my Tesla Model 3 Original (2017-2023) has a C0030 error code what does it mean

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, cleaning supplies.
• Ensure the vehicle is parked on a level surface and the ignition is off. Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

• Sub-steps:
  1. Raise the vehicle using a hydraulic jack and secure it with jack stands.
  2. Remove the wheel corresponding to the affected sensor.
  3. Locate the wheel speed sensor; it is typically mounted near the brake rotor.
  4. Disconnect the sensor's electrical connector.
  5. Clean the sensor and the mounting area with a suitable cleaner to remove dirt and debris.
  6. Reconnect the sensor and ensure the connector is secure.

3. Replace Wheel Speed Sensor (if necessary)

• Sub-steps:
  1. If the sensor is damaged or the resistance is out of specification, remove the mounting bolt(s) securing the wheel speed sensor.
  2. Carefully pull out the old sensor and replace it with a new one.
  3. Torque the mounting bolt(s) to the manufacturer’s specifications (generally around 10-15 Nm).
  4. Reconnect the electrical connector securely.

4. Reconnect Battery and Reset Error Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the C0030 error code.
• Start the vehicle and check if the ABS and traction control lights are off.
