U0454 indicates the vehicle's communication network has received invalid or implausible data from the right side restraints control module, which manages side airbags and seat belt pretensioners on the right side of the vehicle. The code sets when the module's transmitted data fails plausibility checks, suggesting an internal module fault, wiring issue, or communication bus problem.
The module itself has an internal electronic or firmware fault causing it to transmit corrupted or out-of-range data.
Open circuits, shorts to power/ground, or corrosion in the harness between the module and the communication bus.
Loose, bent, or contaminated terminals at the module connector interrupting or corrupting data signals.
Bus wiring faults, termination issues, or interference corrupting messages from this specific module.
Mismatched software versions or incorrect vehicle configuration causing the gateway to reject valid module data.
Rare; the receiving module misinterprets valid data due to an internal processor or memory fault.
Yes, when this code is active the right side restraint system is typically disabled and may not deploy in a crash.
Low voltage can cause communication errors, but this code specifically indicates invalid data from the module, not just loss of communication.
No, the main control module is rarely the cause; the fault is almost always in the right side restraints module, its wiring, or connectors.
Clearing the code will not repair the fault; the restraint system will remain disabled until the underlying issue is fixed.
