Tools Required: OBD-II scanner, multimeter, socket set, wire stripper/crimper, and safety gloves.

2. Address Faulty Components

Identify Faulty Component: Based on diagnostic results, determine which component is malfunctioning.
Remove Component:
- Disconnect any connectors carefully.
- Use the socket set to remove any screws or bolts securing the component.
Inspect and Replace:
- Check the component for physical damage or wear.
- If needed, replace with a new component ensuring it meets OEM specifications.

3. Repair or Replace Wiring

Locate Damaged Wiring: Use visual inspection or multimeter to find damaged wires.
Cut and Strip Wires: Cut out any damaged sections and strip insulation from the wire ends.
Reconnect Wires:
- Use wire connectors to join the wires securely.
- Ensure proper insulation with electrical tape or heat shrink tubing.

4. Reassemble and Test
