My question is related only to the drivers and how to test them and what signals they need and also the pin identifications (B+,Gnd,Out,etc)
Yup it took me more than a week to remove most potting compound. The ecu on this elantra is located on the upper left hand of the firewall beside the TCM inside the cabin. Good thing that at 62 years old I can still contort my body to reach the mounting bolts. The corolla I am working on has the ecu on the center console under the AC box. And no potting or encapsulating compound. Very easy to access but also easy to get wet. We encounter very severe flooding here during the rainy season. Water and electronics equals kaboom!! LOL.
I have another question. What type of trigger signal does the ecu inject into the driver ic? Maybe I can use discreet components like transistors to drive the coils. I will house them in a box outside the ecu like old time efi and use only the trigger signals from the ecu. Can you point out the pins on the ic where the signals come in? Is it safe to assume that there are other coil drivers that can be substituted? Maybe the 976 has a substitute.
I registered at the ST Micro website and submitted an online request regarding the correct catalog part no. and or substitute just in case this is out of production.
Maybe free samples? (fingers crossed) LOL!!
By the way. The second link (http://www.st.com/web/en/search/partNumberKeyword) does not work.
