WARNING: This page is about a different car, the 2024 RAM ProMaster EV. However, it is still accessible from the selected car via links, so may be relevant.
The Brake System Control Module (BSCM) monitors each wheel speed sensor individually. A failure is detected, if the measured sensor voltage is continuously out of range, as compared to the thresholds of BSCM Wheel Speed Sensor (WSS) input values.
