Hi, im troubleshooting a no-start problem, and have my ECU pulled out and disasembled. I have found that one of the 14-prong soldered chips has a piece of solder bridging two of the legs....but it seems like they are supposed to be like that possible.
now, before i remove the solder, id like to look at a diagram of the board, does anyone know where to find a diagram?
My ecu has the following numbers on the sticker:1730575 001
I believe people refer to it as the "173 ecu" Anyone know what to call it properly so i can search the web for the proper diagram?
HERE are the pics of the ECU
Thanks in advance,
