Safety Warnings

  • ⚠Disconnect the battery before working on electrical systems.
  • ⚠Allow the vehicle to cool before working on brake components.

Symptoms

  • •ABS warning light illuminated on the dashboard
  • •Traction control light illuminated
  • •Erratic or inconsistent speedometer readings
  • •Vehicle may exhibit unusual braking behavior
  • •Reduced effectiveness of the ABS system

Diagnostic Steps

  1. 1Scan the vehicle's onboard diagnostics using a compatible OBD-II scanner to confirm the C0035 code and check for additional codes.
  2. 2Inspect the wheel speed sensors for physical damage, dirt, or corrosion at the sensor connectors.
  3. 3Check the wiring harness connected to the wheel speed sensors for any signs of fraying or loose connections.
  4. 4Measure the resistance of each wheel speed sensor using a multimeter to ensure they are within manufacturer specifications.
  5. 5Verify the operation of the ABS control module by checking for any software updates or faults.

Solution

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.

Verification

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
  • Check for any error codes or warning lights
  • Monitor the vehicle for a few days to ensure the issue does not recur
