Code B196A RAM Description

The B196A diagnostic trouble code (DTC) indicates an overcurrent condition in the power liftgate's close direction circuit. This code is primarily associated with vehicles equipped with power liftgate systems, which allow the rear hatch or trunk to open and close automatically. When the vehicle's onboard diagnostic system detects that the current flowing through the liftgate motor exceeds the manufacturer's specified threshold during the closing operation, it triggers the B196A code.
