Code P00FF 2016 GMC Sierra Description
The P00FF diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates that the Body Control Module (BCM) has requested the Malfunction Indicator Lamp (MIL) to illuminate. The BCM is a crucial component of the vehicle's electrical system, responsible for controlling various functions such as lighting, door locks, and security features. When the BCM detects a fault that could potentially affect the vehicle's emissions or performance, it sends a signal to the Engine Control Module (ECM) to turn on the MIL.
Common Causes of P00FF 2016 GMC Sierra
- Faulty Body Control Module (BCM)
- Wiring issues or shorts in the electrical system
- Sensor malfunction
- Communication errors between control modules
- Software glitches or programming errors
Symptoms of P00FF 2016 GMC Sierra
- Illumination of the Malfunction Indicator Lamp (MIL) on the dashboard
- Issues with door locks or lighting functions
- Erratic behavior of security features
- Communication errors with other control modules
How to Fix P00FF 2016 GMC Sierra
- Perform a thorough diagnostic scan using a professional scan tool to retrieve the specific fault codes and pinpoint the issue within the BCM or related systems.
- Inspect the wiring harness for any damage, corrosion, or loose connections. Repair or replace as needed.
- Test the sensors and communication lines to ensure proper functionality. Replace any faulty components.
- If the issue lies within the BCM, it may need to be reprogrammed or replaced with a new unit.
- Clear the DTCs from the system and perform a final test drive to verify that the issue has been resolved.
Cost to Fix P00FF 2016 GMC Sierra
The cost of repairing a P00FF code on a 2016 GMC Sierra can vary depending on the specific cause of the issue and the labor rates in your area. On average, you can expect to pay anywhere from $200 to $500 for parts and labor. Keep in mind that diagnostic time and labor rates can fluctuate, so it's advisable to contact local auto repair shops for a more accurate estimate based on your location and vehicle specifics.

Frequently Asked Questions about P00FF 2016 GMC Sierra Code
1. What does the OBD-II code P00FF mean on a 2016 GMC Sierra?
P00FF indicates that the Body Control Module (BCM) has requested the Malfunction Indicator Lamp (MIL) to illuminate, typically due to an underlying issue detected by the BCM.
2. What are the common symptoms of P00FF on a 2016 GMC Sierra?
The most common symptoms include the check engine light turning on, possible warning messages on the dashboard, and erratic behaviors in electrical components such as lights, locks, or wipers.
3. What causes the P00FF code to appear on a 2016 GMC Sierra?
This code is often triggered by faults in the Body Control Module itself, communication issues between the BCM and other modules, or wiring/connectivity problems.
4. Can a faulty Body Control Module cause the P00FF code?
Yes, a malfunctioning BCM can send incorrect requests to illuminate the MIL, leading to the P00FF code being stored.
5. How can I diagnose the P00FF code on my 2016 GMC Sierra?
Start by using a scan tool to check for additional codes stored in the BCM or other modules. Next, inspect the wiring and connectors related to the BCM for damage or corrosion.
6. Is a P00FF code serious on a 2016 GMC Sierra?
It depends on the underlying issue. While the BCM’s request for MIL illumination might not directly affect drivability, the root cause should be diagnosed and repaired promptly to avoid further electrical issues.
7. Can I clear the P00FF code without repairing the problem?
Clearing the code without addressing the cause may result in the MIL turning back on, as the BCM will likely detect the issue again.
8. How much does it cost to fix a P00FF code on a 2016 GMC Sierra?
Repair costs vary widely depending on the issue. Wiring fixes might cost $100–$300, while BCM replacement can range from $500 to $1,200, including parts and labor.
9. Can a dead battery trigger the P00FF code on a 2016 GMC Sierra?
Yes, a weak or dead battery can cause communication errors between modules, potentially triggering the P00FF code.
10. Should I replace the Body Control Module to fix the P00FF code?
Replacing the BCM should only be done after thorough diagnostics confirm it as the root cause. Often, the issue can be resolved by repairing wiring or reprogramming the module.

On your 2016 GMC Sierra, the code P00FF with “MIL activate” means the Body Control Module (BCM) has requested the Malfunction Indicator Lamp (Check Engine Light) to turn on.
This code by itself doesn’t point to the exact problem — it’s more of a “message” from the BCM telling the ECM to light the MIL. You’ll need to check for any other stored codes in the BCM, ECM, or transmission modules to see what triggered it.
In most cases:
- Clear the code and see if it comes back.
- If it does, scan all modules (not just the engine) — the BCM may be flagging something like a communication error, emissions-related fault, or electrical issue.
So “MIL activate” just means the BCM told the system to switch on the check engine light, but the real cause is in the underlying codes.
