The SRSCM
The SRSCM (System Reset and Security Control Module) is a critical component in Hyundai vehicles, and is responsible for managing the vehicle’s security system. When the SRSCM fails, it can cause the Enable Conditions Ignition to be “ON” and cannot be erased. This is one of the primary causes of Hyundai Code B1620, and it can be solved by replacing or repairing the SRSCM.
Deployment of DAB, PAB, SAB, and CAB
Another common cause of Hyundai Code B1620 is the deployment of the DAB, PAB, SAB, and CAB (Driver Airbag, Passenger Airbag, Side Airbag, and Curtain Airbag). When any of these airbags deploys due to an accident, it can cause the Enable Conditions Ignition to be “ON” and cannot be erased. To fix this, you must replace or repair the faulty part.
Enable Conditions Ignition “ON”
The Enable Conditions Ignition “ON” is another cause of Hyundai Code B1620. This can be solved by resetting the ECU. However, if the fault persists, then it could be a sign of a deeper underlying issue, and you should take your vehicle to a certified Hyundai mechanic for further inspection.
Diagnostic Time Qualification
The Diagnostic Time Qualification is the process of verifying that the fault is actually present in the vehicle. To do this, you must perform a diagnostic scan. This process will help you determine the cause of the fault and will allow you to take the necessary steps to rectify it.
