How to Diagnose and Solve B1928 Air Bag Safing Sensor Output Circuit Failure Issues

Introduction

Airbags are an essential safety feature in modern cars. They are designed to protect the driver and passengers in the event of a collision. However, if the airbag system is not functioning correctly, it can be dangerous. One of the most common issues with airbags is the B1928 airbag safing sensor output circuit failure. In this article, we will discuss how to diagnose and solve this issue.

What is the B1928 Airbag Safing Sensor Output Circuit Failure?

The B1928 code is a diagnostic trouble code (DTC) that indicates a problem with the airbag safing sensor output circuit. The safing sensor is responsible for detecting a collision and sending a signal to the airbag control module to deploy the airbags. If the safing sensor output circuit fails, the airbags may not deploy in the event of a collision.

Diagnosing the B1928 Airbag Safing Sensor Output Circuit Failure

To diagnose the B1928 code, you will need an OBD-II scanner. Follow these steps:

Step 1: Connect the OBD-II Scanner

Connect the OBD-II scanner to the diagnostic port under the dashboard.

Step 2: Read the Codes

Read the codes using the OBD-II scanner. If the B1928 code appears, it means there is a problem with the airbag safing sensor output circuit.

Step 3: Check the Wiring

Check the wiring between the airbag control module and the safing sensor. Look for any signs of damage or corrosion. If the wiring is damaged, repair or replace it.

Step 4: Check the Safing Sensor

Check the safing sensor for any signs of damage or corrosion. If the sensor is damaged, replace it.

Step 5: Clear the Codes

Clear the codes using the OBD-II scanner. If the B1928 code does not reappear, the issue has been resolved.

Solving the B1928 Airbag Safing Sensor Output Circuit Failure

If the issue persists after following the diagnostic steps, you may need to replace the airbag control module. This is a complex and potentially dangerous task that should only be performed by a qualified mechanic.

Conclusion

The B1928 airbag safing sensor output circuit failure is a serious issue that should be addressed immediately. If you suspect there is a problem with your airbag system, follow the diagnostic steps outlined in this article. If the issue persists, seek the help of a qualified mechanic.
