Hello...I have a 2003 Saab 9-3 Arc with 100k miles.
I started my car and the dash keeps resetting. The car runs normally but while Im driving everything on the dashboard cuts out completely. When this happens the car is still running well and I do not lose any performance...just the gauges on the dash turn off as if the car is off. Then after 2-3 seconds it comes back on. When it comes back on the SID says "Checking system...OK. Then a couple of seconds later cuts out...comes back on...etc. Does this a few times while Im driving. If I drive it long enough it will go back to normal and wont do it anymore.
Very frustrating...I have checked the fuses and they are all good. I then disconnected the negative battery to reset the ECM. When I do this it will be fine for the rest of the day. The next morning however it will start all over again.
