  1. K1 RETRIEVE THE DTCs 
    WARNING: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.
    NOTE: If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the SRS must be depowered.  Refer to SUPPLEMENTAL RESTRAINT SYSTEM .
    NOTE: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a SRS fault.
    NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
    NOTE: The memory seat track position sensors are integral to the memory seat track motors. The memory seat track motor electrical connectors will connect to a seat track without the memory option. When installing a new seat track, make sure the correct memory or non-memory seat track is being installed.
