Solution
1. Preparation
  • Tools Required: OBD-II scanner, multimeter, socket set, torque wrench
  • Ensure the vehicle is parked on a flat surface, and the ignition is turned off before beginning work.
  • Disconnect the battery to ensure safety while handling electrical components.
2. Scan for Error Codes
  • Use the OBD-II scanner to retrieve any diagnostic trouble codes (DTCs).
  • Record the codes and proceed to diagnose the issues indicated.
3. Inspect ABS Wheel Speed Sensors
  • Locate each wheel speed sensor near the brake assembly.
  • Check for signs of physical damage, dirt, or disconnection.
  • Clean any dirt or debris from the sensors and connectors.
  • Reconnect any loose connections.
4. Check ABS Module and Wiring
  • Inspect the ABS module for any visible damage or corrosion.
  • Check the wiring harness connected to the ABS module for frays or disconnections.
  • Use a multimeter to check for continuity in the wiring.
5. Inspect Brake Fluid Level
  • Open the hood and locate the brake fluid reservoir.
  • Check the fluid level; if low, top off with the recommended brake fluid (DOT 3 or DOT 4 as per manufacturer's specifications).
  • If the fluid is contaminated, perform a brake fluid flush.
6. Test Brake Pedal Switch
  • Locate the brake pedal switch and check its operation.
  • Ensure the switch is engaging and disengaging properly when the pedal is pressed.
  • If faulty, replace the brake pedal switch.
7. Test ABS Pump
  • If all previous steps are clear, use the scanner to perform a functional test of the ABS pump.
  • Listen for the pump operation and ensure it activates as expected.
