what does it mean if my Tesla Model Y Current (2020-present) has a C0035 error code

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the vehicle battery to ensure safety while working on the electrical components.

2. Inspect Wheel Speed Sensors

• Remove the wheel: Use a lug wrench to loosen and remove the wheel nuts. Take off the wheel to access the brake components.
• Inspect the sensor: Locate the wheel speed sensor on the hub assembly. Check for physical damage or debris.
• Clean the sensor: If dirty, clean the sensor using a soft cloth and an appropriate cleaner.

3. Check Wiring and Connectors

• Inspect wiring: Trace the wiring from the wheel speed sensor to the ABS module. Look for signs of wear, fraying, or corrosion.
• Reconnect any loose connections: Ensure all connectors are securely attached. Repair or replace any damaged wiring as necessary.

4. Test Wheel Speed Sensors

• Use a multimeter: Set the multimeter to measure resistance. Disconnect the sensor connector and measure the resistance across the terminals of the sensor.
• Compare readings: Refer to manufacturer specifications for the acceptable resistance range. Replace any sensor that is out of spec.

5. Reassemble and Reset Codes

• Reattach wheel: Once repairs are made, reassemble the wheel and tighten the lug nuts to the manufacturer's specified torque.
• Reconnect battery: Reconnect the negative battery terminal.
• Clear error codes: Use the OBD-II scanner to clear the C0035 code from the system.
