3. Check and Address Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Scan for any trouble codes and note them down.
Clear any codes present and attempt to use the remote start again.
If error codes return, investigate the corresponding issues (e.g., sensor failures).

4. Inspect Security System

Ensure all security features are functioning properly (e.g., doors lock/unlock correctly).
If issues are detected, consult the vehicle’s manual for troubleshooting specific to the security system.

5. Verify Vehicle Conditions

Confirm that the vehicle is on a flat surface and not in a location that may obstruct starting (e.g., within a garage with insufficient ventilation).
Attempt to start the vehicle remotely again.
