ABSTRACT:
A trouble diagnosis device of a vehicle body acceleration sensor by determining that the output fixing trouble of the vehicle body acceleration sensor or the like is not generated at a point of time that the fluctuation width of the output value of a vehicle body acceleration sensor becomes a predetermined value or above during the traveling of the vehicle with the vehicle speed equal to or more than the predetermined speed, and by stopping the trouble diagnosis of the output fixing trouble of the vehicle body acceleration sensor or the like until the vehicle speed is lowered to a value less than the predetermined speed thereafter, it is possible to avoid the trouble diagnosis of the output fixing trouble of the vehicle body acceleration sensor or the like when that the trouble diagnosis of the output fixing trouble of the vehicle body acceleration sensor or the like is unnecessary.
