This code indicates that a control module has received implausible or invalid data from a specific restraint system sensor, labeled as Sensor C. It points to a communication fault within the Supplemental Restraint System (SRS) network rather than an engine performance issue. The vehicle may not deploy airbags correctly if this fault remains active.
The specific impact or satellite sensor identified as Sensor C may be internally failed or sending erratic signals.
Harness damage, chafing, or loose connections in the SRS circuit can corrupt data transmission.
Moisture intrusion or oxidation at the sensor connector can cause high resistance or signal interference.
The airbag control unit itself may have internal processing faults preventing correct data interpretation.
Issues with the CAN bus or proprietary SRS network wiring can lead to data validity errors.
Extremely rare; the powertrain computer is rarely involved in SRS sensor data validation unless acting as a network gateway.
No, this code relates to the safety airbag system and does not control engine operation.
No, replacing the PCM is rarely the fix for SRS communication codes; focus on the sensor and wiring first.
The vehicle will drive normally, but the airbag system may not deploy in a collision, posing a safety risk.
Usually no, SRS codes often require a specialized scan tool to clear after repairs.
