I fried my 16147060 pcm with the wrong wires idiot me.
Luckely I have a backup, but inside some ic is burned and if I can find the corecyt one I may be able to repair it.
However it is pretty fried so I can read half the numbers so I need to know exact what numbers are on it.
In this picture it is the black ic with 9 legs between the 2 aluminum blocks and the bolt ,
If someone has a spare would you mind looking inside and tell what numbers are on it ?
What I have so far is:
3499*
037D5
466







Your help is much apreciated

 

you might check for the information on gearheadefi.com It looks like the ecm is similar to the 16197427

 

But is that the only damage? Even if you could get the chip what was on it?

It may be hard in Netherlands to get a used PCM but here not so, any auto part store. Or even with an early E trans PCM like this at a junkyard for $20-$30. Worse case eBay.

Then there's always an option of wiring on new pigtails and using an ever abundent 16197427...

With how cheap these ECM/PCM are here I don't think anyone would try and repair one.

 

Very true about you junkyards, but they are not here, aldough I bought a used 4l80e with diesel ecm and loom for a steal overhere.
I am used to try to fix everything I break......
It is possible that something else is fried inside, dont know.
Gues I keep it as a spare parts box.

 

That chip is the IAC driver. For an off the shelf chip, look for a bi-polar stepper motor driver. Likely made by Texas Instruments.

Otherwise, that chip is used in many different ECMs, even the early '7747 uses it. If you wired +12 volts to the IAC wires it may be just the chip that popped.
