Code B3055 2016 GMC Sierra Description
The B3055 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates that there is either no transponder modulation or no transponder detected in the vehicle's system. A transponder is a small electronic device that sends out a signal to a receiver, allowing for secure communication between different components of the vehicle. In this case, the absence of proper transponder modulation or detection can lead to issues with the vehicle's security system, specifically the immobilizer function.
Common Causes of B3055 2016 GMC Sierra
- Faulty transponder key
- Malfunctioning transceiver module
- Wiring issues in the transponder system
- Communication errors between the transponder and receiver
- Faulty immobilizer control module
Symptoms of B3055 2016 GMC Sierra
- Intermittent starting issues
- Vehicle not starting at all
- Security light flashing on the dashboard
- Inability to engage the ignition system
How to Fix B3055 2016 GMC Sierra
- Check and replace the transponder key if necessary.
- Test the transceiver module and replace it if it is faulty.
- Inspect the wiring in the transponder system for any damage or corrosion, repairing or replacing as needed.
- Ensure proper communication between the transponder and receiver by reprogramming or replacing components if necessary.
- Test the immobilizer control module and replace if deemed faulty.
Cost to Fix B3055 2016 GMC Sierra
The typical repair costs for addressing a B3055 code in a 2016 GMC Sierra can range from $200 to $500, including parts and labor.

Frequently Asked Questions about B3055 2016 GMC Sierra Code
1. What does the OBDII code B3055 mean on a 2016 GMC Sierra?
The B3055 code indicates a "No Transponder Modulation" or "No Transponder" issue, meaning the vehicle's immobilizer system cannot detect or communicate with the transponder in the key.
2. What are common symptoms of the B3055 code in a GMC Sierra?
Common symptoms include the engine not starting, the security light staying illuminated or flashing, and the vehicle failing to recognize the key.
3. What causes the B3055 code to appear on a 2016 GMC Sierra?
Causes may include a faulty key transponder, a damaged ignition key, issues with the immobilizer antenna, a malfunctioning Body Control Module (BCM), or interference from other electronic devices.
4. Can a low key fob battery trigger the B3055 code?
Yes, a weak or dead key fob battery can prevent the transponder signal from being detected, potentially triggering the B3055 code.
5. How do you fix the B3055 code on a 2016 GMC Sierra?
Repairs may involve replacing the key fob battery, reprogramming the key, inspecting and repairing the immobilizer antenna, or diagnosing and replacing the BCM if necessary.
6. Can the B3055 code be caused by a damaged key?
Yes, a physically damaged or improperly programmed key can prevent the transponder signal from being transmitted, leading to the B3055 code.
7. How can you test if the key’s transponder is working on a 2016 GMC Sierra?
You can test the key by using a spare programmed key. If the spare key starts the vehicle, the issue is likely with the original key or its transponder.
8. Does the B3055 code require professional diagnosis?
While some basic checks (like replacing the key fob battery) can be done at home, a professional diagnostic tool is often needed to pinpoint the exact cause and reprogram the system if required.
9. Can interference from other electronics cause the B3055 code?
Yes, strong electronic signals or devices near the key or ignition can interfere with the transponder signal, potentially resulting in the B3055 code.
10. Is reprogramming the key always necessary to resolve the B3055 code?
Not always. Reprogramming is only needed if the key or immobilizer system has lost synchronization. Other fixes, like replacing a faulty component, may resolve the issue without reprogramming.
