U0454 code meaning
Invalid Data Received From Side Restraints Control Module - Right
What U0454 means
U0454 is the right-hand counterpart of U0453. Where a separate side restraints unit on the right evaluates side impact sensing or fires the right side and curtain airbags, a partner, normally the central airbag controller, stores U0454 when it judges that unit's messages corrupt or implausible. Contact itself still exists; a silent right unit would be U0153. No manufacturer documents U0454 publicly. Bosch describes airbag controllers with inputs for peripheral crash sensors that detect side impacts, and FMVSS 214 sets the side impact requirements such units serve. Because FMVSS 208 demands a readiness indicator for deployable protection, the airbag lamp is the expected reaction, and protection on the right may be missing until repair. No MIL is involved.
U0454 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0454
- Airbag warning lamp on
- Side or curtain airbag on the right possibly unavailable
Common causes of U0454
- Most likelyLoose or corroded plug of the right side unit, for example under the right seat or in the B-pillar
- PossibleSoftware or configuration of the right unit not matching the central airbag controller, often after a module swap
- Less likelyInternal fault of the right side restraints unit, for instance after a side impact on the right
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0454 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 54 | The exact fault in that area. |
What to do next
- Note U0454 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0454
What does U0454 mean?
U0454 means "Invalid Data Received From Side Restraints Control Module - Right". U0454 is the right-hand counterpart of U0453. It is a generic code, so it means the same on every make.
Is it safe to drive with U0454?
U0454 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0454 fail an emissions test?
U0454 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0454 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will U0454 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
