Digi tacho fault code

Got an “Internal fault code 10” message today.
I checked this thread trucknetuk.com/phpBB2/viewtopic. … code+codes & code 10 reads "Vehicle Unit related security breach attempt events;
10 No further details

Pretty helpful really.

Anyone have any idea what this might be? First time I have driven this truck & the printout shows everything correctly. It’s the security breach thing thats worrying.

ive had the head unit pack in,when the new one was put in it came up with security breach every couple of hrs, so went back to main dealer,who then cleared all the fault codes and told the truck to " talk " to the digi.

has’nt come up since.

im sure at my previous job that when the tacho anylasis sheets came back they were comming up with security breach .
boss had panic attack , dragged me and my mate in office as he thought we were up to no good, we wernt.
when they checked into it it was found out on the pdi for the truck the fitter had taken the unit out to have a look at it which was then being recorded as a security breach.
