What Does U0476 Mean?
The airbag control module is receiving corrupted or implausible data from restraint system sensor F (typically another rear or side sensor in multi-sensor systems). The data quality or validity from this sensor is compromised.
Safety Warning
Critical safety concern. Compromised restraint system sensor reduces effectiveness of airbag deployment algorithm. Professional repair required before driving.
Common Causes
35%
Faulty or damaged restraint system sensor F (accelerometer/impact sensor)
30%
Corroded, loose, or damaged wiring harness connections to sensor F
20%
Water intrusion or corrosion in sensor F connector
10%
Failed airbag control module misinterpreting sensor data
5%
CAN bus communication fault or network interference
Diagnostic Steps
1
Step 1: Monitor sensor F data stream with scan tool to identify abnormal readings, intermittent data loss, or incorrect values
2
Step 2: Locate sensor F (position varies by vehicle design, often rear quarter panel or opposite side rear) and check for damage or moisture
3
Step 3: Disconnect sensor F connector and inspect for corrosion, bent terminals, or poor contact; clean and apply dielectric grease
4
Step 4: Test sensor F electrical circuits including power, ground, and signal wires for shorts, opens, or high resistance
5
Step 5: Replace sensor F if confirmed defective; perform airbag system self-test and verify all codes clear successfully
Estimated Repair Cost
$200 - $800
Parts + labor, varies by vehicle and location
The airbag control module is receiving corrupted or implausible data from restraint system sensor F (typically another rear or side sensor in multi-sensor systems). The data quality or validity from this sensor is compromised.
The most common cause of U0476 (Invalid Data Received From "Restraints System Sensor F") is: Faulty or damaged restraint system sensor F (accelerometer/impact sensor)
Typical repair costs for U0476 range from $200 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Critical safety concern. Compromised restraint system sensor reduces effectiveness of airbag deployment algorithm. Professional repair required before driving.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0476 to identify the root cause.
