What is B0616?

DTC B0616 refers to a specific issue within the body control module (BCM) related to the driver's door switch circuit. When this code appears, it indicates that the BCM is unable to detect the status of the driver's door, which can lead to various malfunctions in vehicle features like power windows, locks, and interior lighting. The code often triggers when there's a fault in the door switch, wiring, or the BCM itself. For vehicle owners, this can mean that functions such as remote locking or unlocking may fail, and in some cases, it could prevent the vehicle from starting. It's essential to address this issue promptly as it can lead to further electrical problems or safety concerns. While DTC B0616 is not immediately critical for driving, neglecting it can cause more extensive electrical failures over time. It's not uncommon for this code to appear in models such as the 2006-2011 Ford Fusion, 2008-2010 Ford Escape, and various other Ford and Lincoln vehicles from around the same production years, making it a prevalent concern for many owners.

Symptoms

Common symptoms when B0616 is present:

  • The check engine light may illuminate, indicating a fault in the BCM.
  • Power window operations become erratic, including failure to open or close.
  • Interior lights may not turn on when the driver's door is opened, impacting visibility.
  • Remote locking and unlocking may completely fail, making access to the vehicle difficult.
  • In extreme cases, the vehicle may experience starting issues due to BCM malfunctions.

Possible Causes

Most common causes of B0616 (ordered by frequency):

  1. The most common cause of B0616 is a faulty door switch, with a likelihood of about 60%. This switch can wear out over time or suffer from corrosion.
  2. A damaged wiring harness or loose connections in the door can cause intermittent faults, accounting for around 25% of cases.
  3. BCM failures are less common but can occur, especially in older vehicles, contributing to about 10% of B0616 occurrences. Regular inspections of electrical systems can help prevent this.
  4. Moisture intrusion into the switch or connectors can lead to circuit failures, which while rare, can create significant issues if not addressed.
  5. In some instances, software glitches in the BCM may cause this code to appear, warranting a software update or reset.
