Safety Warnings

  • ⚠Always disconnect the battery before working on electrical components.
  • ⚠Allow the vehicle to cool before handling brake components or sensors.

Symptoms

  • •ABS warning light illuminated on the dashboard
  • •Traction control warning light activated
  • •Loss of ABS functionality during braking
  • •Unusual noises from the ABS pump module
  • •Increased stopping distance under hard braking conditions

Diagnostic Steps

  1. 1Scan the vehicle's OBD-II system using a scanner to confirm the C0210 code and check for any additional trouble codes.
  2. 2Visually inspect the wheel speed sensors for damage, dirt, or corrosion.
  3. 3Check the wiring and connectors related to the wheel speed sensors for any signs of wear or disconnection.
  4. 4Measure the resistance of the wheel speed sensors using a multimeter to ensure they are within the manufacturer’s specifications.
  5. 5Inspect the ABS control module for proper operation and any signs of failure.
  6. 6Clear the trouble codes and perform a test drive to see if the code returns.

Solution

Solution

1. Preparation

  • Gather necessary tools and safety equipment.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

  • Locate the wheel speed sensors at each wheel hub.
  • Remove any debris or dirt from the sensor area using a clean cloth.
  • If corrosion is present on the connector, clean it with an electrical contact cleaner.

3. Repair or Replace Faulty Wheel Speed Sensors

  • If a wheel speed sensor is found to be faulty (based on resistance measurements), remove the sensor by:
    1. Unscrewing the mounting bolts using a socket set.
    2. Disconnecting the electrical connector.
  • Install the new wheel speed sensor:
    1. Connect the electrical connector securely.
    2. Torque the mounting bolts to the manufacturer’s specifications (typically around 8-10 Nm).

4. Inspect ABS Control Module

  • Check the ABS module connections for corrosion or damage.
  • If necessary, replace the ABS control module by:
    1. Disconnecting all wiring harnesses.
    2. Removing mounting bolts with a socket set.
    3. Installing the new module and reconnecting all wires securely.

5. Reconnect Battery and Test

  • Reconnect the negative battery terminal.
  • Clear the C0210 code using the OBD-II scanner.
  • Start the vehicle and perform a test drive to ensure the ABS system is functioning correctly.

Verification
