MSV70 Simultaneous Operation Of Accelerator/Brake Pedals: Notes

This test module serves to detect whether the accelerator pedal mechanically jams or is otherwise difficult to move. This is determined by simultaneously operating the accelerator and brake pedals while the vehicle is being driven. The fault is set in the engine management system if a driver's demand is detected via the accelerator pedal for at least 1.5 seconds and in relation to this there is a brake signal. Here, the brake pressure is used as a measured variable. This prevents braking deceleration being stopped by a jamming accelerator pedal.
