What is B1570?
The B1570 diagnostic trouble code (DTC) indicates a problem with the Body Control Module (BCM) in your vehicle. This code is particularly common in various Honda and Acura models manufactured between 2005 and 2018. The BCM is responsible for controlling multiple functions in your vehicle, including lighting, door locks, and the alarm system. When the BCM detects a fault, it triggers the B1570 code, signifying that there is an issue with the module's communication or functionality. Drivers may notice symptoms such as the interior lights behaving erratically or the key fob not functioning properly. Ignoring this code can lead to further electrical issues, making it crucial to address it promptly. A malfunctioning BCM can also affect the vehicle's safety features, which could compromise overall safety while driving. Furthermore, if you plan to sell or trade in your vehicle, having a B1570 code can reduce its resale value, as potential buyers may view it as a sign of deeper electrical issues. Therefore, understanding the implications of the B1570 code and taking appropriate action is essential for maintaining your vehicle's performance and reliability.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B1570 is present:
- Check engine light remains illuminated, indicating an underlying issue.

Possible Causes
Most common causes of B1570 (ordered by frequency):
- The most common cause of the B1570 code is a faulty Body Control Module, with an estimated likelihood of 60%. This can occur due to wear and tear, electrical shorts, or exposure to moisture.
- A second common cause is damaged wiring or connectors related to the BCM. Corrosion or physical damage can lead to poor connectivity, causing the code to trigger.
- Another potential cause is issues with the vehicle's battery or charging system. Low voltage can affect the BCM's performance, so ensure your battery is in good condition.
- Less common but serious causes include a faulty ignition switch, which can lead to intermittent BCM operation. This issue should be addressed immediately.
- Rarely, software issues within the BCM itself can trigger this code, requiring an update or reprogramming to resolve.
