When the ignition switch is placed in the START position, fused ignition voltage is sent to the start diode in the battery junction box (BJB) along circuit CDC35 (BU/WH) and then to the smart junction box (SJB) and the PCM along circuit CE619 (BU/BN). The ignition switch is spring loaded to automatically return to the RUN position after being placed in the START position.
