Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle battery to ensure safety while working on electrical components.
2. Inspect and Clean Wheel Speed Sensors
  • Locate the wheel speed sensors at each wheel hub.
  • Remove any dirt and debris from the sensor and surrounding area using a soft brush or cloth.
  • Check the sensor connector for corrosion and ensure a secure connection.
3. Check ABS Control Module
  • Reconnect the battery and use an OBD-II scanner to read ABS fault codes.
  • If codes indicate a malfunctioning ABS module, proceed to replace it.
  • To replace the ABS module, disconnect the battery, remove the module from its mounting bracket, and disconnect the wiring harness.
  • Install the new module and reconnect the wiring harness and battery.
4. Inspect Brake Fluid and Pump
  • Check the brake fluid reservoir for the correct fluid level; top off if low.
  • If the fluid is contaminated, flush the brake system and replace with fresh fluid.
  • Test the brake pump for functionality if the fluid level is adequate.
5. Verify Wiring Connections
  • Inspect all related wiring harnesses and connectors for wear, damage, or corrosion.
  • Repair or replace any damaged wiring or connectors.
  • Ensure all connections are secure before reassembling components.
