The most common cause of B0C6E is a faulty ambient light sensor, which typically costs between $150 and $300 to replace. Wiring issues or BCM problems can also cause this code, with repair options ranging from $100 to $400.

Can I drive my car with B0C6E or should I stop immediately?

While it's not an emergency, it is advisable to address B0C6E promptly to ensure your vehicle's lighting operates correctly, especially when driving at night or in low-light conditions.

How can I diagnose B0C6E myself using GeekOBD APP?

To diagnose B0C6E with the GeekOBD APP, start by connecting the app to your vehicle's OBD2 port. Use the app to scan for codes, including B0C6E, and review freeze frame data to understand the conditions under which the code was triggered.

What vehicles are most commonly affected by B0C6E?

B0C6E is frequently found in vehicles like the 2016 Chevrolet Silverado and 2017 GMC Sierra. Other models from the Chevrolet and GMC lineup may also experience this issue, particularly those manufactured around the same years.

How can I prevent B0C6E from happening again?

To prevent B0C6E, regularly inspect the ambient light sensor and wiring for damage, keep the sensor clean and free from debris, and ensure any software updates for the vehicle's BCM are applied promptly.

What is B0C6E?

The B0C6E diagnostic trouble code indicates a malfunction within the vehicle's body control module (BCM) related to the ambient light sensor. This sensor is responsible for detecting light levels and adjusting vehicle lighting accordingly, such as headlights and interior lights. When the BCM receives incorrect information from this sensor, it triggers the B0C6E code. The implications of this code can lead to improper lighting functionality, which may compromise visibility and safety while driving. Drivers might notice that their headlights fail to automatically adjust to changing light conditions, or notice flickering lights, which may distract other drivers. This code is typically found in vehicles like the 2016 Chevrolet Silverado and 2017 GMC Sierra, among others. Addressing this issue is crucial as it directly affects your vehicle’s visibility at night or during low light conditions. Ignoring a B0C6E code can lead to further issues, such as battery drain due to lights remaining on or malfunctioning. If you see this code, it’s important to diagnose the problem promptly to ensure safe driving conditions.

Symptoms

Common symptoms when B0C6E is present:

  • Check engine light or dashboard warning light illuminates, indicating a malfunctioning sensor.
  • Headlights do not adjust automatically in response to ambient light changes, leading to potential visibility issues.
  • Interior lights may flicker or fail to illuminate properly, affecting driver and passenger comfort.
  • Battery may drain faster due to lights staying on when they should switch off.
  • Possible decreased functionality of other electronic systems due to BCM issues.

Possible Causes

Most common causes of B0C6E (ordered by frequency):

  1. The most common cause is a faulty ambient light sensor, accounting for about 60% of B0C6E cases. This sensor can become damaged due to exposure to moisture or debris.
  2. A second common cause is wiring issues, such as damaged or corroded wires leading to the BCM, which can result in intermittent signals.
  3. Another cause could be a malfunctioning BCM itself, which may require reprogramming or replacement.
  4. Less common but serious causes include software glitches in the vehicle's system, which may necessitate a firmware update.
  5. A rare cause could be a short circuit within the sensor circuit, which may require extensive diagnostics to locate.
