Hi BB,

Those jumpers are for grounding pins 19 and 29 to the intake manifold. They are not meant as diagnostic port for these ECUs for any user to connect laptops, scanner or diagnostic equipment. The plated thru holes are less likely to be problematic in these ECUs. They look like "pin-head sized" solder blobs on the board. These carry low level signals between two sides of the board. They are seldom found with micro-cracks. The micro-cracks are usually found at the solder side of LH/EZK connector pins. Anyway the real culprit is still those aging capacitors.

Yes I have other ECU photos but now it seems difficult to post it on the board. Sometimes the connection would just terminate while uploading a photo. I'm using my Macbook laptop for this. Weirdly I could still use my Android phone to read the board but the photos are in Macbook. Even if I transfer them to the phone its difficult to manipulate them on that tiny screen to post it on the board.

Buying a used module is like me like saying "if repairs unsuccessful at least you could plug in the used module in order to continue using the car". I meant it as backup plan. If you have another car in the meanwhile then this isn't an issue.

I'll try to upload the photos again in the meantime.

Hope these helps,
Amarin
