Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Disconnect the battery to prevent electrical shorts.
2. Scan for Error Codes
  • Use an OBD-II scanner to check for any ABS-related fault codes.
  • Record any codes for reference during repairs.
3. Inspect and Clean Wheel Speed Sensors
  • Locate each wheel speed sensor at the wheel hub assembly.
  • Remove any dirt or debris from the sensor area using a soft brush.
  • If damaged, replace the wheel speed sensor with a new one.
4. Check ABS Module Connections
  • Visually inspect the ABS module wiring harness for damage.
  • Use a multimeter to test for continuity in the wiring.
  • Reconnect any loose or corroded connections; replace connectors if necessary.
5. Replace ABS Relay/Fuse if Necessary
  • Locate the ABS relay in the fuse box.
  • Remove the relay and test it with a multimeter for functionality.
  • Replace the relay if it is faulty; also check the corresponding fuse and replace it if blown.
6. Reconnect Battery and Clear Codes
  • Reconnect the battery terminals.
  • Use the OBD-II scanner to clear any stored ABS fault codes.
  • Start the vehicle and check if the ABS light is still illuminated.
