What Does The Chrysler U1213 Code Mean?

Impact sensors perform their own self test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the module. The repair of this fault centers on verifying the integrity of the sensor’s internal circuitry and software validity. Refer to the enclosed graphic as a reference of specific Side Impact Satellite Acceleration, Side Impact Satellite Pressure, and Up-Front Satellite Acceleration sensor locations on the vehicle. It is important to review this graphic thoroughly to understand the specific area of diagnosis you are looking to complete.
