Let's check to see what that code is. Your vehicle supports a customer code-read feature which lets you pull codes without a scan tool by using this little chicken dance...
Roll the key from off to on three times, leaving the key ON after the last cycle. Watch the odometer for a change from km to codes expressed in P-code format, followed by "P-done" or simply "done" when completed whether any codes were shown or not.
Having a code stored can be a positive thing since it may point us in the right direction. Check it out and let me know what you find.
