What is B02DA?
The B02DA diagnostic trouble code (DTC) indicates a problem with the left rear door latch or its associated circuitry in specific vehicles, notably 2015-2019 Dodge Ram trucks and Jeep models such as the Cherokee and Grand Cherokee. This code is triggered when the vehicle's onboard diagnostics system detects a fault in the door latch mechanism or its connection to the body control module (BCM). The door latch may not be functioning correctly, which can lead to the door not closing properly or remaining ajar while driving. This could pose a security risk and may also result in the door not unlocking or locking as intended. Additionally, if the latch is malfunctioning, it can affect the vehicle's electrical systems, leading to other issues, such as problems with interior lights or power windows. It's crucial for car owners to address this code promptly to ensure both the safety and functionality of their vehicle. Ignoring the B02DA code could lead to further complications down the line, making it imperative to diagnose and repair the underlying issue as soon as possible.
