  3. Disconnect the wiring harness from the wheel speed sensor.
  4. Inspect the sensor for dirt or damage; clean with brake cleaner if necessary.
  5. Reconnect the sensor and wheel.

3. Check and Top Off Brake Fluid

• Sub-steps:

  4. Close the reservoir cap securely.

4. Inspect and Repair ABS Control Module

• Sub-steps:
  1. Locate the ABS control module, typically near the master cylinder.
