When it comes to Chrysler vehicles, the Chrysler Code B212D is a troublesome diagnostic code that can cause a variety of issues. This code indicates that there is an ignition run only input circuit open. This code can be caused by a variety of issues, ranging from a faulty TIPM fuse to a faulty Occupant Restraint Controller (ORC). In order to identify and address the underlying cause of this code and get your vehicle running again, it is important to understand the symptoms, causes, and solutions for this issue.
Causes and Solutions for Chrysler Code B212D
| Cause | Solution |
|---|---|
| TIPM Fuse 27 Open | Replace the fuse and check for shorts in the circuit. |
| TIPM Fuse 27 Supply Voltage Low | Check the voltage in the circuit and diagnose the power supply issue. |
| (F100) Fused Ignition Switch Output (RUN) Circuit Open | Check the circuit for any breaks or shorts. |
| (F100) Fused Run Relay Output Circuit Short to Ground | Inspect the circuit and replace any damaged components. |
| Occupant Restraint Controller (ORC) | Diagnose the ORC and replace any faulty components. |
TIPM Fuse 27 Open
When the TIPM fuse 27 is open, it can cause the Chrysler Code B212D to be triggered. This means that the fuse has been disconnected or blown, resulting in an open circuit in the ignition run only input. The solution to this problem is to replace the fuse and check for any shorts in the circuit.
TIPM Fuse 27 Supply Voltage Low
Another common cause of the Chrysler Code B212D is a supply voltage issue. If the voltage in the circuit is too low, it can cause the code to be triggered. In this case, the solution is to check the voltage in the circuit and diagnose the power supply issue.
(F100) Fused Ignition Switch Output (RUN) Circuit Open
The (F100) Fused Ignition Switch Output (RUN) Circuit can also be responsible for triggering the Chrysler Code B212D. This means that there is an open circuit in the ignition run only input, which needs to be checked for any breaks or shorts.
(F100) Fused Run Relay Output Circuit Short to Ground
The (F100) Fused Run Relay Output Circuit can also cause the Chrysler Code B212D. In this case, the circuit has a short to ground, which needs to be inspected and any damaged components need to be replaced.
Occupant Restraint Controller (ORC)
Finally, the Occupant Restraint Controller (ORC) can be responsible for triggering the Chrysler Code B212D. In this case, the solution is to diagnose the ORC and replace any faulty components.
Conclusion
The Chrysler Code B212D is a troublesome diagnostic code that indicates an ignition run only input circuit open. There are several causes of this code, ranging from a faulty TIPM fuse to a faulty Occupant Restraint Controller (ORC). In order to identify and address the underlying cause of this code and get your vehicle running again, it is important to understand the symptoms, causes, and solutions for this issue. By following the above solutions for the Chrysler Code B212D, you can get your vehicle running smoothly again.
