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 for leaks in the braking system at the circuit level during braking events and also checks for leaks at the channel level during shutdown. This fault will set if the leakage circuit cannot be isolated successfully. This DTC can also set if the calipers were compressed in the event of a brake pad replacement or caliper removal for access to other brake and chassis component repairs.
