98 Caravan Service engine codes 12177255?

Hello Dodge Drivers!

My 1998 Dodge Caravan flashes the "Service Engine Soon" code of 1-2-1-7-7-2-5-5.
Anyone know what that refers to?

Thanks!

If this is a 3.0L with a 3 speed trans, 12 is start of test, 17 engine cold too long, 72 is really code 37 TCC no rpm drop if its a 3 speed trans and 55 end of test.
