Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery (-) terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from around the sensors using a clean cloth.
If necessary, disconnect the sensor connectors and check for corrosion or damage.
Reconnect the sensors and ensure they are seated properly.

3. Check ABS Control Module Connections

Locate the ABS control module, usually found near the brake master cylinder.
Visually inspect the wiring harness for damage or loose connections.
Disconnect the wiring harness and clean the connectors with electrical contact cleaner.
Reconnect the harness securely.

4. Test and Replace ABS Relay

Locate the ABS relay in the fuse box (refer to the owner’s manual for exact location).
Remove the relay and use a multimeter to test for continuity.
If the relay is faulty, replace it with a new one.
Restore the relay and ensure it is seated properly.

5. Refill and Bleed Brake Fluid

Check the brake fluid reservoir and top off with the manufacturer-recommended fluid (usually DOT 3 or DOT 4).
If necessary, bleed the brakes to remove air from the system, using a brake bleeder kit.
Ensure all connections are tight and free from leaks.

6. Reconnect Battery and Clear Codes

Reconnect the battery (-) terminal.
Use the OBD-II scanner to clear the C0241 code and any other stored codes.
Start the vehicle and verify that the ABS light has turned off.
