re-setting ECU to cancel trouble codes???b

[bgambino]

well.....I didn't get much of a response to my trouble code(s) problem on my last post.....I am going to search for grounds and clean them and maybe run a direct ground from battery to body......but does anyone know how to wipe out the system and start fresh.....simple explanation please;-)

thanks

Bill, need to know what year and model you have.

 

The method is to plug the two sets of diagonostic

connectors (one set is green, the other set is black or white -depends on car fuel system) together and turn on the ignition.

 

Location of said connectors is also fuel system dependant.

 

Please read all about here

Note: If a problem still exists (i.e. egr solenoid winding open) the ECU will not clear the code.

 

hope this helps

sorry skip---that was a stupid omission---91 loyale 4wd auto. non-turbo wagon----I read the link---says to connect the 2 connectors near the ECU (unless they are somewhere elese on my model)---I hope there are ONLY 2 in that location...?

Bill, thanks for the info

 

You car will be a SPFI model

(Single Point Fuel Injection)

 

The connectors in question will be under the hood

near the drivers side hood hinge (assuming it to be a American car i.e. left hand drive)

 

Hope this helps.

Here is another link to book mark

thanks Skip...it IS an American.....on the links, I see nothing that directs me to the conn's being under hood...only references to under dash...did I miss that point?

Bill, this quote is taken from the second link

"On carberated and SPFI injected 89 models,the test connectors are located on the engine side/driver's side of the firewall."

 

Your car fits this description as it is the same as an 89.
