How to check "diagnostics codes" on 1999 T&C?

Hi,

I heard other posters mentioned checking "diagnostics codes".
How could it be done on 1999 Chrysler Town & Country?
I have what seems to be output speed sensor problem, but
wanted to check diagnostics code to make sure.

Thanks,
IP.

You can (I believe) do the key on off on trick and watch the odometer. I
believe though it only schows codes from the pcm not the tcm or bcm. You
need a very expensive reader to get into the tcm.
