Subiguy1 Posted July 13, 2023 Report Share Posted July 13, 2023 Recently got installed my ecu and im unable to connect to it with laptop i have confirmed the driver is there but im getting no luck Quote Link to comment Share on other sites More sharing options...
Subiguy1 Posted July 13, 2023 Author Report Share Posted July 13, 2023 Upon further inspection, I’ve found something missing on the board?? Or is this normal. If this isn’t normal do I contact the dealer I got the ecu from or tech support? I’m located in hawaii Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 14, 2023 Report Share Posted July 14, 2023 No thats not normal, it looks like it has had a mis-soldered component that eventually got bumped off. Contact [email protected] to get it replaced or fixed. However, that missing cap is only part of the decoupling before the 5V regulator, it will not prevent the ecu from connecting or working, so I suspect this to be more a coincidence rather than your actual problem. We should do a bit more diagnosis first. Do you have blue LED's glowing with the ecu plugged in and ignition on? Quote Link to comment Share on other sites More sharing options...

No the blue led is not light up, there is power coming though the harness itself Edited July 14, 2023 by Subiguy1 Missing reply Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 14, 2023 Report Share Posted July 14, 2023 I wonder if you have the USDM hitachi ecu pinout. Do you have 12V on pin B19 with the ign switch on? Quote Link to comment Share on other sites More sharing options...

Yes I have power to that pin, would the hatachi harness header be the same as a denso? 1 minute ago, Subiguy1 said: Yes I have power to that pin, would the hatachi harness header be the same as a denso? I looked up the ecu number on the board it self ecu 112431-2290 and got denso ecus Quote Link to comment Share on other sites More sharing options...
Subiguy1 Posted July 14, 2023 Author Report Share Posted July 14, 2023 Okay i think i may have figured it out and im at a lost, according to the manual A7/B2 does not have any pinouts on the Harness it self... Im guessing not all densos are compatible with this ecu.. Is there a way around this? to still use the ecu dont want to just waste $1500+ Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 14, 2023 Report Share Posted July 14, 2023 The USDM denso pinout changed in 2011 so I think that is what you may have there. Get your dealer to get in touch with Link, they will possibly refund it. I believe the >2011USDM pinout is quite different to the rest of the world, the only way to make it work would be to repin the harness or get someone to make an adapter loom.
