Question

Quizplus · Accepted Answer

The VIN (Vehicle Identification Number) is actually a 17-digit number, not 19, making Technician A's statement incorrect. Technician B is correct; some vehicles do indeed have an inertial shut-off switch that turns the fuel pump off in the event of a collision to prevent fuel leaks and potential fires.
