how to diagnose C0035 code in Volvo XC60 First Generation (2008-2017)

Solution

1. Preparation

• Gather tools and parts required.
• Ensure the vehicle is parked on a level surface and secured with wheel chocks.
• Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensor

1. Remove the Wheel:

   • Use a jack to lift the vehicle and secure it with jack stands.
   • Remove the lug nuts with a socket set and take off the left front wheel.

2. Access the Wheel Speed Sensor:

   • Locate the wheel speed sensor mounted on the left front wheel hub assembly.
   • Remove any mounting bolts or clips holding the sensor in place.

3. Check Wiring and Connector:

   • Inspect the wiring harness leading to the sensor. Look for any signs of wear or damage.
   • If the connector is corroded, clean it with electrical contact cleaner.

4. Replace the Sensor (if faulty):

   • Disconnect the old sensor from the wiring harness.
   • Install the new sensor by reversing the removal steps.
   • Ensure it is securely mounted and the connector is firmly attached.

3. Reassemble and Reconnect

1. Reattach the Wheel:

   • Place the wheel back onto the hub and hand-tighten the lug nuts.
   • Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

2. Reconnect the Battery:

   • Reconnect the negative terminal of the battery.

3. Clear Diagnostic Codes:

   • Use the OBD-II scanner to clear the C0035 code from the vehicle’s computer.
