Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake fluid.
• Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the negative battery cable to prevent electrical shorts.

2. Address Fault Codes

• Sub-steps:
  1. Connect the OBD-II scanner to the vehicle's diagnostic port.
  2. Retrieve and document any ABS-related fault codes.
  3. Clear the codes and monitor if they reappear after a test drive.

3. Inspect and Replace Components

• Sub-steps:
  1. Check the ABS fuses located in the fuse box under the dashboard and in the engine compartment.
  2. Replace any blown fuses with the same amperage rating.
  3. Inspect the ABS wheel speed sensors mounted at each wheel. Clean or replace them if damaged or dirty.
  4. If necessary, replace the ABS control module by unbolting it, disconnecting the wiring harness, and installing the new module. Torque bolts to manufacturer specifications.
