Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (sockets, wrenches), brake cleaner.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect ABS Wheel Speed Sensors

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake components.
3. Locate the ABS wheel speed sensor mounted on the brake assembly.
4. Disconnect the sensor's electrical connector.
5. Clean the sensor tip and the area around it with brake cleaner.
6. Reconnect the electrical connector and reassemble the wheel.

3. Check ABS Module and Connections

Sub-steps:
1. Locate the ABS control module under the hood.
2. Inspect the module for any visible signs of damage or corrosion.
3. Using a multimeter, check the input voltage and ground at the ABS module connectors (refer to wiring diagrams for specifics).
4. Replace any frayed or damaged wiring as necessary.

4. Replace Faulty Components

Sub-steps:
1. If the OBD-II scanner indicated a specific faulty wheel speed sensor, remove the old sensor by unscrewing it from its mount.
2. Install the new sensor by securing it to the mount and reconnecting the electrical connector.
3. If the ABS module is faulty, remove it by unscrewing the mounting bolts and disconnecting the wiring harness.
4. Install the new ABS module, ensuring all connectors are secure.
