Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Retrieve and Interpret Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Access the diagnostic menu and retrieve stored error codes.
Document the codes for further analysis.

3. Address Identified Issues

Based on the error codes, determine the faulty components (e.g., faulty sensors, low fluid levels).
Replace or repair the identified components accordingly. For example:
- If the check engine light is due to a faulty oxygen sensor, replace it using the following steps:
  - Locate the oxygen sensor (usually near the exhaust manifold).
  - Use a wrench to unscrew the old sensor.
  - Install the new sensor and torque it to the manufacturer's specifications.

4. Clear Error Codes

After repairs, use the OBD-II scanner to clear any error codes from the vehicle's computer.
Ensure all lights are off and monitor for any reoccurrences.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and monitor the dashboard for any illuminated lights.
Perform a short test drive to ensure no issues arise.
