Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety during repairs.

2. Retrieve and Analyze Diagnostic Codes

Reconnect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Record the error codes indicated by the scanner and interpret based on service manual or online resources.

3. Address Identified Issues

For check engine codes, refer to the specific code(s) to determine necessary repairs (e.g., replacing faulty sensors, fixing leaks).
If tire pressure monitoring system (TPMS) light is on, check tire pressures and reset the system if all tires are inflated correctly.
For ABS issues, inspect wheel speed sensors and brake fluid levels, replacing components as needed.

4. Clear Error Codes

With the OBD-II scanner, select the option to clear error codes after completing necessary repairs.
Confirm that the dashboard lights have turned off.

5. Reconnect Battery

Reconnect the vehicle battery, ensuring terminals are tight and corrosion-free.
Start the vehicle and observe the dashboard for any reappearance of warning lights.
