  2. Tail lamp auto cut
    1. IGN KEY is OUT when turning Tail lamp switch ON following IGN KEY ON and Tail lamp is automatically OFF (auto power off) when turning ON Driver door open switch.
    2. Tail lamp is automatically OFF (auto power off) when turning ON Driver door open switch with IGN KEY ON, and then IGN KEY OUT.
    3. If turning Tail lamp switch ON and OFF in turns following auto power off, Tail lamp is ON and AUTO CUT function is disabled.
    4. If IGN KEY is ON again after auto power off, Tail lamp is ON and AUTO CUT function is disabled.
    5. AUTO CUT mode is maintained when changing BATTERY.

  3. Head lamp low control
    1. If turning Head lamp low switch ON with IGN1 ON, Head lamp low is ON.
    2. If IGN1 is OFF or Head lamp low switch is OFF, Head lamp low is OFF.
    3. If IPM does not work with IGN1 ON, Head lamp low Output should be automatically ON.

  4. Head lamp low signal control
    1. If Head lamp low output is ON by 'Head lamp low switch ON' or 'Auto light function', Head lamp low control output is ON.
    2. If Head lamp low output is ON by 'DRL EUROPE function', Head lamp low control output is Off.
    3. If Head lamp low output is turned ON → Off, Head lamp low control output is Off.
  5. Head lamp high control

    Head lamp high Input and Head lamp Passing Input by M/F are controlled by single input of Head lamp high switch.

    1. Head lamp high Input

      Determined by Head lamp high Input when Head lamp high switch ON with Head lamp low control output ON by IPM, and IGN2 ON.

    2. Head lamp Passing Input

      Determined by Head lamp passing Input when Head lamp high switch ON with Head lamp Low control Output OFF and IGN2 ON.

    1. If Head lamp high Input is ON with IGN2 ON, Head lamp high output is ON.
    2. If Head lamp passing is ON with IGN2 ON, Head lamp high output is ON.
  6. Auto light control
    1. Auto light function is not applicable for Europe DRL option (DRL option=GND).
    2. If Auto light power is less than 4V or more than 6V with IGN1 ON & IGN2 ON, it is considered to be malfunctioning. In this case, Head lamp LOW is ON with Auto light switch ON no matter what the value of Auto light sensor is. Filtering time of failing and recovering supply power takes 300msec each.
    3. If Auto light sensor value is adaptable with the condition of Auto light Control, turn light ON immediately.
    4. If Auto light sensor value is equal to the Input value of light ON with IGN1 ON & IGN2 ON, Auto light switch ON, and light OFF, turn light ON after T1: 2.5 ± 0.2sec.
    5. If Auto light sensor value is equal to the Input value of light OFF with light ON, turn light OFF after T2: 2.5 ± 0.2sec.
    6. When turning OFF Auto light switch, immediately turn OFF light.
    7. Auto light sensor value for light ON is as following.
      AUTO LIGHT SENSOR VALUE CHART

        TAIL LAMP HEAD LAMP LOW
      ON 2.7±0.05V
      OFF 4.3±0.05V
    8. TIME CHART based on Filtering time and sensor value in each application region is as following.

      T1 : 2.5±0.2s, T2: 2.5±0.2s

  7. Tail interlocking AV control
    1. Tail Interlocking AV control function is not applied to Europe DRL option.
    2. If Auto light power is less than 4V or over 6V with ACC ON, it is considered to be malfunctioning. AV Tail Output should be OFF in malfunctioning.
    3. Power supply Filtering time of failing and recovering takes 300msec each.
    4. If Auto light sensor value is equal to the input value of Tail lamp ON with ACC ON, turn ON AV Tail Output after 2.5 ± 0.2 sec.
    5. If Auto light sensor value is equal to the input value of Tail lamp OFF with AV Tail Output ON, turn OFF AV Tail output after 2.5 ± 0.2sec.
    6. Auto light sensor value of light ON is as follows.

  8. Day time running light

    DRL (DAYTIME RUNNING LIGHT) option is categorized into 2 types, based on DRL option Input.

    1. NON-DRL OPTION: DRL option is not connected. (Switch Open)
    2. DRL OPTION: DRL option is connected for having ground. (Switch Short To GND)

    DRL option is input on a regular basis, and to be based on availability of immediate function.

    1. If IGN2 & Alt L ON, DRL is functioning by controlling Head lamp high output with PWM.
    2. Head lamp high output is restricted to frequency: 80Hz/Duty 50% during operating DRL.
    3. If Head lamp low is ON with head lamp low switch ON or by functioning Auto light, the function of DRL is cancelled.
    4. If Head lamp high is ON by turning ON Head lamp high switch, the DRL function is cancelled.
    5. If Parking brake switch is ON (PARK), the DRL function is cancelled.
  9. Escort function
    Fig 8: Escort Function Chart

    1. Door Lock 2 times : Tx Door Lock 2 times
    2. When Open the Driver door, former 2 times lock counter is cleared, and Start new 2 times lock counting during the Escort function (counting 30sec).

      If Driver door is re-opened, re-start 20min counter and if Driver door is re-close, re-start 30sec counter.

  10. Front fog lamp
    1. If turning OFF front fog lamp switch with front fog lamp ON, turn OFF front fog lamp. (Front fog lamp switch is Lock type Switch)
    2. When turning IGN2 OFF with Front fog lamp ON, turn OFF Front fog lamp.
    3. When turning ON Head lamp high switch with Front fog lamp ON, turn off Front fog lamp. If turning Head lamp high switch off another time, turn on Front fog lamp.
