I first tried to read through 16-pin OBDII but i cannot get it to read. Its a 2018 Isuzu NPR with 3 plug denso GEN2. I have Module 69(087) and idk if i have pinout wrong but i cannot get it to read. So i pulled ECU and now have it on bench. im unsure if i have it pinned correctly, but i can get it to see module with device tester and also identify in mmc flash with a different module number. It also it asks to key off with master switch but i do not have a switch or know which pin is for key off/on. any advice would be great or proper pinout possibly. Also maybe i need special harness? i am also using USB link 3 which supports J2534. I can get it read ecm info under the Denso SH7059 (Module 82 section) but i know 1536k is not correct size for this ecu.
Here is what it identifies under Denso SH7059 CAN (Which is wrong):
[Adapter name] NEXIQ Technologies - USB-Link 3 USB

[18:14:01] Hardware Part Number: 98392463

Here is when i try to read with correct module 82
[Adapter name] NEXIQ Technologies - USB-Link 3 USB
[Firmware version] 0.017654
[Dll version] 3.2.1.6
[18:05:25] Error: no response from ECU. Check contacts and additional devices on bus, such as anti-theft alarm system., code: 0000
Any ideas on what im doing wrong? Possibly get correct pinout, or what adapter is needed?
Thank you
