U0250Lost Communication With Impact Classification System Module

U0250 means the vehicle's main computer has lost communication with the impact classification system module, which is the component that tells the airbag control unit how severe a crash is so it can deploy the right restraints. The computer detects this when it stops receiving the module's periodic status messages over the controller area network (CAN) bus for a set period.
