Modern vehicles are equipped with sophisticated onboard diagnostics systems that monitor various aspects of the vehicle’s performance. When an issue is detected, the system triggers the check engine light and stores a corresponding trouble code. One such code is B0016, which pertains to a problem in the driver frontal deployment loop stage 1.


RF/Passenger Frontal Deployment Loop (Single Stage or Stage 1) Resistance Low

Check engine code B0016 specifically relates to the driver frontal deployment loop stage 1. This code is stored when the system detects an issue in the circuit or components responsible for deploying the driver-side airbag in the event of a collision. The code indicates a potential problem in the deployment loop that might compromise the airbag’s functionality.

Symptoms of Check Engine Code B0016

When the B0016 code is triggered, you might experience certain symptoms that could indicate an issue with the driver frontal airbag deployment loop. These symptoms include:

  • Illuminated Airbag Light: The most common and noticeable symptom is the illumination of the airbag warning light on your dashboard.
  • Non-Functional Airbag: In some cases, the driver’s side airbag might not deploy as intended during an accident, posing a safety risk.

Causes of Check Engine Code B0016

Several factors can lead to the activation of the B0016 code. Some potential causes include:

  • Faulty Airbag Clock Spring: The clock spring is a component that allows electrical connections to pass through while the steering wheel is being turned. A faulty clock spring can disrupt the signal to the driver frontal airbag.
  • Wiring Issues: Damaged or corroded wiring within the deployment loop circuit can prevent proper communication and functionality of the airbag.
  • Airbag Module Problems: Malfunctions within the airbag control module can lead to incorrect deployment signals.

Diagnosing Check Engine Code B0016

If you suspect the B0016 code has been triggered in your vehicle, it’s crucial to diagnose the issue accurately. Here’s how you can approach the diagnosis:

  1. Scan for Trouble Codes: Use an OBD-II scanner to retrieve the trouble codes stored in your vehicle’s system, including the B0016 code.
  2. Inspect Wiring and Connections: Carefully examine the wiring and connections associated with the driver frontal airbag deployment circuit for any signs of damage or corrosion.
  3. Check Clock Spring: Test the clock spring’s functionality to ensure it’s transmitting the necessary signals.

Fixing Check Engine Code B0016

Once you’ve diagnosed the issue, it’s time to address it effectively:

  1. Replace Faulty Components: If you’ve identified a faulty clock spring, airbag module, or damaged wiring, replace these components with genuine parts.
  2. Clear Trouble Codes: After making the necessary repairs, use your OBD-II scanner to clear the trouble codes and reset the check engine light.
  3. Verify Repairs: Take your vehicle for a test drive to ensure that the airbag light remains off and the airbag deploys correctly during a test deployment.


Understanding the Definition of check engine code B0016 is essential for maintaining the safety and functionality of your vehicle’s airbag system. By recognizing the symptoms, causes, and steps to diagnose and repair the issue, you can ensure that your vehicle’s safety features are in optimal condition.
