What does it mean
The B1404 code indicates a fault in the driver side airbag deployment control circuit. This can lead to improper deployment of the airbag in an accident.
Promptly addressing this code through professional assistance is crucial for maintaining the safety and effectiveness of the airbag system.
Neglecting maintenance can increase the risk of injuries in accidents.
what are the symptoms
The B1404 code indicates potential problems with the airbag system. Here are the symptoms to watch out for:
- Airbag Warning Light: The code triggers the airbag warning light on the dashboard, indicating an issue with the driver side airbag deployment circuit.
- RCM Analysis: The Restraint Control Module (RCM) checks the deployment loop resistance. If it's outside the desired range, the B1404 code is triggered.
- Intermittent Faults: Small changes in resistance can cause intermittent faults, resulting in the driver side airbag activating or deactivating sporadically.
- Proper Repair: It's important to follow the diagnosis process to fix the underlying issues and prevent the B1404 code from coming back.
Regular maintenance of the airbag system is crucial for occupant safety. By conducting routine inspections and promptly addressing any potential issues, the risk of encountering the B1404 code can be minimized.
What are the causes
The B1404 code can be caused by a faulty driver side airbag, a problem with the airbag harness, a poor electrical connection in the airbag circuit, a faulty Restraint Control Module (RCM), or other factors.
It is important to avoid misunderstandings about this code, as they can result in incorrect diagnosis and unnecessary repairs. Remember, this code specifically relates to the driver side airbag deployment control circuit.
To prevent the B1404 code from coming back, make sure to regularly inspect and maintain the driver side airbag system, check for proper electrical connections, and address any issues promptly. It is also helpful to follow the diagnostic process and use accurate diagnostic tools to identify and fix the underlying cause of the code.
What Tools are Needed to diagnose
To diagnose the B1404 code accurately, you need to consistently use diagnostic tools. Here are some ideas about the tools commonly used for troubleshooting the B1404 code:

- Oscilloscope: An oscilloscope analyzes the signal waveform in the airbag circuit, assisting in identifying any abnormalities.
- Are there any specialized tools required for diagnosing and repairing the B1404 code?
- Airbag diagnostic tool: Some vehicles may need a specialized airbag diagnostic tool to access and diagnose the airbag system.
- SRS simulator: A simulator can be used to test the airbag system without deploying the airbags, ensuring the technician's safety during diagnosis and repair.
How to fix Step by Step
Step 1: Use the appropriate tools to diagnose the B1404 code.
Step 2: Proceed with the necessary repairs to fix the issue with the driver-side airbag.
Step 3: Visually inspect the wiring harness and connectors for any damage.
Step 4: Look for any broken, bent, pushed out, or corroded connector pins.
Step 5: Check for damaged components and ensure that the PID value is within the desired range.
Step 6: If any faults are found during the inspection, follow the potential solutions listed in the previous subtopic.
Step 7: Address any open or shorted circuits, poor electrical connections, or faulty components.
Step 8: Troubleshoot and address these issues to resolve the B1404 code.
Step 9: Ensure the proper functioning of the driver-side airbag after the repairs are completed.
What are the Common Diagnosis Mistakes
What are some common mistakes that occur when diagnosing the B1404 code?
