What is B1130?
The diagnostic trouble code (DTC) B1130 indicates a malfunction within the Body Control Module (BCM), which is responsible for managing various electronic systems in your vehicle, including door locks, lighting, and interior features. This code is often seen in models like the 2015-2019 Honda Accord and the 2016-2020 Toyota Camry. When the BCM detects an issue, it triggers the check engine light, alerting you that something isn’t functioning correctly. Ignoring this code can lead to more significant electronic failures or even affect your vehicle’s safety systems. The BCM communicates with other control modules in the vehicle, and a fault here can cause various symptoms, impacting your driving experience. Regular diagnostics and timely repairs are crucial in preventing potential electrical issues that could escalate into costly repairs down the line.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B1130 is present:

- Power windows may fail to operate, leaving you unable to adjust them as needed.
- Interior lights flicker or do not respond to the door opening, affecting convenience and safety.
- The vehicle's alarm system may malfunction, either not activating or triggering without cause.
- Remote keyless entry may not work, making it difficult to unlock or lock your car.
Possible Causes
Most common causes of B1130 (ordered by frequency):
- The most common cause is a faulty Body Control Module, which accounts for about 60% of B1130 cases. This can happen due to moisture exposure or electrical shorts.
- Another common issue is damaged wiring or connectors leading to the BCM, which can occur from wear and tear or accidents.
- Corrosion in the BCM connectors can also lead to this code; regular inspections can help prevent this.
- Less commonly, software glitches within the BCM may cause this code to set, necessitating a software update or reprogramming.
- In rare cases, a malfunction in associated components like the ignition switch can trigger the B1130 code.
