Other XC90 Problem: - XC90 D5 flick, the error message: 0A31

Mart1977 · Apr 17th, 2016, 21:39

My XC90 D5 136kW MY07 began to flick, sometimes intensely.
Got diagnostic device (Delphi) of the proposed and provide fault 0A31, I found a match: "Control module communication. Signal missing from the Engine Control Module (ECM)."
Browsing through various forums, I realized that there may be a case of bad wiring.
Can anyone advise where to get started, and what could check?

Br,

Mart.

What do you mean by 'flick' ? Headlights, interior lights flickering? Dash screen switching off?

Case closed:
fifth cylinder injector pins were tarnished

Hi,I have the same code too. My Volvo also occasionally losses power up hill.

How did you fix your code 0A31 fault?

Thanks

OP was last on line in 2017 so unlikely he will get back to you.

I would assume he cleaned the connections on the injector which he stated were tarnished

Cheers

Dave
