U0476 code meaning
Invalid Data Received From Restraints System Sensor F
What U0476 means
U0476 is stored when restraints sensor F still reports but its values fail the receiver's checks. Chrysler's lists in NHTSA investigation PE11-019 make F the first right-side satellite acceleration sensor, fitted even to the four-sensor Wrangler JK; internal fault B1B75, lost contact U0175. The side has little crush space, so this sensor must deliver usable data within milliseconds. FMVSS 214 sets the side impact tests such sensors help pass, a moving deformable barrier and a pole impact. When the right sensor sends garbage, deployment of the right seat and curtain airbags is no longer assured. Airbag lamp on, no MIL.
U0476 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.8 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0476
- Airbag warning lamp on
- Right side and curtain airbag readiness uncertain
Common causes of U0476
- Most likelyWiring or connector fault at the right side sensor under the pillar or sill trim
- PossibleRight side sensor damaged or misaligned after a side impact or body repair
- Less likelyInternal fault in the satellite sensor
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0476 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 76 | The exact fault in that area. |
What to do next
- Note U0476 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 U0476
What does U0476 mean?
U0476 means "Invalid Data Received From Restraints System Sensor F". U0476 is stored when restraints sensor F still reports but its values fail the receiver's checks. It is a generic code, so it means the same on every make.
Is it safe to drive with U0476?
U0476 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0476 fail an emissions test?
U0476 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 U0476 to fix?
Difficulty: hard. A typical repair takes 0.8 to 2.5 hours of work. This is a job for a workshop.
Will U0476 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
