This case involves a vehicle accident that occurred in a parking garage located in Wyoming. The vehicle reportedly went out of control and collided with a parking garage column and another vehicle. In the incident report, the driver stated he was driving the car when the brakes failed. At the time of inspection, the brakes were found to be functional (contrary to the driver’s statement) although the brake transmission shift interlock (BTSI) was not functioning properly. It appeared to be pinned against the floorboard at the time of the inspection. The data from the airbag control module (ACM) indicated the accelerator pedal was fully depressed prior to the collision with the parking garage column. The data from the ACM indicated that the brake pedal was not depressed at any time after engine start and prior to the collision. It also indicated that the transmission was shifted from Park to Drive while the accelerator pedal was fully depressed and the brake pedal was not depressed. This should not have been possible due to the vehicle’s brake transmission shift interlock (BTSI).
