ok I finally got around to checking my ecu in my 87 SE...and I went into mode three and checked the codes...I got code 2(red) and 1(green)...has anyone gotten this code before and if so what did you have to fix/replace? Also when checking the ecu do you need to check all five modes? Thanks.

does anyone know this one?

 

From the Haynes manual:

Code 2r, 1g = Ignition signal...The ignition signal in the primary circuit is not entered during engine cranking or running. (This repair must be performed by a dealer service department.)

 

Thanks for getting back to me, but I already have the haynes manual so I know what it says...but I am wondering what the means? Does anyone know what kinda malfunction causes this code to be thrown (i.e. what part went out)...thanks

 

Uhhhhh, Okay...

The part that stands out to me is, "This repair must be performed by a dealer service department."

I would hazard a guess that it means it isn't a do-it-yourself problem.

 

Thats fine...the dealership may need to fix it but I am just trying to get an idea of what has gone bad in the car, thats why I was seeing if anyone else has ever had this code

 

hmmm, if there's a failure in the ignition circuit, your car will be having a hard time running. I would clear the code from the ECU, drive it around a bit and check again for the code and see if it comes back, remember, if you can't recreate the problem, you don't have a problem. I know on 85-86 ECU's, they require that you operate a few things or else codes will pop up, like the TPS switch, and the load circuit. Could be that since the motor isn't running when you pull the code that it throws off that code. I would make sure you have the diagnosis process down first to make absolutely sure it wasn't an error by you when checking for the codes.

where can i find a code reader to check my codes? i know autozone has them but they are really expensive like $50 if anyone knows i would greatly appreciate it

 

Umm, a Chiltons/Haynes/FSM will tell you how to read the codes.
