Stoneridge secondary sensor fault

Tacho read “secondary sensor fault” when i fired up this morning before i even put me card in. Clicked ok and cleared it card gone in as normal with no further fault codes…

Any ideas?

Probably just a glitch in the CAN signal from the vehicle to the tacho head. As long as it doesn’t keep appearing I wouldn’t worry about it.

This comes up virtually every visit to dealer, something to do with the software updates Scania carry out. No biggy.
