P0505 ecm/iac

[Infiniti_i30]

Hi All, new to the forum... How do I get my hands on a wiring diagram for an ECM? I need to test whether there is power coming into the ECM, or if the ECM itself is burned out. I got a rehabbed ECM off of Ebay from a memeber with 6000 sells and a near 100% feedback. I have an Infiniti 2001 I30T. I am dealing with that known P0505 error with the IAC/ECM. Where both have to be replaced or the ECM burns out again.


I think that I have the correct correct ECM, though I dont believe that it is OEM.
This is the one I purchased off of Ebay.

I contacted the seller and gave him my VIN(JNKCA31A51T014283), and he assured that it was the correct ECM for my car.

So I replace the IAC and the TPS, use die electric grease on all the sensers, and clean the throttle assembly with throttle cleaner. I put this rehab ECM from ebay into the car and have it towed off to the dealer. They say that they can see the other computers onboard with their scanner(ABS, transmission) but cant see the ECM in order to the Idle relearn and reprogram the ECM.

Thanks for your help in adance, any questions please let me know.
