Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the vehicle's 12V battery to avoid electrical hazards.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, Torque wrench, Multimeter, Pliers
Sub-steps:
1. Remove the wheel corresponding to the faulty sensor (consult the service manual for specific torque values when re-installing).
2. Disconnect the electrical connector from the wheel speed sensor.
3. Remove the sensor from its mounting location, taking care not to damage surrounding components.
4. Install the new wheel speed sensor and secure it with the appropriate torque.
5. Reconnect the electrical connector and ensure it is firmly attached.

3. Repair Wiring and Connectors

Tools Required: Wire strippers, Electrical tape, Soldering iron (if needed)
Sub-steps:
1. Inspect the wiring harness for frays or breaks; repair any damaged wiring using solder and heat shrink tubing or electrical tape.
2. Clean and reconnect any corroded connectors, ensuring a secure fit.
3. Use a multimeter to check continuity of the wiring from the ABS module to the wheel speed sensor.

4. Reconnect Battery and Clear Codes

Reconnect the 12V battery.
Use the OBD-II scanner to clear the C0241 code.
Perform a recalibration of the ABS system if required by the vehicle's service manual.
