I'm GW. I'm not showing that code in any of my info databases. Can you run the test again?
Customer: replied 8 years ago.
On the Check Engine Light Code site it came up, I did it before and I thought it was DTC 25. But I did it again and it was DTC 12 then DTC 55.
Expert:  Golden Wrench replied 8 years ago.
OK. What size engine.
Customer: replied 8 years ago.
V6 engine
Expert:  Golden Wrench replied 8 years ago.
OK. On the earlier models to 1994(your vehicle inclusive) code 12 means the battery power has been removed within 50 key cycles. Code 55 is an end of code reading session code. Seems like all is well with this vehicle. Are you experiencing any symptom related problems?
