What is B1380?
The diagnostic trouble code (DTC) B1380 indicates a malfunction in the Body Control Module (BCM), which is crucial for managing various electrical systems in your vehicle. This code is commonly found in models like the 2010-2015 Honda Accord and the 2009-2013 Toyota Camry. The BCM controls functions such as power windows, interior lights, door locks, and even the vehicle's security system. When the BCM fails or experiences communication problems, it may trigger the B1380 code, leading to issues such as non-functional electrical components or intermittent problems. For car owners, this means you might notice that certain features like your power locks or interior lights are not functioning correctly. Ignoring this code can lead to further complications, as the BCM is integral to many of the vehicle's operations. To address B1380, you typically need to diagnose the underlying issue, which may involve checking the wiring, connectors, and the BCM itself, and possibly replacing it if necessary. Repairs can vary in complexity and cost, depending on the specific symptoms and the vehicle model.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B1380 is present:
- The check engine light remains illuminated, indicating an underlying issue with the BCM.
- Power windows may operate inconsistently or not at all, leading to frustration for drivers.
- Interior lights flicker or fail to turn on, affecting visibility inside the vehicle.
- The central locking system may not function correctly, posing a security risk.
- Other electrical accessories such as the radio or dashboard lights may show erratic behavior.
Possible Causes
Most common causes of B1380 (ordered by frequency):
- The most common cause is a failed Body Control Module, which occurs in about 60% of cases. This can be due to wear and tear or electrical shorts.
- Loose or corroded wiring connections to the BCM are the second most common cause, often leading to communication errors with the module.
- Faulty sensors can also trigger this code, as the BCM relies on various inputs to function correctly. Regular inspections can help catch these issues early.
- Less common but serious causes include water intrusion into the BCM, which can occur in vehicles exposed to heavy rain or flooding.
- Rarely, software issues in the BCM might require programming or updates from the dealership.

Diagnostic Steps
Professional B1380 Diagnosis Process
Follow these systematic steps to accurately diagnose B1380. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Conduct an initial visual inspection, checking for damaged wiring, loose connections, or corrosion that could affect the BCM (5-10 minutes)
Step 2: Use the GeekOBD APP to perform an OBD2 scan, retrieving all codes and freeze frame data to understand the context of the fault (10-15 minutes)
Step 3: Test suspected components with a multimeter or appropriate diagnostic tools to confirm their functionality (20-30 minutes)
Step 4: After making repairs, conduct a system function test to verify the BCM operates correctly and clear the codes (10-15 minutes)
Step 5: Perform a road test under various conditions to ensure the repair was successful and that the B1380 code does not reappear (15-20 minutes)
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
