U0476 — Invalid Data Received From "Restraints System Sensor F"

vehicle network

Is it safe to drive?

Drive with caution The car drives normally, but with the SRS light on the airbags may not deploy in a crash. Treat it as a safety-critical repair: fine to drive to the shop, not fine to ignore for months.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm U0476 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many U0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the airbag / restraint system (SRS) for damage, corrosion, chafing or poor contact.
  4. Subsystem check Read the SRS module with a scanner that supports airbag systems — generic OBD2 readers cannot see these codes.
  5. Subsystem check Inspect under-seat connectors — they are often disturbed by seat movement or cleaning.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm U0476 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for U0476 (parts and labor, USD, independent shop rates): Reconnect or repair SRS wiring/connectors: $80–$250; SRS module reset or replacement: $300–$1,000; Replace a sensor or clockspring: $150–$500. Overall, fixing U0476 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

How much does it cost to fix U0476?

Reconnect or repair SRS wiring/connectors — $80–$250; SRS module reset or replacement — $300–$1,000; Replace a sensor or clockspring — $150–$500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What are the symptoms of U0476?

Drivers most often notice: no other driving symptoms, airbag system disabled message, airbag (SRS) warning light on.

What does OBD2 code U0476 mean?

Invalid Data Received From "Restraints System Sensor F" (U0476): a vehicle network fault affecting the airbag / restraint system (SRS). Short, gentle driving to a shop is usually possible. Most often caused by failed clockspring (driver airbag circuit), depleted backup battery or low system voltage, SRS control module fault or stored crash data.

How do I diagnose U0476 myself?

Start with a scan: confirm U0476, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the airbag / restraint system (SRS), and verify the suspect component against live data before buying parts.

What does U0476 mean?

Behind U0476 is a specific failure in the airbag / restraint system (SRS): invalid data received from "restraints system sensor F". The onboard computer stores it in the vehicle network group after verifying the fault over repeated checks.

To set U0476, the control module compares live readings of the airbag / restraint system (SRS) against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.

What causes U0476?

  • faulty impact or occupancy sensor
  • failed clockspring (driver airbag circuit)
  • SRS control module fault or stored crash data
  • depleted backup battery or low system voltage
  • damaged wiring under seats or in the steering column

Common symptoms of U0476

  • no other driving symptoms
  • airbag system disabled message
  • airbag (SRS) warning light on
