ecu code 12

[mdjdc]

I've got a 92 loyale 2wd that runs like a top, but I'm getting a code 12 from the ECU. ( ignition circuit) No problems starting or running. What should I look at first? Any ideas will be much appreciated.

 

Thanks

Have you tried clearing the codes using this method

 

Clearing Codes

 

Codes will only clear when the faulty system or circuit has been repaired. After making the repairs, codes can be cleared by connecting 2 pairs of connectors, the "Self-diagnostic" connectors and the "Read Memory" connectors that are usually to the right of the diagnostic connectors.

 

• 
  
• Start with a warmed up engine
  
• Turn off the engine
  
• Connect both pairs of connectors
  
• Fianlly start the engine
  
• This should clear the codes.
  

 

 

NOT the battery disconnect method

Skip I hadn't tried to clear the codes yet. I wasn't sure if there was a problem witht the starter system, since she starts and runs like a champ. I will try to clear the codes and see if the CEL goes out. I guess I can chase down wome gremlins if I need to, but I need a start point. First I will see if clearing the codes gets the CEL off. If not, then i will repost.

 

Thanks
