Could be the connector towards the engine coolant temperature sensor of its pin at ECM connector which has bad contact or damaged wire along the way from ECM.

Well, the faults are Stored (Historic) and not Current. Have you cleared the faults since making repairs? Is the check engine light on? Is there any Freeze Frame info available?

That's the funny thing it was not check engine light on.
After changing the sensor we cleared the fault stored and now is back on with additional ECU aswell

WEIRD...


says who...?

-- What module reports com issue with the ECU??

-- This looks weird because we don't yet understand.


-- What else is unstable... or is it just ECU only and chassis's working normally??

-- Bad GND and low voltage can always ready to deliver transient chaos... better take care if the basics before replacing a collection of good modules
Temp sensor is built to be reliable with sealed metal sensor.


> ​​​​​​Scanner only tells one part of the story, what's known about this vehicle ???
