Use a multimeter to measure the vehicle battery voltage.
If voltage is below 12.4 volts, charge or replace the battery.
Ensure battery terminals are clean and securely connected.

4. Inspect Security System

If error codes indicate a security system issue, reset the vehicle’s security system by disconnecting the negative battery terminal for 15 minutes and reconnecting it.
Check the fuses related to the remote start and security system; replace any blown fuses.

5. Verify Remote Start Activation

After completing the above steps, attempt to activate the remote start feature again.
Ensure doors and hood are closed, then press the remote start button twice within three seconds.
