  3. C3 CHECK FOR CORRECT SJB OPERATION 
    • Disconnect all the SJB  connectors.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect all the SJB  connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    • Yes:  INSTALL a new SJB  . Refer to MULTIFUNCTION ELECTRONIC MODULE . TEST the system for normal operation.
    • No:  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
