Solution
1. Preparation
  • Ensure the vehicle is parked on a flat surface and the engine is off.
  • Disconnect the negative terminal of the battery to prevent electrical shorts.
  • Gather tools and parts needed for inspection and repair.
2. Inspect ABS Wheel Speed Sensors
  • Locate the ABS wheel speed sensors at each wheel hub.
  • Remove any debris or dirt from the sensor area.
  • Disconnect the electrical connector and check for corrosion.
  • Use a multimeter to test the resistance of the sensor; replace if out of specifications.
3. Check Brake Fluid and Lines
  • Remove the brake fluid reservoir cap and check the fluid level; top off with the manufacturer-recommended brake fluid if low.
  • Inspect all brake lines for leaks or damage; replace any damaged sections.
  • Refill the brake fluid reservoir if necessary and ensure the cap is securely replaced.
4. Examine ABS Control Module
  • Locate the ABS control module, usually found near the master cylinder.
  • Inspect for any physical damage or corrosion on the module connectors.
  • Clean the connectors with electrical cleaner and ensure a tight fit.
5. Test ABS Pump and Relay
  • Locate the ABS pump and relay in the vehicle’s fuse box.
  • Use a multimeter to check for voltage at the relay when the ignition is in the ON position.
  • Replace the relay if there is no voltage; test the pump by applying direct voltage to see if it activates.
6. Reconnect Battery and Clear Codes
  • Reconnect the negative battery terminal.
  • Use an OBD-II scanner to clear any stored ABS error codes.
  • Start the vehicle and check if the ABS light is still illuminated.
