U047E — Invalid Data Received From "Restraints System Sensor N"

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

Read the code and freeze frame Connect an OBD2 scanner, confirm U047E is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
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.
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.
Subsystem check Read the SRS module with a scanner that supports airbag systems — generic OBD2 readers cannot see these codes.
Subsystem check Inspect under-seat connectors — they are often disturbed by seat movement or cleaning.
Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm U047E does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for U047E (parts and labor, USD, independent shop rates): Replace a sensor or clockspring: $150–$500; SRS module reset or replacement: $300–$1,000; Reconnect or repair SRS wiring/connectors: $80–$250. Overall, fixing U047E 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

What does OBD2 code U047E mean?

Invalid Data Received From "Restraints System Sensor N" (U047E): a vehicle network fault affecting the airbag / restraint system (SRS). Short, gentle driving to a shop is usually possible. Most often caused by depleted backup battery or low system voltage, damaged wiring under seats or in the steering column, failed clockspring (driver airbag circuit).

Is it safe to drive with U047E?

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.

Will U047E clear itself?

Sometimes U047E clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

How do I diagnose U047E myself?

Start with a scan: confirm U047E, 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 are the symptoms of U047E?

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

What does U047E mean?

Behind U047E is a specific failure in the airbag / restraint system (SRS): invalid data received from "restraints system sensor N". The onboard computer stores it in the vehicle network group after verifying the fault over repeated checks.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with U047E — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

What causes U047E?

failed clockspring (driver airbag circuit)
SRS control module fault or stored crash data
damaged wiring under seats or in the steering column
faulty impact or occupancy sensor

Common symptoms of U047E

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

How to fix U047E

Start with the cheapest and most common causes before replacing expensive parts:

Replace a sensor or clockspring — $150–$500
SRS module reset or replacement — $300–$1,000
Reconnect or repair SRS wiring/connectors — $80–$250
