it means to service soon !!!! car ecu has a count down timer ,,, if it wasnt reset at last service it thinks a service is due ,make sure its reset every service so you can service at right intervals

Try code from service provider..............

It means it is due for service. just service it and it will go off.

Means they either didn't fix a problem or caused one.
