Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.

Was your vehicle in an accident? have you done any other repairs?
Start by checking the sensors. The Up-Front Right and Up-Front Left Satellite Acceleration Sensors are located behind the Front-End Module carrier and below the front lamp unit housing inboard end in the engine area. If the sensors are OK, then you may have a problem with the Occupant Restraint Controller (ORC). The U0019 code is for circuits that power many other systems, but since you have a problem with the air bag system, then you must check the Occupant Restraint Controller (ORC).
