I was getting a code 15 before my ignition coil died and, I installed a new distributor but, the ECU was still giving me a code 15 but, I reset the ECU and now it's just stays on when I short the service connector..
any thoughts?

 

If the CEL light stays lit while the service check connector is jumped then you have no stored codes. Your Code 15 has been cleared.

 

Awesome! thanks.
