When it comes to diagnosing a Dodge B0072-13 Code, there are certain rules to follow to make sure that the problem is identified and fixed correctly. This code indicates a Passenger Seatbelt Buckle Pretensioner Deployment Control Circuit Open, which is a problem with the Occupant Restraint Controller (ORC) sending a test current to the Squibs. The cause of this issue can be any of the following: (R54) Passenger Seatbelt Tensioner Line 2 Circuit Open, (R56) Passenger Seatbelt Tensioner Line 1 Circuit Open, Passenger Seatbelt Buckle Tensioner, or Occupant Restraint Controller (ORC). The failure type is Circuit Open, which is when a control module determines an open circuit due to lack of bias voltage, low current flow, or no change in the state of an input in response to an output.
Causes and Solutions of Dodge B0072-13 Code
| Cause | Solution |
|---|---|
| (R54) Passenger Seatbelt Tensioner Line 2 Circuit Open | Check the wiring of the seatbelt tensioner line and replace if necessary |
| (R56) Passenger Seatbelt Tensioner Line 1 Circuit Open | Check the wiring of the seatbelt tensioner line and replace if necessary |
| Passenger Seatbelt Buckle Tensioner | Replace the passenger seatbelt buckle tensioner for a new one |
| Occupant Restraint Controller (ORC) | Replace ORC with a new one |
R54 & R56 Passenger Seatbelt Tensioner Line
The R54 and R56 passenger seatbelt tensioner lines are responsible for providing the proper amount of tension to the seatbelt when it is pulled tight. If there is an open circuit in either of these lines, it will cause the Dodge B0072-13 Code to be thrown. To fix this issue, check the wiring of the seatbelt tensioner line and replace it with a new one if necessary.
Passenger Seatbelt Buckle Tensioner
The passenger seatbelt buckle tensioner is responsible for providing the necessary tension to the seatbelt when it is buckled up. If this tensioner is not functioning properly, it can cause the Dodge B0072-13 Code to be thrown. To fix this issue, replace the passenger seatbelt buckle tensioner for a new one.
Occupant Restraint Controller (ORC)
The Occupant Restraint Controller (ORC) is responsible for sending a test current to the Squibs which helps to detect any open circuits. If the ORC is not functioning properly, it can cause the Dodge B0072-13 Code to be thrown. To fix this issue, replace ORC with a new one.
Conclusion: Resolving the Dodge B0072-13 Code
When it comes to resolving the Dodge B0072-13 Code, there are a few different causes that need to be taken into consideration. The most common causes are (R54) Passenger Seatbelt Tensioner Line 2 Circuit Open, (R56) Passenger Seatbelt Tensioner Line 1 Circuit Open, Passenger Seatbelt Buckle Tensioner, and Occupant Restraint Controller (ORC). To fix these issues, it is recommended to check the wiring of the seatbelt tensioner lines and replace any necessary parts. Additionally, the passenger seatbelt buckle tensioner and ORC should also be replaced with a new one. By following these steps, you can successfully resolve the Dodge B0072-13 Code.
