Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench
Sub-steps:
1. Raise the vehicle and remove the wheel corresponding to the faulty sensor.
2. Locate the ABS wheel speed sensor on the wheel hub assembly.
3. Disconnect the electrical connector from the sensor.
4. Remove the sensor from its mounting location using the appropriate socket.
5. Install the new wheel speed sensor and secure it to the hub.
6. Reconnect the electrical connector ensuring it clicks into place.
7. Torque the sensor mounting bolt to the manufacturer's specifications.

3. Check and Repair Wiring

Tools Required: Wire crimping tool, electrical tape, multimeter
Sub-steps:
1. Inspect the wiring harness leading to each ABS sensor for frays or cuts.
2. If any damage is found, use the crimping tool to repair the wiring.
3. Wrap repaired sections with electrical tape to prevent moisture ingress.

4. Reconnect Battery and Clear Codes

Sub-steps:
1. Reconnect the negative terminal of the battery.
2. Use the OBD-II scanner to clear the C0241 error code from the system.
3. Start the vehicle and check if the ABS warning light is still illuminated.
