Hi,

If you look below, pic 1 shows the two connectors at the ECM. The remaining pictures are the pinouts for them.

Let me know if this helps or if you have questions.

Take care,

Joe

Thanks, JACOBANDNICKOLAS for your response, but this doesn't match my need. What I need is for a Bosch EDC17CV41 ECU on 4 cylinder 3.0L 4jj-1 motor that's the picture below, please help if you have.

Hi,

That is the only one I'm finding for the Reach. My manual provides one engine possibility and one ECM possibility. Could it be listed under something different?

With the VIN, I get different information. I attached it below. Let me know if that is what you need or if that is incorrect as well.

Take care,

Joe

This pin-out looks like it correspondents with my ECU pin numbers, but can I get the ECU wiring diagram to further check? Because the vehicle is far away from me, I'll be going there by next week and I need to gather all necessary information.

I also need to add that I'm new to Isuzu troubleshooting so I'll need you to answer this question: is it possible to perform Adblue off using idss or other special development tool like I can on other European trucks which I'm specialize in like Daf, Volvo, MAN, and Mercedes this is a US isuzu and we don't have much experience with US isuzu I have g-idss but not good with this Isuzu truck. Thank you very much JACOBANDNICKOLAS for your assistance.

Hi,

I attached what I have based on VIN. Take a look and let me know if they help.

As far as your second question is concerned, I'm not familiar with the vehicle. The only way I'm getting info is with your VIN.

Let me know.

Joe

Yes, the diagram seems helpful, but looks like a 121 ECU pin and not a 96 ECU pin like the pin-out you sent earlier. Pictures appear to be blurry, I can't see those ECU pin numbers clearly, can you confirm and resend?
Thanks for your help.

Hi,

Unfortunately, the schematics are factory, and they aren't that clear. That is what came up with the VIN. I hope it is correct and helpful.

Let me know.

The schematics don't match in any way you can confirm this yourself. But if that's all you have, it's fine thanks for your time and effort.
