A module failed ...imagine that? When you intentionally make a mechanical device no longer mechanical and rely strictly on electronics as opposed to vacuum of heat induced you end up with the vehicles we have NEW nowadays....something that bricks and their is nothing you can do to edge it home or off the way to get service. When they started to put computers in cars I was against it . As time goes by points/condensor’s and generators (as opposed to alternators)look pretty good.
KISS rule is long forgotten obviously.
It’s worse on big trucks.
My work truck is a ‘21 Kenworth, and the DEF sensor went bad. The check engine light came on followed a second later by the red stop engine light and buzzer. I barely had enough momentum to get over onto the shoulder of the road.
Then there is all the other fed mandated crap on there that reduces power and reliability.
My company doesn’t help things by governing the truck to 64mph, the nanny cam and GPS that was brutally hack jobbed into the electrical system that now causes random no start issues.
