What is B0696?

The diagnostic trouble code (DTC) B0696 indicates a problem with the vehicle's body control module (BCM). This code often points to an issue with the communication between the BCM and other systems, such as the power door locks, mirrors, or lighting systems. When the BCM detects a malfunction in one of these components, it triggers the B0696 code. This can lead to various electrical issues, including failure of door locks to operate, malfunctioning interior lights, or even problems with starting the vehicle. For owners of Ford, Lincoln, and Mercury models, particularly those from the early 2000s to the present, this code is essential to address. Ignoring B0696 can result in further electrical malfunctions, leading to more expensive repairs down the line. If your vehicle is experiencing symptoms associated with this code, it’s crucial to have it diagnosed and repaired by a qualified technician to ensure vehicle reliability and safety.

Symptoms

Common symptoms when B0696 is present:

  • Check engine light stays on constantly, indicating an underlying electrical issue that needs to be addressed.
  • Door locks may not respond when using the key fob or interior switch, causing inconvenience and security concerns.
  • Interior lights may flicker or fail to operate correctly, affecting visibility and comfort.
  • Dashboard warning lights may illuminate unexpectedly, signaling potential problems with other vehicle systems.
  • Intermittent starting issues can occur if the BCM fails to communicate properly with the ignition system.

Possible Causes

Most common causes of B0696 (ordered by frequency):

  1. The most common cause of B0696 is a faulty body control module, with a likelihood of around 60%. This can happen due to wear and tear or electrical shorts.
  2. Another common issue might be damaged wiring or connectors, which can account for approximately 25% of cases. This often results from corrosion or physical damage.
  3. A blown fuse related to the BCM can lead to this code as well, making up about 10%. Regular checks of the fuse box can help prevent this.
  4. Less common but serious causes include software issues within the BCM, which can lead to erratic behavior of vehicle systems.
  5. A rare but possible cause is interference from aftermarket electronic accessories, which can disrupt the BCM's normal functions.
