What is B0875?

DTC B0875 is a diagnostic trouble code that indicates a potential issue with the driver door module (DDM) or its communication with the vehicle’s body control module (BCM). This code often appears in vehicles like the 2015-2018 Honda Accord and Toyota Camry, where it can cause various electrical malfunctions. The DDM is responsible for controlling several features such as power windows, door locks, and mirrors. When the DDM fails or has a communication issue, it can lead to symptoms like non-functioning power windows or unresponsive door locks. This code could also potentially affect the vehicle's security features or cause the interior lights to malfunction. Ignoring DTC B0875 can lead to more severe electrical issues over time, so addressing it promptly is essential. Drivers may notice that their vehicle's electrical systems do not operate as expected, impacting convenience and safety. It’s crucial to understand that while the code itself does not indicate an immediate threat to safety, the resulting malfunctions might create inconvenient and unsafe conditions, prompting a timely diagnosis and repair.

Symptoms

Common symptoms when B0875 is present:

  • The check engine light and/or other warning lights may stay illuminated, signaling an issue with the electrical system.
  • Power windows may become inoperative, leaving the driver unable to open or close them, which can be inconvenient and unsafe.
  • Door locks might fail to respond, leading to difficulty in securing the vehicle, which poses a security risk.
  • Interior lights may malfunction, either staying on or failing to turn on when the doors are opened.
  • The vehicle's keyless entry system may become unresponsive, complicating access to the vehicle.

Possible Causes

Most common causes of B0875 (ordered by frequency):

  1. The most common cause of DTC B0875 is a faulty driver door module, which occurs in approximately 60% of cases. This could be due to wear or water damage.
  2. A second common cause is damaged wiring or connectors leading to the DDM, which can occur from corrosion or physical wear and tear.
  3. Thirdly, a software glitch in the vehicle's body control module can lead to improper communication with the DDM, which can often be resolved with a software update.
  4. Less common but serious causes include a failing body control module itself, which may require replacement if diagnosed.
  5. In rare cases, issues with related components, such as the ignition switch, may indirectly affect DTC B0875 by disrupting power supply to the DDM.
