I think it relates to the ignition switch circuit. Have you disconnected the battery recently as this can give that error code if the vehicle was not asleep at the time. Could try the battery reset. Disconnect both battery terminal and short them together for a few seconds and then reconnect and see if the code returns.

Hi Globetrotter,

I might have disconnected the battery in the past year or so.
I tried to erase the error message with my Hawkeye. But it come back immediately.

I will do as PeteK suggests : leave it the way it is since it has no impact.

Thanks guys D3 TDV6 for holidays use,
