Can I drive my car with B017F or should I stop immediately?
While it's possible to drive with a B017F code, it is not recommended. Doing so could lead to further electrical issues or even a breakdown. It's best to have the issue diagnosed and repaired as soon as possible.
How can I diagnose B017F myself using GeekOBD APP?
Using the GeekOBD APP, you can perform an OBD2 scan to retrieve the B017F code and view freeze frame data. This will help you understand the conditions under which the code was triggered, allowing you to focus your diagnostic efforts on the battery and electrical system.
What vehicles are most commonly affected by B017F?
The B017F code is frequently seen in Chevrolet and GMC models from 2015 to 2020, such as the Chevrolet Silverado and GMC Sierra. It’s important to check for any recalls or technical service bulletins related to the BCM in these vehicles.
How can I prevent B017F from happening again?
Regular maintenance such as checking battery health, inspecting wiring and connections, and keeping the vehicle's software updated can help prevent the B017F code from occurring. Additionally, ensure that your electrical system is free from corrosion and moisture.
What is B017F?
The diagnostic trouble code (DTC) B017F indicates a problem with the Body Control Module (BCM) in certain Chevrolet and GMC vehicles, commonly seen in models from 2015 to 2020. This code is triggered when the BCM detects an issue with the battery voltage supply or the integrity of the battery management system. When this error occurs, it can lead to various electrical problems, including malfunctioning lights, issues with the vehicle's starting system, and other electronic malfunctions. Since the BCM manages multiple electronic systems, a B017F code can manifest in various ways, making it critical for vehicle owners to address it promptly. Neglecting this code can lead to further electrical issues, potentially leaving drivers stranded or causing additional damage to the vehicle’s electronic components. If you own a vehicle within this range, be particularly vigilant for this code, as it can indicate deeper electrical problems that may require professional diagnostics and repair.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B017F is present:
- The check engine light remains illuminated, signaling an underlying issue that requires attention.
- Unresponsive or malfunctioning electronic components, such as power windows or door locks, indicating a possible BCM failure.
- Fluctuations in electrical system behavior, like intermittent starting issues or dashboard lights malfunctioning.
- Decreased battery life or frequent battery failures, suggesting the BCM is not managing power correctly.
- Unexpected vehicle behaviors, such as automatic headlights not responding properly or alarm system issues.
Possible Causes
Most common causes of B017F (ordered by frequency):
- The most common cause of the B017F code is a weak or failing battery, occurring in approximately 40% of cases. A battery that is unable to maintain proper voltage can confuse the BCM and trigger this code.
- Another common cause is damaged wiring or poor connections within the electrical system. Corroded connectors or frayed wires can lead to inconsistent voltage readings, prompting the BCM to set a B017F code.
- Thirdly, software issues within the BCM can lead to erroneous code triggering. Keeping the vehicle's software updated can help prevent such issues.
- Less commonly, a defective BCM may be the root cause. This is a serious condition that often requires replacement, which can be expensive.
- Lastly, environmental factors like moisture intrusion can affect the BCM's performance, potentially leading to this DTC.

Diagnostic Steps
Professional B017F Diagnosis Process
Follow these systematic steps to accurately diagnose B017F. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Conduct an initial visual inspection of the battery and wiring
Step 1: Conduct an initial visual inspection of the battery and wiring. Look for signs of corrosion, loose connections, or physical damage (5-10 minutes).
Step 2: Step 2: Use the GeekOBD APP to perform an OBD2 scan
Step 2: Use the GeekOBD APP to perform an OBD2 scan. Retrieve all stored codes and freeze frame data to understand the context of the B017F code (10-15 minutes).
Step 3: Step 3: Test the vehicle’s battery voltage using a multimeter
Step 3: Test the vehicle’s battery voltage using a multimeter. Ensure the voltage is within the normal range (12.4 to 12.7 volts) with the engine off (15-20 minutes).
Step 4: Step 4: Inspect and test the wiring and connectors associated with the BCM for continuity and proper voltage (20-30 minutes)
Step 4: Inspect and test the wiring and connectors associated with the BCM for continuity and proper voltage (20-30 minutes).
Step 5: Step 5: If necessary, perform a software update on the BCM, and then clear the codes
Step 5: If necessary, perform a software update on the BCM, and then clear the codes. Recheck to see if the B017F code returns (10-15 minutes).
Step 6: Step 6: Conduct a road test under various conditions to ensure the vehicle operates normally without triggering the code again (15-20 minutes)
Step 6: Conduct a road test under various conditions to ensure the vehicle operates normally without triggering the code again (15-20 minutes).
