Then I go through the entire diagram just in case I missed something.

Oh right, don’t forget to connect everything before you continue.

Power sourcing is shorting somewhere, then to connect different power source.

Back to Autel maxisys ultra, tap “Diagnostics” > “EOBD” > “VIN Auto detect”, and I noticed there is still no CAN blue lights on Godiag GT100, during this time I double checked my connectors and realized I need to connect it to the middle connector. And we finally have some communication.

And Autel maxisys ultra decode VIN successfully and read out vehicle information.

I will search for the CKP sensor.

As you can see it is so valuable to have multitasking.

The primary issue was on vehicle the ckp sensor was sensing voltage to both the feed & the return.

With this Bench test I can rule out the issue being the ECU.
