STARTING SYSTEM


  1. SYSTEM CONTROL


    1. Once the engine switch is pushed, this function continues to operate the starter until the engine starts, provided that the brake pedal is pressed and the shift lever is in P*1 or N*1, or the clutch pedal*2 is depressed. This prevents starting failures and the engine from being cranked after the engine has started.

    2. This system cuts off the current that powers the accessories while the engine is cranking to prevent the accessory illumination from operating intermittently due to the unstable voltage that is associated with the cranking of the engine.

    3. When the certification ECU (smart key ECU assembly) detects a start signal from the engine switch, this system monitors the engine speed (NE) signal and continues to operate the starter until it determines that the engine has started. Furthermore, even if the certification ECU (smart key ECU assembly) detects a start signal from the engine switch, this system will not operate the starter if the certification ECU (smart key ECU assembly) has determined that the engine has already started.

    4. After the starter operates and the engine speed becomes higher than approximately 400 rpm, the certification ECU (smart key ECU assembly) determines that the engine has started and stops the output of the STAR signal to the starter relay assembly. Thus, the starter operation stops and the certification ECU (smart key ECU assembly) energizes the ACC relay.

    5. If the engine has any failure and does not start, the starter operates as long as its maximum continuous operation time and stops automatically. The maximum continuous operation time is approximately 5 seconds through 30 seconds depending on the engine water temperature condition. When the engine water temperature is extremely low, it is approximately 30 seconds and when the engine is warmed up sufficiently, it is approximately 5 seconds.
