Intruments totally breakdown 850 1996


Instrument panel totally breakdown, no odo, no speed only the clock and the lights work. No communication with the service tester possible. Power supply seems to be okay. Maybe the microprocessor is damaged. Any ideas or hints or similar problems ?

Regards,
Curt

I have the same problem but don't have the time to get my hand dirty yet.
The possibilities are: The speed sensor on top of tranny, or the microprocessor in the dashboard that is broken. Get a code reading to be sure.
Mine is still picking up speed for the first half hour driving before it stays put.
