- With an interruption on pin B7, connection points A9 and E4 inside the ECU will have a low voltage, causing
brake pedal position sensor 2 to give no output signal, for instance. If the measurement is performed at B7, it will
also turn out that B7 in this situation will be internally connected to earth in the ECU Interrupted earth connection or
contact resistance in the earth connection of the rear axle modulator (D879)
