U0474 code meaning
Invalid Data Received From Restraints System Sensor D
What U0474 means
U0474 flags unusable data from restraints sensor D. Chrysler's lists in NHTSA file PE11-019 assign D to the second left-side satellite acceleration sensor (internal fault B1B73, lost contact U0173). It appears only for the 2007-2008 Compass and Patriot, which carry six satellites, and is absent from the four-sensor Wrangler list. A later FCA layout with two side sensors per flank is the 2019 Cherokee: recall 19V-449 replaced two front sensors in the engine bay and four side sensors in B- and C-pillars, because faulty solder joints could cut them off from the occupant restraint controller and make airbags fire late or not at all. That recall names no letters, so the pillar behind D stays unconfirmed. Airbag lamp on; no MIL.

Symptoms of U0474
- Airbag warning lamp on
- Side impact sensing on the left reduced
Common causes of U0474
- PossibleCracked solder joint inside the satellite sensor
- PossibleConnector or wiring fault at the rear side sensor behind the pillar trim
- Less likelyRestraints controller configured for a different sensor layout
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0474 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 74 | The exact fault in that area. |
What to do next
- Note U0474 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.
