Imagine having something draining the battery on a modern computer car.
The car has a master power distribution in the trunk. The car does not go to sleep for 2 hours after the car is locked. So to troubleshoot you need like 20 current reading VOM's and then be locked in the trunk for 2 hours waiting for the car to go to sleep to find the module that leaks too much current to stop the battery from going dead every night.
Yes that was done on a newer Mercedes.
How about the main computer board is not reading a sensor properly so it set the check engine light and the car can not pass inspection cause the light is lit for a non-emissions sensor problem. So a new computer is installed but does not work because it will not marry with the security computer. Off to dealer and $7000 and 2 new computers later to turn off the check engine light so it can pass inspection.
Then there is replacing the ignition key decoder computer to find the door switches no longer responded properly. You know head rest up makes seat go down. It was supposed to be the correct computer.
The new cars can parallel park themselves. This means they control the throttle, steering, transmission and brakes. What could possibly go wrong?
The first production drive by wire car is being brought on to the market- do you feel safer?
