What is B016F?

The diagnostic trouble code B016F refers to a malfunction related to the rear passenger door harness and its communication with the vehicle’s Body Control Module (BCM). This code typically indicates that there is an issue with the wiring or connections in the rear passenger door, which can prevent the door from functioning correctly. In practical terms, if your vehicle registers this code, you might experience problems such as the rear door not locking or unlocking properly, issues with the window's operation, or even the electronic child lock feature failing to engage. Drivers may also notice that the interior lights associated with the rear door do not operate as expected. If left unaddressed, this can lead to further electrical issues, impacting the safety features related to the rear doors. It’s essential to diagnose and resolve the underlying issues causing B016F, as they can compromise vehicle security and passenger safety. Regular inspections of the door wiring, especially after harsh weather conditions or previous repairs, can help prevent this issue from occurring.

Symptoms

Common symptoms when B016F is present:

  • The check engine light is illuminated, specifically related to the rear passenger door functionality.
  • The rear door does not lock or unlock with the key fob or central locking system, causing inconvenience.
  • Windows in the rear passenger door may not operate properly, affecting passenger comfort.
  • Interior lights linked to the rear door fail to illuminate when the door is opened, indicating a wiring issue.
  • The electronic child lock feature might not engage, posing a potential safety risk for young passengers.

Possible Causes

Most common causes of B016F (ordered by frequency):

  1. The most common cause of the B016F code is damaged wiring within the rear passenger door harness, which occurs in approximately 60% of cases. This damage can stem from wear and tear or accidents.
  2. A second cause is poor connections at the door's electrical connectors, which may result from corrosion or loose terminals. This is often seen in older vehicles.
  3. Another potential cause is a malfunctioning Body Control Module (BCM) that fails to communicate properly with the door systems. Regular diagnostic checks can help prevent this.
  4. Less commonly, water intrusion into the door cavity can lead to electrical shorts or corrosion in connectors, creating intermittent issues.
  5. A rare but serious cause could be an aftermarket accessory installation that interferes with the door's electrical systems, leading to failure in communication.
