Code B19F5 RAM Description

The B19F5 diagnostic trouble code (DTC) indicates an open circuit condition in the Right Power Sliding Door Latch Control 2 circuit. This code is specific to vehicles equipped with power sliding doors, which are designed to enhance convenience and accessibility, particularly in minivans and some SUVs. The latch control circuit is responsible for communicating the status of the door latch to the vehicle’s Body Control Module (BCM). When the BCM detects an open circuit in this particular latch control, it triggers the B19F5 code.
