Anyone taking the DIC apart to see whats inside? I noticed that there are a number of screws on the underside of the cassette. My car has a P0327 code which relates to the knock sensor. It could be a broken lead or bad connection inside the DIC but is it accessible is the question.

I've taken one apart. There's just a lot of black epoxy type stuff covering up all the internals. I'm sure it's just a bunch of capacitors and circuitry.

The Haynes manual has a DIC disassemble section. It's not really considered a serviceable component. I would just buy a new or lightly used one, version 3.7 or higher.

I thought it was full of magic smoke and leprechauns. Let any of that out, it stops working.

Yeah, like others have said, you can take the 'nipples' off the DIC and you see a large area that has caps and a bunch of electronics all sealed into their individual coils.

These generally fail for two reasons: The oil that cools these slowly disappeared, or leaked out, so they overheat somewhere.

Or you crack the nipples/boots on the bottom half, and the spark arches out where it shouldn't.

If you have broken boots, even a small crack, it's a good chance that's why it stopped working / started misfiring.

I've taken a few salvage ones and swapped boots around to make a few working spares, and had success. But if the internals are screwed, you're in the market for new/used parts =)

What sucks is that my car is still running good. It is just annoying to have to look at the check engine light all the time. When I changed the plugs I didn't notice any leakage from the boots.
