Common causes include a faulty battery energy control module, wiring issues, or a failing battery pack. Repair costs can vary, with module replacement ranging from $500 to $1,200 and wiring repairs typically costing between $100 and $300.

Can I drive my car with B0B35 or should I stop immediately?

It is advisable to stop driving if you see this code, as it can lead to further complications. Continuing to drive may cause additional damage to the battery or electrical systems, leading to more expensive repairs.

How can I diagnose B0B35 myself using GeekOBD APP?

Using the GeekOBD APP, you can perform a full system scan to retrieve the B0B35 code and other related codes. Check the freeze frame data for context, and perform visual inspections for wiring issues before considering more complex diagnostics.

What vehicles are most commonly affected by B0B35?

DTC B0B35 is often seen in models like the 2016-2020 Chevrolet Volt, as well as other hybrids and electric vehicles. If you own a vehicle from this category, stay vigilant for warning signs related to your battery system.

How can I prevent B0B35 from happening again?

Regular maintenance of your battery and electrical systems, including visual inspections and timely software updates, can help prevent issues. Additionally, avoid modifications that could interfere with the vehicle's electrical integrity.

What is B0B35?

DTC B0B35 is a diagnostic trouble code that generally indicates a problem within the vehicle's electrical system, specifically related to the battery energy control module (BECM). This code can often arise in hybrid and electric vehicles, such as the 2016-2020 Chevrolet Volt, where intricate battery management is crucial for optimal performance. When the BECM detects irregularities in voltage levels, current flow, or communication issues with the vehicle's electrical components, it triggers the B0B35 code. This can lead to significant operational problems including reduced battery efficiency, poor charging, and in severe cases, the vehicle may enter a limp mode to prevent further damage. As a vehicle owner, encountering this code means you should take it seriously, as it can affect your driving experience and the safety of your vehicle. Ignoring this code might lead to more extensive damage, costly repairs, and potentially leave you stranded. Therefore, understanding the implications of DTC B0B35 is essential for maintaining your vehicle's performance and reliability.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B0B35 is present:

Check engine light illuminated or flashing, indicating a fault that needs immediate attention.
Reduced battery performance, with noticeable loss in electric range and efficiency.
Vehicle may enter limp mode, limiting speed and power to protect the system.
Unusual battery charging patterns, where the battery may take longer to charge or not charge at all.
Increased frequency of battery-related warnings on the dashboard, indicating potential issues.

Possible Causes

Most common causes of B0B35 (ordered by frequency):

Faulty battery energy control module (BECM) - 60% likelihood. This is the most common cause of the B0B35 code due to component failure or software glitches.
Wiring issues or poor connections - 20% likelihood. Corroded or loose wiring can disrupt communication between the BECM and other systems.
Faulty battery pack - 10% likelihood. A failing battery pack may lead to inaccurate readings and trigger the B0B35 code.
Software issues - 5% likelihood. Outdated or corrupted software can cause miscommunication within the vehicle's electronic systems.
Less common but serious causes include external factors such as short circuits or aftermarket modifications that interfere with the vehicle's electrical system.

B0B35 Repair Costs

Cost Breakdown by Repair Type
