I know Y83 is "New car service" but can't find Y84?

No-one seen this code before then?

Y85 is also new carservice with 0 gal gas. Not sure on Y84. Sorry Dave

Y84 is NCS (New Car Service) Dealer Pre-Service. I would think that some dealers preferred to do their own NCS to save the factory charge and ordered their cars this way.

Thank you Jack!
