Code B0013:04 Description
The B0013:04 diagnostic code indicates that there is an issue with the Driver Steering Wheel Air Bag Deployment Loop Stage 2 being open. This means that there is an open circuit in the deployment loop of the driver's steering wheel airbag system, preventing the airbag from deploying properly in the event of a crash. The deployment loop is a crucial component of the airbag system that ensures the airbag can deploy quickly and effectively to protect the driver in a collision.
Common Causes of B0013:04
- Damaged wiring: Wear and tear, corrosion, or physical damage to the wiring in the deployment loop can cause an open circuit and trigger this code.
- Faulty connectors: Loose or corroded connectors in the airbag system can prevent the proper flow of electricity and lead to an open circuit.
- Malfunctioning sensor: A sensor that is not detecting a crash accurately or is sending incorrect signals to the airbag system can cause the deployment loop to remain open.
- Impact damage: A previous collision or impact to the vehicle could have damaged the deployment loop components, leading to an open circuit.
Symptoms of B0013:04
- Airbag warning light on the dashboard: One of the most common symptoms of this issue is the illumination of the airbag warning light on the dashboard. This light indicates a problem with the airbag system and should not be ignored.
- Non-deployment of the driver's airbag: In the event of a crash, the driver's airbag may fail to deploy or may deploy improperly due to the open circuit in the deployment loop.
- Intermittent airbag deployment: The driver's airbag may deploy intermittently or unpredictably, posing a risk to the driver's safety.
- Safety system malfunction: The vehicle's safety systems may not function correctly, leading to potential safety hazards in the event of a collision.
How to Fix B0013:04
- Diagnose the issue: Use a diagnostic scanner to read the fault codes and determine the exact cause of the open circuit in the deployment loop.
- Inspect wiring and connectors: Check the wiring and connectors in the airbag system for any signs of damage, wear, or corrosion. Repair or replace any faulty components.
- Test sensors: Test the sensors in the deployment loop to ensure they are functioning correctly and sending accurate signals to the airbag system.
- Reset the airbag system: Clear the fault codes and reset the airbag system to see if the issue is resolved. If the code returns, further diagnosis may be necessary.
- Conduct a final test: Test the airbag system to ensure the driver's airbag deploys properly and the code does not reappear.
Cost to Fix B0013:04
The typical repair costs for resolving a B0013:04 code can range from $200 to $500, depending on the extent of the damage and the specific components that need to be repaired or replaced. This estimate includes the cost of parts and labor. However, it's important to note that the actual cost can vary based on factors such as the vehicle make and model, the location of the repair shop, and the severity of the issue. Additional diagnostic time and labor rates may also impact the total cost of the repair. It's recommended to consult with a qualified mechanic or repair shop to obtain a more accurate estimate for addressing this issue.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
