What happens if you accidentally jump the datalink connector thinking it was the one to read blink codes. I noticed a small spark when I put paper clip on the data link connector. I know it goes to the Ecu. I’m hoping I did not fry the computer. Any advice would greatly appreciate.

 

Did you short the 3-pin connector?

 

Yes I did the 3 pin connector. I’m putting the engine back together had a blown head gasket. But I checked the codes after I did that and the only code it’s still throwing is for the speed sensor

 

Just curious... how do you short a 3-pin connector instead of the 2-pin connector that you are supposed to use to visually observe stored codes ?

There are two different connectors right next to each other. I thought I left the correct one sticking out from underneath floorboard so I could keep checking it as needed. But it was the data link connector. Plus it’s been years since having an older Honda. I’m used to obd2 wich everyone is I’m sure. Tomorrow I will know if she’s going to run or not. After I did that the srs light Flashed non stop, untell Idisconnected the battery. Hooked it back up and it seemed back to normal.

 

You are lucky. Your car may be okay. Drive around for awhile to make sure.

 

Probably shorted pin 1 to pin 3 of the data connector. Hopefully no damage occurred.
