Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to avoid any electrical issues during the repair.
Ensure the vehicle is on a flat surface and securely raised using jack stands.

2. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the wheel for better access.
Disconnect the sensor wiring harness.
Clean the sensor area and check for debris or damage.
Measure the sensor’s resistance using a multimeter; it should be within manufacturer specifications (typically around 1,000 ohms).
If faulty, replace the sensor with a new one.

3. Check ABS Fuse

Locate the fuse box and identify the fuse related to the ABS system.
Remove the fuse using a fuse puller.
Inspect the fuse visually; if broken, replace it with a fuse of the same amperage rating.

4. Inspect ABS Control Module

Locate the ABS control module, usually near the master cylinder.
Check for any visible signs of corrosion on the connectors.
Disconnect the module and inspect the wiring for breaks or shorts.
If necessary, replace the ABS control module with a compatible unit.

5. Reassemble and Test

Reconnect all components and wiring harnesses.
Reinstall the wheels and lower the vehicle.
Reconnect the battery.
Clear any diagnostic trouble codes using the OBD-II scanner.
