what does it mean if my Volvo XC60 has a C0035 code

Solution

1. Preparation

• Gather the following tools: OBD-II scanner, multimeter, socket set, torque wrench, wire brush, and dielectric grease.
• Disconnect the negative battery terminal to avoid any electrical shorts.

2. Inspect and Replace Wheel Speed Sensor

1. Remove Wheel

   • Loosen lug nuts while the vehicle is on the ground.
   • Raise the vehicle using a jack and secure it with jack stands.
   • Remove the wheel.

2. Remove Old Wheel Speed Sensor

   • Locate the left rear wheel speed sensor mounted at the wheel hub.
   • Disconnect the electrical connector from the sensor.
   • Remove the retaining bolt using the socket set and carefully pull the sensor from the hub.

3. Install New Wheel Speed Sensor

   • Apply dielectric grease to the new sensor’s connector to prevent corrosion.
   • Insert the new sensor into the hub and secure it with the retaining bolt, torqueing it to manufacturer specifications (typically around 8-10 Nm).
   • Reconnect the electrical connector.

3. Reassemble and Test

1. Reinstall Wheel

   • Place the wheel back onto the hub and hand-tighten the lug nuts.
   • Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specifications (usually around 100-120 Nm).

2. Reconnect Battery and Clear Codes

   • Reconnect the negative battery terminal.
   • Use the OBD-II scanner to clear the C0035 code and any other related codes.

3. Test Drive

   • Conduct a test drive to ensure the ABS and traction control systems are functioning properly and that the warning lights are not illuminated.
