Solution

1. Preparation

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

2. Check and Replace ABS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller or pliers to remove the ABS fuse.
Inspect the fuse for any signs of damage. If blown, replace it with a fuse of the same amperage.

3. Inspect and Clean Wheel Speed Sensors

Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor wiring harness.
Clean the sensor and the sensor mounting area with brake cleaner to remove any debris.
Reconnect the sensor and secure it in place.

4. Brake Fluid Check and Replacement

Remove the brake fluid reservoir cap.
Check the fluid level; if low, top it up with the recommended brake fluid type (DOT 3 or DOT 4).
If the fluid appears contaminated, perform a brake fluid flush by draining and replacing the fluid in the system.

5. Test and Replace Faulty Components

Use a multimeter to test the wheel speed sensors for resistance (typically 1,000 to 2,000 ohms). Replace any sensors that are out of specification.
If issues persist, inspect the ABS control module and wiring for faults, replacing any damaged components.
