheel hub.
- Clean the sensors and their mounting areas with brake cleaner.
- Check the wiring harness for any signs of wear or disconnection.
- If damaged, replace the wheel speed sensors with OEM parts.

3. Inspect and Repair ABS Control Module

Sub-steps:
- Locate the ABS control module, typically found near the master cylinder.
- Disconnect the connector and inspect for corrosion or damage.
- Clean the connector and terminals with electrical contact cleaner.
- Reconnect and ensure a secure fit. If issues persist, consider replacing the module.

4. Check Brake Fluid and ABS Pump

Sub-steps:
- Inspect the brake fluid reservoir; top off with the recommended brake fluid if low.
- Check for contamination; if the fluid appears dark or contains particles, perform a brake fluid flush.
- Inspect the ABS pump for any signs of leaks; replace if necessary.

5. Reconnect and Test

Sub-steps:
- Reconnect the battery.
- Start the vehicle and check if the ABS light is still illuminated.
- Perform a test drive to verify ABS functionality.
