Turn the ignition to the ON position without starting the engine.
Follow the scanner instructions to read and record any trouble codes.
Disconnect the scanner after recording.

3. Inspect and Repair Identified Issues

For Check Engine Light:
- Consult the trouble codes to identify the specific issue (e.g., O2 sensor, misfire).
- Replace faulty components as indicated by the codes and clear the codes using the scanner.
For ABS Warning Light:
- Check brake fluid level; refill if low.
- Inspect the ABS module connections and wiring for damage.
- Replace any faulty ABS sensors as indicated by diagnostic codes.
For Battery Warning Light:
- Test the battery voltage using a multimeter; replace the battery if voltage is below 12.4V.
- Clean battery terminals and ensure they are tightly connected.
For Cruise Control and Stability Control Warnings:
- Check for any fault codes related to the cruise control module.
- Inspect the vehicle's speed sensor and replace if necessary.

4. Final Assembly

Reconnect the negative terminal of the battery.
Start the vehicle and check if the warning lights have cleared.
If lights remain illuminated, conduct further diagnostics based on new codes.
