The B0D59 code is commonly found in models like the 2015-2019 Jeep Cherokee and Dodge Durango, particularly regarding their body control systems.
How can I prevent B0D59 from happening again?
Regularly inspect wiring and connectors for wear, ensure software updates are applied, and maintain your vehicle's electrical system to reduce the risk of recurrence.
What is B0D59?
The diagnostic trouble code (DTC) B0D59 is a manufacturer-specific code primarily associated with the body control module (BCM) in certain vehicles, particularly in models from Jeep, like the Cherokee (2015-2019) and Dodge Durango (2015-2019). This code indicates a communication failure within the vehicle's electrical system, often relating to issues with the power liftgate module or other body-related controls. The BCM plays a crucial role in managing various electrical components such as lighting, windows, and locks. When the B0D59 code is triggered, it typically signifies that the BCM is unable to communicate with one of its connected modules. This can lead to a range of symptoms, including power liftgate malfunctions or inoperative electrical features, which could compromise the vehicle's usability and safety. Ignoring this code can lead to further electrical problems and potentially higher repair costs down the line, as related components may become damaged or fail completely. Addressing the issue promptly not only restores functionality but also ensures that all vehicle systems operate efficiently, enhancing your driving experience and safety.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0D59 is present:
- The Check Engine Light may illuminate, indicating an electrical issue that requires immediate attention.
- The power liftgate may become inoperative or fail to respond, leading to frustration when accessing the trunk.
- Electrical features such as windows and locks may intermittently work or fail completely, impacting vehicle usability.
- Unusual electrical behavior, such as flickering lights or malfunctioning dashboard indicators, may be observed.
- Diminished fuel efficiency may occur due to the BCM trying to compensate for the communication issues.
Possible Causes
Most common causes of B0D59 (ordered by frequency):
- The most common cause of B0D59 is a defective body control module, with a likelihood of around 60%. This could be due to internal faults or software issues.
- A second potential cause is wiring problems, such as frayed or corroded connections, which can disrupt communication between modules (30% likelihood).
- Faulty sensors or relays related to body functions may also trigger this code, making up about 10% of cases. Regular inspections can help prevent these issues.
- Less common but serious causes include short circuits in the electrical system that can lead to widespread electrical failures.
- A rare cause could be a completely failed battery affecting module communication, which is unlikely but possible, especially in older vehicles.
