2002 s40 instrument panel not working, shows "pin code"
 

tachometer, speedometer, fuel, temp, digital clock, odometer don't work/are blank on my 2002 S40. in the middle digital readout i see "pin code"
the car starts and drives fine, the radio works, power windows/doors work.

I tried restarting the engine, still the same results.

Any idea why this happened, or how to fix it?

thanks!
