How to Diagnose and Solve B1935 Air Bag Passenger Inflator Circuit Resistance Low on Squib Issues

Introduction

Airbags are an essential safety feature in modern cars. They are designed to protect passengers in the event of a collision. However, airbag systems can sometimes malfunction, leading to error codes such as B1935. This error code indicates that there is a problem with the passenger airbag inflator circuit resistance, specifically that it is too low on the squib. In this article, we will discuss how to diagnose and solve B1935 airbag passenger inflator circuit resistance low on squib issues.

What is B1935 Error Code?

B1935 is an error code that indicates a problem with the passenger airbag inflator circuit resistance. The squib is a component of the airbag system that ignites the inflator to deploy the airbag. When the resistance of the circuit is too low, it can cause the airbag to deploy unexpectedly or not deploy at all in the event of a collision. This can be a serious safety issue, and it is important to diagnose and solve the problem as soon as possible.

Diagnosing B1935 Error Code

The first step in diagnosing B1935 error code is to use an OBD-II scanner to read the code. This will give you an indication of where the problem is located. However, it is important to note that the code alone does not provide enough information to diagnose the problem accurately. You will need to perform further tests to determine the root cause of the issue.

The next step is to check the wiring and connectors in the airbag system. Look for any signs of damage or corrosion. Check the resistance of the circuit using a multimeter. If the resistance is too low, it may indicate a problem with the squib or the wiring.

Solving B1935 Error Code

If the problem is with the wiring or connectors, you may be able to solve the issue by repairing or replacing the damaged components. However, if the problem is with the squib, you will need to replace it. This is a job that should only be performed by a qualified technician, as it involves working with the airbag system, which can be dangerous if not handled properly.

Preventing B1935 Error Code

To prevent B1935 error code from occurring, it is important to perform regular maintenance on your car’s airbag system. This includes checking the wiring and connectors for damage or corrosion, and replacing any damaged components. It is also important to follow the manufacturer’s recommended maintenance schedule for your car.

Conclusion

B1935 error code can be a serious safety issue, as it indicates a problem with the passenger airbag inflator circuit resistance. If you encounter this error code, it is important to diagnose and solve the problem as soon as possible. This involves checking the wiring and connectors, testing the resistance of the circuit, and replacing any damaged components. Regular maintenance of your car’s airbag system can help prevent this issue from occurring.
