9-5 Indecisive Service Indicator?

[otolith]

Odd - the Saab decided last week that it would quite like a service, and said so via the SID. This stayed there for a few days, and then vanished. I'm assuming that it should keep demanding a service until it is reset? It is also a bit of a fantasist, occasionally coming up with spurious claims of headlights or foglights not working.

If its like mine i think it resets after a number of engine starts. I think its about 20.

That would explain it, though seems a bit of an odd design decision. I'd expect it to change the message to "Busting for a service now"
