Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Disconnect the negative battery terminal to prevent any electrical issues.
2. Scan and Clear Codes
  • Use an OBD-II scanner to read and record any fault codes related to the ABS.
  • Clear the codes and check if the ABS light reappears after a test drive.
3. Inspect and Replace ABS Components

  • ABS Fuse:

    • Locate the fuse box and find the ABS fuse.
    • Remove the fuse using a fuse puller.
    • Inspect for continuity and replace if blown.

  • ABS Wheel Speed Sensors:

    • Raise the vehicle and secure it on jack stands.
    • Locate the wheel speed sensors at each wheel hub.
    • Disconnect the electrical connector and remove the mounting bolt.
    • Inspect for damage; replace if necessary.
4. Check and Refill Brake Fluid
  • Locate the brake fluid reservoir.
  • Check the level and condition of the brake fluid.
  • If low, refill with the recommended brake fluid type (typically DOT 4).
  • Inspect for leaks in brake lines or around the ABS module.
5. Reconnect Battery and Test
  • Reconnect the negative battery terminal.
  • Start the vehicle and observe the ABS light.
  • Perform a test drive to ensure the ABS system is functioning correctly.
