  4. Reconnect the wiring harness securely.

4. Replace Faulty Components

• Sub-steps:
  1. If any components (like the vehicle speed sensor) were found faulty, remove the old part using appropriate tools.
  2. Install the new component, ensuring it is seated correctly and secured.
  3. Connect any wiring or connectors to the new part.

5. Reconnect Battery and Clear Codes

• Sub-steps:
  1. Reconnect the negative battery terminal.
