Service Engine CODE !

Hi, I do the procedure to extract the service engine code from the computer.
When the light begins to flash here's what is the code extract ;

12473155

Wich number is the code, I saw a lot with 2 numbers, but 8 numbers !!!

Thanks for your help.

12 is start 55 is end of codes. The codes you have are actually 47 and 31. Code 47 indicates low charging circuit voltage, check the alternator, wiring to the alternator or the belt. Code 31 indicates you have a problem with the evaporative emissions circuit. You could have a loose gas cap or a bad solenoid on the evap. emissions system. I hope this clears it up.

Here is the link for the fault codes for 80 amd 90's Chryslaer, Dodge and Plymouths. http://www.allpar.com/fix/80s-codes.html
Hope it helps you out.

Thanks everybody, it helps me very much !
