If you put the key in the ignition, hold mode and set on your trip computor then turn your key or start the car another function comes up, (digital speedo, and fuel used, if you press mode again it goes to system voltage and litres left in tank. use this to see system voltage. As for a fix you could try cleaning the battery terminals, clean earth points on engine/chassis, get the battery load tested, replace the regulator in the alternator, or it could be the alternator itself. No idea on the 68 code. Let us know how you go.
