Hi rios_isabel,
Thank you for the donation.
When the D4 lamp is blinking, an error has been detected by the PCM and you need to retrieve the Diagnostic Error Code.
Connect the SCS with a jumper as illustrated and turn ignition switch on. Count the flashes on the D4 lamp, long flash = 10. Short flash = 1
Let me know the code.
