Solution
1. Preparation
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect and Replace Wheel Speed Sensors
  • Tools Required: Socket set, multimeter, torque wrench
  • Locate the wheel speed sensors on each wheel hub.
  • Use a socket set to remove the mounting bolts and disconnect the electrical connector.
  • Check the sensor resistance with a multimeter; it should match specifications in the service manual.
  • If faulty, replace the sensor with a new one, ensuring alignment and proper sealing.
  • Reattach the electrical connector and secure the sensor with the bolts (torque to manufacturer specifications).
3. Check ABS Module and Traction Control System
  • Tools Required: OBD-II scanner, multimeter
  • Reconnect the negative battery terminal.
  • Use an OBD-II scanner to clear any existing codes.
  • Check ABS module connections for corrosion or damage.
  • Use a multimeter to test the ABS module's power and ground connections.
  • If the ABS module is defective, replace it according to the service manual.
4. Verify Brake Fluid and Tire Condition
  • Check the brake fluid level and top up with manufacturer-recommended fluid if necessary.
  • Inspect all tires for proper inflation and tread wear; replace if they are worn or below the recommended pressure.
