2015 Volvo D13 ECU maintenance required

Did they find the problem? I'm getting this message after I have has to change the NOX sensor 2x

 

Having the same issue. What was the problem?

 

Main power switch was the problem for me. 2017 Volvo 780 with D13. Turn truck off and suddenly no power anywhere, would wiggle all the wires by battery and it’d start again with ECU Maintenance Required message on dash. Replaced the master power switch on top of batteries and haven’t had issue since.

 

It’s not my problems

I have different issue

Dealership contact me just now.
I will a post report today or tomorrow.
After 10 days) them think them know What is happening.

You only right about if same thing happened. First think you have to check switch and battery connection. Best. Clean them every 6 months. Very good cleaning. And it’s help you lot!!!!

 

I've been having the same code for several weeks now but I don't believe my truck is losing power and it's cranking ok.

 

The clicking on startup is the abs system testing itself. I assume you mean the clicks when you put the key to the run position and not start. Eitherway it will always do that. Second ECM maintenance is because updates were probably made to the ECM to protect the engine. Could also be many reasons, but your better off doing it. The longer you wait the worse the $$$ total will be in the end. Delaying could cause other problems down the road.
One guy wrote battery terminals. Doubtful.

 

How did you solve this issue?
