What is B0D35?
The diagnostic trouble code B0D35 typically relates to issues within the vehicle's body control module (BCM) or associated systems. This code is commonly encountered in vehicles like the 2015-2018 Honda Accord and Toyota Camry. When the B0D35 code is triggered, it indicates that there is a fault related to the interior lighting system or the door lock/unlock functions. In practical terms, this could manifest as malfunctioning lights inside the vehicle, doors that don’t lock or unlock properly, or even issues with the vehicle’s security system. The BCM plays a critical role in managing these functions, and when it detects an irregularity, it stores the B0D35 code in the system. The implications of ignoring this code can range from minor inconveniences, such as annoying flickering lights, to more serious safety concerns if the door locks fail to operate correctly. As a vehicle owner, understanding this code can help you take appropriate action before it leads to further complications or costly repairs.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0D35 is present:
- The interior lights flicker or fail to turn on when the doors are opened, which can be frustrating and inconvenient.
- The doors may not lock or unlock correctly, requiring manual intervention, which can be a safety hazard.
- You may notice the vehicle's alarm system acting erratically, such as triggering without cause or failing to activate.
- The battery could drain faster than normal due to electrical components not shutting off properly.
- In some cases, the vehicle may experience issues with remote key fob functionality, making it difficult to lock or unlock doors remotely.
Possible Causes
Most common causes of B0D35 (ordered by frequency):
- A faulty body control module (BCM) is the most common cause of the B0D35 code, with an estimated likelihood of 60%. This can occur due to wear and tear or electrical issues.
- Wiring issues such as damaged or corroded wires can lead to communication failures between the BCM and the vehicle's electrical systems, contributing to the B0D35 code.
- Bad ground connections affecting the BCM can also trigger this code, so ensuring all ground connections are solid is crucial for prevention.
- Less common causes may include software glitches in the BCM, which can sometimes be resolved with a software update.
- In rare cases, a short circuit in the interior lighting system or door lock actuators can cause the B0D35 to appear, usually requiring a more in-depth diagnostic approach.

Diagnostic Steps
Professional B0D35 Diagnosis Process
Follow these systematic steps to accurately diagnose B0D35. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Start with an initial visual inspection of the wiring and connectors related to the BCM
Step 1: Start with an initial visual inspection of the wiring and connectors related to the BCM. Look for any obvious signs of damage or corrosion that could affect connections (5-10 minutes).
Step 2: Step 2: Use the GeekOBD APP to perform an OBD2 scan, retrieving the B0D35 code along with any additional codes
Step 2: Use the GeekOBD APP to perform an OBD2 scan, retrieving the B0D35 code along with any additional codes. Make sure to check the freeze frame data for context (10-15 minutes).
Step 3: Step 3: Conduct component testing on the BCM and associated wiring using a multimeter to assess voltage and continuity, particularly at suspected faulty points (20-30 minutes)
Step 3: Conduct component testing on the BCM and associated wiring using a multimeter to assess voltage and continuity, particularly at suspected faulty points (20-30 minutes).
Step 4: Step 4: After addressing any found issues, perform a system function test to ensure all components are operating correctly
Step 4: After addressing any found issues, perform a system function test to ensure all components are operating correctly. Clear the codes and recheck (10-15 minutes).
